Secrets of the Houston Warehouse
by Dave Scott
(Editor’s introduction: Many, many years ago, when the earth was young, and the oceans still
covered much of the land, and dinosaurs were to be found on every street corner... okay, if you insist
on a date, it was 1993... we published the first of five Special Issues... and in a burst of creativity, we
elected to call this one “Special Issue No. 1”. Unfortunately, the first two Special Issues are long since
sold out, and those few that infrequently come on the market often carry price tags that look like the
Gross National Product figure of some third world countries. That first issue carried an article by Dave
Scott that we still receive a dozen or more calls a month asking for copies of. After a half dozen calls
this week, we have decided to save ourselves a lot of wear and tear on our photocopier, and reprint the
article... one of the most popular, and most quoted pieces that we ever carried.)
In 1975, when a Houston concrete contractor opened the doors of his new business venture, the
event didn’t exactly make ripples among the benchrest community. The project, an enormous
warehouse on Houston’s east side, was built solely to be leased for industrial storage. And if the event
went unnoted, its builder, Virgil King, was equally unknown to group shooters. No one could have
predicted that the Houston Warehouse and Virgil King would write one of the more fascinating
chapters on the subject of extreme rifle accuracy.
From the beginning, the warehouse was utilized as planned. First, tons of telephone directories
were stacked on its floor; then an oil company leased the structure to store plastics.
All the while, Virgil and a neighbor, veteran shooter Bob Fisher, were kicking around an
interesting idea. Even though the building was in full use, it had an unobstructed fire lane that was 30
feet wide and ran the full length of the mammoth structure — 325 yards. Moreover, although
employees of the leasing oil company were in and out during the work day, the building was deserted
nights and weekends. Virgil saw an opportunity to test his most accurate gun, a Shilen-barreled .25/06
hunting rifle, in ideal shooting conditions.
Bob Fisher, a benchrest shooter, had other things in mind. He was awed when first he stood in
the enormous warehouse. The floor was thick concrete, poured to withstand hundreds of tons of
storage. The walls were 6" concrete without windows. The roof soared 45 feet above floor level. In
short, it was obvious to Bob that this building had the potential of becoming the best shooting
environment an accuracy fanatic ever popped a primer in. It literally was a benchrest shooter’s dream
come true, the Camelot of shooting ranges. Here, the breezes never blew, the mirage never shimmered,
the sun never set and the rain never fell. Even the harshness of the weather, either heat or cold, was
moderated by the insulating properties of the walls and steel roof.
The two shooters began by constructing a combination bullet trap and target holder utilizing
sand contained between walls of 1 1/2" steel plate and a face of 3/4" plywood. Although the heavy
device was mounted on casters, Virgil decided it would remain stationed against a wall at one end of
the warehouse. To change shooting distances, the bench would be moved along the fire lane.
The warehouse already had fluore-scent lighting throughout, but special illumination would be
needed at the target. Bob Fisher, an electrical contractor, wired a mix of mercury vapor and quartz
lighting. In combination with the fluorescent lamps, it faithfully reproduced normal outside lighting at
the target. With the exception of a portable floor lamp used to eliminate shadows, the lights were
mounted on the ceiling to prevent their heat from interfering with sighting.
The two shooters built a sturdy, wooden bench but quickly abandoned it when they discovered
that placing a hand on its top displaced the crosshairs at the target. They also committed a major error
in constructing the bench and stool as a single unit. Every bodily movement was transmitted to the
rifle. The shooters correctly decided there was no point in having a million-dollar shooting range with
a two-bit bench.
Determined to convincingly rectify his initial mistake, Virgil poured a massive 700-pound
concrete bench consisting of a 6"-thick, steel-reinforced top perched on three legs of 6" steel pipe. To
be on the sturdy side, he ran iron rods inside the legs and filled them with concrete. The stool was also
three-legged and independent of the bench.
Since this ponderous shooting platform was a tad hefty to be manually hauled about, a heavy
industrial caster was mounted on an eccentric at the foot of each leg. Rotated down, the casters allowed
the bench to freely roll. With the casters raised, the bench sat solidly on its legs.
With the range now perfected, a minor and somewhat nagging difficulty had to be overcome.
In the sealed environment of the warehouse, there was no breeze to dispel the mirage rising from a
heated barrel. Because a scope tube’s bulk may damage a fragile scope, or the tube itself may heat up
and introduce mirage, fanning the barrel with a piece of paper became for standard procedure for a
while.
Finally, in a bold stroke of technological innovation, Bob brought in a small electric fan.
Carefully directed over the barrel, the puny appliance effectively cleared away the barrel mirage. Care
was exercised, however, not to allow errant air movement to invade the sensitive muzzle area and
thereby deflect the bullet from its true path.
And so began perhaps the most insightful, revealing experimentation into practical rifle
accuracy ever conducted. Over a period of six years, the levels of accuracy achieved in the Houston
Warehouse went beyond what many precision shooters thought possible for lightweight rifles shot from
sandbags and aimed shot-to-shot by human eye. For the first time, a handful of gifted, serious
experimenters — armed with the very best performing rifles (with notable exceptions) — could boldly
venture into the final frontiers of rifle accuracy, a journey made possible by eliminating the baffling
uncertainties of conditions arising from wind and mirage.
Under these steel skies, a shooter could, without question, confirm the absolute limits of
accuracy of his rifle, or isolate the source of a problem. In the flawlessly stable containment of the
Houston Warehouse, only four general categories of accuracy problems were possible: the rifle, the
scope, the load or the shooter. For the first time, a very few exceptional rifles would display the real
stuff, drilling repeated groups measuring well below the unbelievably tiny .100" barrier. The bulk of
rifles, however, embarrassed their owners.
For the most part, shooters arrived at the warehouse with troubles. Their rifles were
inconsistent — one group in the teens, the next in the .3’s — for reasons they could not fathom.
Others had consistent .25" to .30- something rifles, an accuracy level guaranteed to put a competition
shooter down near the bottom of the pack. With the list of potential problems significantly narrowed
by the elimination of moving air and dancing heat waves, the answers were easier to isolate in the
warehouse, and shooters drove hundreds of miles or flew into Houston to get to the source of their
tribulations.
Some of the best benchrest marksmen in the nation showed up with rifles they hoped would
somehow perform much better in Virgil’s concrete sanctuary than out there where the flags flutter.
Still others wanted merely to shrink the bullet dispersion of a superb rifle a few additional thousandths
of an inch by careful tuning, a task that could not be accomplished at an outside range cursed with the
vagaries of natural conditions. Some departed enlightened. Others stalked away disgruntled.
The discoveries made there, some reported in Precision Shooting by T.J. Jackson, were
sometimes controversial, but always fascinating. Circulating around at that time were mutterings that
the warehouse conditions were flawed and the shooting there invalid. From what I knew about the
warehouse, I wondered how anyone could fault it. After all, some of the shooters were firing
numerous consecutive groups measuring “in the zeros”. Flawed conditions, indeed!
For those of us who are strangers to groups “in the zeros”, we’re talking about 5 shots at 100
yards that are, at first glance, indistinguishable from a single shot. The bullets sizzling through the
same hole merely worry away the tortured edge of the target paper in varying degrees until the hole is
enlarged less than .100" over bullet diameter. Often much less.
For years, many of us expectantly thumbed through the pages of Precision Shooting, searching
for more information from the Houston Warehouse. Col. Jackson, a highly respected benchrest shooter
and gunsmith who frequented the warehouse, occasionally dropped us a crumb — and sometimes a
bomb. But it was never enough. In late 1985, two years after the warehouse mysteriously passed into
obscurity, a frustrated Dave Brennan confessed that one of the great disappointments of his editorship
was that he had never received a comprehensive write-up on the shooting that went on there.
In 1983, as suddenly as it all began, the Houston Warehouse shut its doors to the men who
mysteriously arrived in the night. The gunshots faded away. And with them died the hopes of many
of us. Now we might never know what happened behind those sturdy concrete walls. Gone was the
possibility, however remote, that any one of us would ever sit at the massive bench and launch a bullet
into perfectly still air. With sinking hearts, we realized it was the end of an era that might never come
again.
In June of this year, I contacted T.J. Jackson in Austin and asked if he would consent to an
interview on the Houston Warehouse. T.J. graciously offered to help, but suggested I contact Virgil
King, since only Virgil was present every time shooting occurred in the warehouse. T.J. had reported
in PS that Virgil was the primary shooter. Col. Jackson described him as having a superior delivery —
“delivery” meaning bag technique, or the mechanical ability to return, position and fire the rifle
identically each time. Unfortunately, T.J. had no idea how to contact Virgil.
Three nights after I talked to T.J., the phone rang at 9:45. The caller introduced himself as the
caretaker of the Houston Warehouse. Virgil had read my recent Precision Shooting article on neck
clearance and wanted to discuss some of his thoughts on that subject. Somewhat stunned at this
fortunate coincidence, I listened intently for over an hour as Virgil spoke of case necks, shooters and
the Houston Warehouse experience. Finally I asked if he would be agreeable to an interview. He was
reluctant, but at least I managed to obtain his phone number.
A couple of weeks later, after several abbreviated conversations with his answering machine, I
reached him again. This time, Virgil kindly consented to sparing me a couple of hours to tape a
conversation on shooting and the warehouse. In order that neither of us spend all morning driving,
Virgil suggested we meet about halfway between our homes — at Shilen Rifles in Ennis, Texas.
On the appointed day, Ed Shilen, a mutual friend of Virgil’s and mine, introduced us, then
departed for an afternoon of sailplane soaring. In the quiet of Ed’s office, Virgil began to vividly
sketch what many of us had tried to envision. He spoke with great clarity and sharp memory of events
that concluded a decade ago.
“The shooting would generally start about 10 at night,” he began. “Everything settled down,
and the air got real still. It just felt right. Then it was like shooting outside, except there was no wind
or mirage. If you had a rifle that would shoot, it would shoot. If you didn’t, you found out pretty
soon that you had a problem.”
“Downrange at 100 yards,” he continued, “if a rifle was really cooking, through the spotting
scope you’d see the hole in the target open up black when the bullet passed through, then the paper
would spring back and close a little bit. And if the group was .035" or so, you couldn’t see the
difference between it and one bullet hole through a 36X spotting scope.”
A unique feature of the Houston Warehouse was the fact that it indeed had similarities to
shooting outside. Unlike shooting tunnels, where the shooter must wait between shots for powder gases
and heat to clear, firing in the vast expanses of the warehouse could be conducted at any pace. The
offending products of combustion rapidly floated to the roof, high above.
As already indicated, of the handful of riflemen who ever fired in the warehouse, a high
percentage had problems. On occasion, experimentation would continue all night or all weekend, as a
shooter refused to accept the fact that his rifle simply was not going to perform. When this occurred,
Virgil and his shooting guest spread cardboard on the hard warehouse floor and rested periodically,
then went back to it again.
“It was pretty frustrating,” Virgil admitted, “because in the warehouse I could fire three groups
in any rifle and tell you if that rifle was going to shoot really well.”
“Still,” Virgil explained, “I felt that I owed any shooter who either drove hundreds of miles or
flew into Houston the opportunity to prove to himself that his rifle just was not going to shoot. If that
took hours or days, that’s the way it was going to be.”
Numbered among those who showed up with rifles not measuring up to expectations were
distinguished personages such as Don Geraci, Harold Broughton, Ed Shilen, Frank Wilson, Henry
Christman, John Jones, Wilbur Cooper, Col. Jackson, Jim Goddard, Jim Williams, and Bob Fisher.
Most of the disappointed shooters reworked their equipment and returned. Those who returned
generally trotted out vastly improved guns.
That’s not to say that the bulk of rifles showing up there — even the reworked ones — would
shoot in the zeros. Virgil estimated he could count on his fingers the rifles he had seen that would
consistently shoot to this awesome accuracy level. T.J. Jackson owned two such rifles, both chambered
by him for 6BR. One of his rifles, a Heavy Varmint class gun, consistently shot .050". The other, a
lighter rifle, would hold at about .060". T.J. also built an exceptional 6PPC for a customer, which T.J.
later purchased. Why? We can assume part of the reason is that it grouped at the .050" level. Frank
Wilson had two rifles that would shoot in the zeros, but only after they had been reworked.
“We figured any gun was really shooting,” Virgil explained, “when it would shoot five
consecutive groups that were identical in shape and less than .080”.
The most accurate rifle ever to punctuate the stillness of the Houston Warehouse happened to
be Virgil King’s own 10 1/2-pound Light Varmint benchrest rifle. The rifle was built around an action
made to Virgil’s specifications by Houston shooter Wilbur Cooper, a mechanical engineer, master
machinist and fanatical perfectionist. The action was machined from #416 stainless steel and had an
integral sleeve extending 5/8" forward around the barrel, but not touching it, to provide additional
bedding surface. Virgil said the tolerances were held so close in this action that he estimated, as an
example, that the clearance between the bolt and boltway measured perhaps a minuscule .0001" on all
sides. Consequently, simply inserting the bolt took a measure of concentration.
T.J. Jackson chambered its Shilen Select Match Grade 8-groove barrel for a .050"-shortened
version of the 22PPC. He also turned the outside of the barrel to ounce-saving dimensions which
permitted an oversized #7 contour to be used without the rifle exceeding the weight limit for Light
Varmint class. The barrel was cut to 21 3/4" and target crowned.
Lapping compound was then smeared on the barrel threads, and by applying outward pull, the
barrel was lapped into the action threads for full, positive contact. Virgil pointed out that if this
procedure is not accomplished, only one thread or parts of one or several threads may be making
contact. Anything less than full thread contact, he underscored, is destructive to finest accuracy.
During the lapping operation, great care was exercised to align the barrel straight with the
receiver. Virgil used no mechanical means. He simply used his hands and a delicate degree of “feel”.
He stressed that this step should be done with great moderation. A little lapping here goes a long way.
Part of the reason for lapping-in the barrel and receiver threads is to help center the barrel in
the precise middle of the receiver. The superb precision gunsmiths who build benchrest rifles correctly
cut the barrel threads slightly loose. While this serves several essential purposes, there is no guarantee
that the barrel will “center” when it’s run up and tightened. Lapping helps eliminate this uncertainty.
Virgil confessed that lapping would not have been necessary on his rifle if he, Wilbur Cooper
and seasoned shooter John Jones had not been tardy in developing an important innovation in the
mating of the barrel to the receiver. Too late to benefit Virgil, the three jointly conceived the idea of
undercutting a 45-degree slope on the inside edge of the receiver ring, leaving about two-thirds of the
receiver shoulder untouched and square. Another 45-degree slope, cut farther inside the receiver (on a
Cooper action), terminated at the locking lugs. With the barrel precisely cut to snug up against the two
sloped areas, as well as the receiver shoulder, perfect barrel centering became absolute and positive.
With the lapping done, Virgil next disassembled his Burns conversion Remington trigger and
polished it to a mirror-smooth finish, setting it at a delicate 1/4 ounce. He also specified that the firing
pin spring inside the bolt be as strong as feasible.
The barreled action was zero-tolerance bedded and then glued in a McMillan stock. Two
action screws were also installed in place. In tuning this finely accurate rifle, Virgil firmed up the
middle screw to correct a tendency for slight vertical dispersion.
He mounted a Lyman-Siebert 30X scope in Bausch & Lomb rings that had been painstakingly
lapped so only a tiny amount of crosshair correction was needed to bring the gun on target. The rings
were set on Weaver bases.
The finished rifle made its weight limitation by the skin of its teeth, which did nothing for the
appearance of this exceptional gun. Spraying the stock would have catapulted it into the Heavy
Varmint ranks. Therefore, the stock permanently retained its unfinished fiberglass appearance.
If the rifle looked like the devil, it shot like the hammers of hell. “Day after day, week after
week”, Virgil recalled “it would NOT shoot a group in the warehouse bigger than .070". You had to
cheek it or thumb it to get it to shoot that big. Generally, it shot .035" to .050", with most groups
holding around .035". But now and then you’d sneak one in a little better than that.”
Friends, we’re talking about firing group after group approximately the same size as the gap
on your spark plugs. This, with the barrel cleaned between every six shots — one group plus one
fouler. But didn’t he get an occasional larger group? Something really horrible, something maybe in
the (shudder) teens? “Not unless you did something wrong,” Virgil responded indignantly, flinching
at the implication of his rifle sinking to that dismal level.
How could the rifle and the man behind it be that consistently accurate? Virgil told me in
great detail. “First, you shoot free-recoil. After a while, after all the thousands of rounds I fired in the
warehouse, I developed a technique that was practically infallible. I did exactly the same thing every
shot. I was like a machine, and once you find out what works, you don’t change anything. We
discovered that if you want a gun to really shoot, you can’t cheek it, you can’t shoulder it, you can’t
hand it, you can’t thumb it. The only thing you touch is the trigger, and I tried to put my fingerprint
on the trigger exactly where my last fingerprint was. I didn’t even touch the bench. I planted my feet
solidly on the floor and kept them right there.
“Your shoulder should be 3/16" to 5/16" from the stock so you can catch the rifle immediately
when it recoils back,” Virgil advised. “Otherwise the rifle will get back too far and disturb the rear
bag.”
The rear bag and the way you manage it is crucial, Virgil explained. First, he positioned the
rifle on the bench so the stock barely protruded from the “V” of a rabbit-ear bag, then he pounded the
stock firmly into the bag. As already mentioned, when the rifle recoils, it’s important that the bag stay
put. With proper bag technique, when the rifle is returned to its firing position, any sight corrections
should be slight and made by tiny manipulation of the rear bag. The less bag adjustment, the better.
Consistency is everything.
Virgil packed his rear bag very firm with casting sand, which is about 33% heavier than
common sand. He then applied water and formed the “V” to the rifle stock by pounding the stock into
the bag and allowing the leather to dry. Done only once, this step hardens the leather and makes the
stock slide smoother. A mixture of equal amounts of talcum powder and white graphite applied to the
back and front bags provided smooth sliding of the rifle, even in very humid conditions.
He packed the front bag as hard as iron. Here he employed a one-to-three mixture of Portland
cement and casting sand. The cement doesn’t set, but it does help hold the bag shape by resisting the
twisting force imparted to the fore-end by bullet torque.
Virgil fired his many zero-level groups without any side support for the front bag, but he
strongly advocates the pedestal fore-end stop. He adjusted the stop so the front bag supported the
fore-end about halfway from the end of the fore-end to the receiver. He said if the bag is positioned
farther forward, this part of the stock is too springy, and accuracy will suffer.
When Virgil returned his rifle after firing, he bumped the fore-end stop and then pulled the
rifle back “one-millionth of an inch”. In the warehouse, he found that contact between the stop and
stock tended to deteriorate accuracy.
The Houston Warehouse was the perfect setting for building a load. In years of watching his
rifles and a few others punch microscopically enlarged holes in targets, he recorded some interesting
observations. “In the summer,” Virgil noted, “the sharpest groups we could get out of the 6PPC was
with Winchester
748 powder. But when the temperature fell below, say 70 degrees, it wouldn’t shoot. We’d have to go
to H322.” His Gilmore-chambered Shilen 8-groove 6PPC barrel on the Cooper action produced groups
a bit looser than the 22PPC barrel, averaging about .070".
In this shortened 22PPC, he used IMR4198 exclusively. He adopted this powder after Don
Geraci, an advocate of 4198, visited the warehouse. Although 4198 has a reputation for varying
considerably from lot to lot, Virgil never bothered to lay in a big supply of any particular batch. “I
just went out and bought some when I needed it,” he said. “Lot number didn’t make any difference.”
Within limits, neither did powder charge. Virgil threw his charges from a Culver conversion,
and the grain-cutting operation obviously gave him reasonably consistent results with the long, little
kernels, considering the excellence of the resulting groups. He did, however, later use a Belding &
Mull powder measure in order to lessen the grain-cutting problem.
Powder charges, as long as they were fairly consistent and bracketed within a couple of grains,
were not important, he said. On one occasion, as an experiment Virgil shot one group with his 6PPC
barrel on the Cooper action using a 53 Culver setting of Winchester 748, the next 52 and the third 51.
All three groups were identical.
He shot the now-discontinued 68-grain Remington Bench Rest Bullets in his 6PPC barrel and
52-grain Remington Bench Rests in the 22PPC. “I decided on the Remington bullet in the beginning,”
Virgil explained. “I developed my brass to work with it, and I really didn’t experiment with any
others.”
Virgil added that although he never saw an inaccurate primer, he went with the prevailing
opinion and used Federal 205M’s. They were seated with a Lee tool, and he was unable to detect any
accuracy variances resulting from seating pressure. Apparently, as long as the primer isn’t crushed and
ruined in seating, nothing else in seating really matters.
One thing that IS important is that the bullet be precisely seated against the lands. T.J. Jackson
reported this fact in the May 1987 issue of Precision Shooting. In a letter to the Editor, T.J. wrote,
“...in all our testing in that Houston warehouse... and the dozens and dozens of groups that Virgil King
shot in there ‘in the zeroes’... he NEVER fired a single official screamer group when he was ‘jumping’
bullets. All his best groups were always seated into the lands, or at the very least... touching the lands.”
Virgil said his practice was to seat the bullets so the engraving was half as long as the width of
the lands. He noticed an interesting phenomenon with rifles that could really shoot: if the bullets were
seated a little short and the powder charge was a bit on the light side, the groups formed vertically. As
he seated the bullets farther out and increased the powder charge, the groups finally became horizontal.
If he went still farther, the groups formed big globs. He said the trick is to find the midway point
between vertical and horizontal. That point should be a small hole.
What were the velocities of his loads? Virgil doesn’t know or really care. “I didn’t work with
chronographs,” he said, “because as long as a bullet went into the same hole as the previous one, it
didn’t make any difference how fast it was traveling.” He confided, however, that his load of 4198 in
the 22PPC was a shade on the warm side.
Building a load is important, Virgil conceded, but “tuning” cases is what stands between you
and that final fraction of an inch that separates a good gun from a barn burner. “Tuning” cases goes far
beyond sorting, neck turning and prepping the primer pockets and flash holes. These case refinements
will get you only so far, Virgil stressed. To produce cases capable of shooting groups better than the
guy at the next bench, you have to go the extra mile. And you make the journey with sensitive hands
and a piece of #400 sandpaper.
For Virgil, the process started by purchasing a substantial number of Sako .220 Russian cases.
(Yes, Virginia, there once was such a case.) After the cases were weight sorted, he annealed the necks
with a small propane torch. He then loaded Bullseye powder behind toilet paper bullets and fired the
rounds in a special rifle assembled for this purpose. The necks of the fire-formed cases were next
inside bored. This was accomplished on a precision lathe, with the necks supported in a die during the
operation.
Virgil would then outside turn the necks for a total clearance of about .0007" between loaded
round and chamber. Since the neck turner left cutting rings, Virgil sanded the necks shiny smooth,
which typically resulted in a somewhat widened neck-to-chamber clearance of .00075". He emphasized
that until the hills and valleys were smoothed, the case neck was prevented from laying flat against the
chamber. Flash holes were cut identically and chamfered inside, but he didn’t uniform primer pockets
or turn the case bases. He also had not the foggiest idea what amount of case-wall variances existed in
any of his brass, but in those excellent Sako cases, probably not much.
Then came the final, critical step — the step requiring a sensitive touch and #400 sandpaper
— the “tuning” step. “The secret,” Virgil said, “is to get the neck tension — the grip of the brass on
the bullet — exactly the same on every case. You do this by firing the case and then feeling the bullet
slide in the case neck as you seat it. Here, a micrometer won’t do you any good. Feel is the whole
thing. If any case grips the bullet harder than the others, you take three turns over the sandpaper and
fire it again, until you get exactly the same amount of seating pressure. Until the necks were tuned, I
didn’t feel I was ready to start tuning the gun.”
Virgil continued: “You can change the powder charge slightly, and it won’t really make any
difference, but if you change the bullet seating depth or the grip on the bullet, you’re going to see bad
things happen fast.”
After a case has been fired a couple of times, another condition is created in the neck that
requires sensitive feel. A tiny groove pressed into the neck by the pressure ring on a flat-base bullet
causes the bullet to “snap” into place when it’s seated. Virgil emphasized that feeling the bullet slide
down the neck and then snap into place told him everything he needed to know about whether that
round was going to go into the group or not.
To sense these critical events, Virgil seated bullets in a Wilson straight-line tool BY HAND —
not arbor press. He estimated that the seating pressure on his hand was moderate — perhaps 15
pounds. If seating requires significantly more pressure, the operation damages the bullet’s fragile
pressure ring, bulging your groups. If the seating pressure is too light, he said you’re assured a
mediocre .250" rifle.
Virgil did not size his case necks. With about .00035" clearance on all sides between the
loaded round and chamber neck, the natural spring-back of the brass, in combination with his neck
preparation, correctly gripped the bullets. Some other warehouse shooters, including T.J. Jackson,
followed the same practice.
Cases, however, did wear out. Virgil estimated that a case would no longer grip and “snap” to
his satisfaction when it had been recycled 20 to 25 times. It was then discarded.
What about barrel life? In the warehouse, more than anywhere else, it could be accurately
gauged, because even a tiny loosening of group size would be detected. From his experiences and those
of others, Virgil estimated that stainless steel barrels chambered for the common .22 and 6mm
benchrest cartridges are pretty well over the hill at 1,000 rounds. But the finest accuracy sharpness of a
barrel departs much sooner. Noticeable deterioration may begin at about 700 rounds. He admitted
these figures could vary widely for obvious reasons reflecting barrel care, cleaning technique and
cartridge velocity levels.
When a shooter showed up at the Houston Warehouse with a really sick rifle, most often there
were no miracle cures. Already, the experienced shooters who came there had pretty much worked out
the best loads. Once scope problems had been eliminated, changing powder, bullet seating depth and
other factors usually didn’t improve things greatly. Only if a rifle arrived shooting in the mid-teens or
less did it have the potential of tuning down into the zeroes.
“If a gun was shooting one .250" group and then a .350",” Virgil said, “usually we couldn’t
help things much. Typically these guns would put three or four bullets in one hole and have the rest
hanging out.” These were the rifles that often were reworked and then brought back for another round
in the warehouse.
Interestingly, a rifle — whether it performs well or horribly — shoots in predictable patterns.
In his PS writings, T.J. Jackson observed that in the warehouse an excellent rifle would shoot the same
size and shape group time after time. But if you changed anything, such as bullet seating, the size of
the group or the shape or both would change. Virgil certainly agreed and added that with a truly flawed
rifle he could call every shot, whether left, right, down or up, before he nudged the trigger “The gun
follows a pattern every time,” he noted. “It shoots the same group in the same order according to the
cleanliness of the barrel.” In other words, the predictability applied only when the rifle was cleaned
between groups.
Virgil pointed out that one of the problems with the 4198 powder used in his highly accurate
22PPC was that it burned dirty. In warehouse shooting, when he was in hot pursuit of zeroes groups,
he cleaned his barrel with a bronze brush and solvent after every six shots — one fouler and one
group.
But at regular intervals the barrel had to undergo a scrubbing with J-B compound to remove
solvent-resistant fouling 3" to 4" up from the chamber. Although the fouling couldn’t be seen with the
unaided eye, Virgil could feel it with the cleaning rod. With the constriction constantly controlled, the
rifle would maintain its keen standard of accuracy. Virgil would have preferred H322 because it was
the cleanest-burning powder he tried in the 22PPC. Unfortunately, the rifle was uncooperative.
Rumors have persisted for years that some rifles shoot proportionally better at 200 yards than
100 yards, or vice versa. Virgil files that one under “occultism”. His experience in the warehouse was,
if a rifle was shooting a consistent .100" at 100 yards, it shot a consistent .200" at 200 yards. He
admitted, however, that his knowledge here is limited, because in the warehouse they rarely fired at
200 and 300 yards.
Virgil absorbed a wealth of information from the experienced shooters who visited the
warehouse. Don Geraci introduced him to IMR4198. Harold Broughton referred him to Wilbur
Cooper. John Jones and Henry Christman instructed him in the proper shooting technique. And there
were many other valuable lessons from perhaps the most knowledgeable people in the sport.
But no bit of information was, Virgil believes, more valuable than a little advice Jim Gilmore
passed along. Jim said a barrel MUST be 21 3/4” long for optimum accuracy. That precise length, he
stated, sets up a vibration pattern that duplicates well from shot to shot. Virgil faithfully followed that
advice on his guns.
Anyone who strictly observes the 21 3/4" doctrine will screw off a failing barrel of that length
and run a new one under it. Rechambering and rethreading, in order to achieve more pristine lands just
forward of the throat, shortens the barrel. Shorten the barrel, spoil the magic length.
Through the years, the Houston Warehouse shooters were able to rate the relative accuracy of
the various benchrest calibers — .22, 6mm and .30. In the perfect conditions of the warehouse, the
.22’s outshot them all, followed closely by the 6mm’s. The .308 calibers were a not-too-distant third.
The most accurate .30 caliber ever to find its way into the warehouse also belonged to Virgil. The
rifle, built around a Shilen DGA action with McMillan barrel, shot consistently within a few
thousandths of .100". The barrel length? You guessed it: 21 3/4".
During the six years the Houston Warehouse was in use, less than thirty shooters were invited
there. Part of the reason for such a small roster of participants was the sheer complications of the
situation. First, there was no way Virgil could allow people to come and go as they wished. The
warehouse was leased out and filled with thousands of dollars worth of materials belonging to someone
else. Then there were always the liability and insurance problems associated with the risks of firearms
use.
There also was a ticklish problem concerning the legalities of shooting there. Technically it
was against the law, because the warehouse was within the city limits of Houston. When the police
knocked on the door — and they did regularly in response to the noise of gunshots — Virgil was often
left with some heavy-duty explaining to do. Consequently, of necessity he had to be there any time the
warehouse was in use.
To further complicate matters, preparing the range for shooting and then putting everything
away was a laborious and time-consuming task, and the shooting itself consumed many hours. Since
things usually began late at night, a typical shooting session usually put Virgil home about the time his
alarm clock went off.
But frankly, Virgil also is a direct and unpretentious man who expects more honesty and
integrity from his acquaintances than most of us. If he had reason to dislike or distrust a fellow
shooter, that individual was not going to shoot in the warehouse. And that was that.
Of the superb shooters Virgil watched while he was shooting competitively, he rates Ron
Prachyl of Dallas as the most gifted. “Ron is a real shooter, not a warehouse shooter,” he pointed out.
“If Ron had owned my rifle, he would never have lost any match of any type.”
If, by the preceding statement, Virgil is suggesting that his own accomplishments and abilities
are somehow less than outside shooters, the obvious must be stated. In the warehouse, not even the best
competitive shooters in benchrest approached what Virgil was routinely able to do. His long,
consecutive strings of zero-level groups, fired over a period of years and witnessed by other shooters,
stand alone. Had he pursued competitive shooting with the same dedication and fierce concentration,
undoubtedly his accomplishments outside would have been as impressive.
Years of warehouse shooting till the small hours, punctuated by occasional competition, finally
took their toll. Although he won matches at Tomball, Lafayette, Lake Charles, New Braunfels, Austin
and Knoxville, Virgil eventually confronted the fact that the shooting that used to be such fun had
become work. He was burned out. Worse, he found himself habitually grieving over several
humiliating encounters with the shooting conditions at Midland. He gave his beloved 22PPC to Ralph
Council and slammed the warehouse doors to shooting. He didn’t even save any of the remarkable
targets.
The keys to the Houston Warehouse still jingle invitingly in Virgil’s pocket. The bench, target
holder and all-important fan are still there, collecting dust. But although the warehouse stands in
readiness, Virgil has no intentions of ever firing there again. That’s not to say, however, that he’s
through with shooting. Now and then he stokes up his Shilen-built .30-06, and on his backyard range
near Palestine, Texas, fires three shots into an admittedly larger hole than he once was accustomed.
Then he goes on to other things, and there’s a wide selection of these. Even though he’s officially
retired, Virgil defines “retirement” as working harder than he ever has at the things he loves to do.
That includes his present avocation, raising race horses.
As Virgil was voicing concern over a sick cow at home and the dangerous “killer” horse he
regretted having to sell, a customer opened the door of Ed Shilen’s office and asked where Ed was.
Virgil replied that Ed had left for a local bar and probably would be there all evening. This
less-than-accurate answer obviously satisfied the man. As he nodded knowingly and closed the door,
Virgil glanced at his watch and jumped to his feet. He had scheduled this to be only a two-hour
interview, and three hours had passed. He had pressing matters back at the house.
As he walked away, I had one final question. “Virgil,” I called as he opened the door, “was
there a secret you did NOT tell me?”
That stopped him in mid-stride. He stared at me for a few seconds, then broke into a broad
smile. “I didn’t tell you about how I finally got my 22PPC to arc.”
“Arc?” I responded dully.
“Arc,” he repeated. “There was one final thing I discovered late in the game. It had the rifle
down to a consistent .025"in the warehouse.”
I felt the sweat pop out on my brow. Now, it was me who did the staring. “Well, are you
going to tell me what it is?” I finally managed to ask in my most persuasive, bordering-on-begging
tone of voice
“It was in the preparation of the brass,” he said simply, then turned and walked away.
Now, if my high school math hasn’t failed me again, the man just said he had suddenly
trimmed those huge, gaping .035" groups by about one-third!
On a quiet night, when your annoying neighbor has borrowed your latest issue of Precision
Shooting you haven’t read, and there’s nothing but reruns on the tube, that parting shot from Virgil
King ought to give you something to think about.
