This site is for and about accurate shooters. So today we feature the short-range group Benchrest game, where it’s all about shooting tiny groups in the ones and even “zeros”. Seeing the tiny groups 6 PPC aces produce, it’s easy to think the precision is all about the equipment. But there is a lot more involved. A talented human still has to watch the flags, run the gun properly, and tune his loads for the conditions. Here are some tips from one of the world’s best benchresters, Charles Huckeba.
Texan Charles Huckeba was the top individual shooter at the 2013 World Benchrest Championships (WBC) held near Sydney Australia in October 2013. In this video, 2013 WBC Two-Gun Overall winner Charles shoots a 1/8th MOA group at 200 yards — “a little bitty dot” as a fellow Team USA shooter observes. That’s impressive. If you can describe Huckeba’s style in a nutshell it would be “smooth, consistent, and rapid but not hurried”.
Charles also employed some unusual hardware. In the video, take a close look at the joystick on the Farley Coaxial front rest. There’s no knob at the end. In its place is a small, wood ammo caddy. Charles removed the standard knob from the handle of his Farley rest and replaced it with a home-made wood block that holds cartridges for the record target. The 10.5-lb Light Varmint rifle is chambered in 6PPC with a BAT Machine Action and a composite wood and carbon-fiber stock.

Analyzing the Fine Points — What Makes Huckeba So Good
Short-range benchrest shooter Boyd Allen saw some interesting things in Huckeba’s WBC performance, as captured on video. Boyd noticed Huckeba’s smooth gun-handling and efficient loading. But Boyd also spied some interesting equipment, including an innovative joystick “handle-caddy”.
1. Low Friction Bags — When Huckeba slid his rifle, there was very little apparent friction. The front bag features the new 3M material (ScotchLite) on the sliding surfaces. The rear Protektor bag has ears of the same low-friction material.
2. Pause Before Chambering — While he was watching the flags and deciding when to start firing, Charles kept his first round in the action, but out of the barrel’s chamber, probably so as not to heat the cartridge and change the round’s point of impact.
3. Ammo Caddy on Joystick Arm – Charles shoots a Right Bolt/Left Port action, so he pulls his rounds with his left hand. Note that Huckeba’s record rounds rest in a small, wood ammo caddy attached to the end of the joystick shaft. Look carefully, you’ll see the wood ammo block in place of the normal black ball at the end of the joystick. That allows Charles to pull shots with the absolute minimum of hand movement. Ingenious! Huckeba is very fast, with a great economy of motion. I believe that because his ammo was literally at hand, Charles was better able to keep his focus on aiming and the flags.
4. Smooth-Cycling BAT Action — Note how smoothly Huckeba’s action operates. When Charles lifts the bolt handle (to extract a round and cock the firing pin), this does not disturb the rifle. Likewise, as he closes the bolt, the gun doesn’t wobble. The smooth action allows Charles to hold point of aim even when shooting relatively quickly. Huckeba’s BAT action is chrome-moly steel. Some shooters believe this metal makes for a smoother action than stainless steel or aluminum.
5. Long-Wheelbase Stock — The wood and carbon fiber stock is light, long, and stiff. Yet, importantly, the stock is also well-damped. The longer-than-average stock length (with extended forearm) seems to help the gun track well without jumping or rocking. The longer forearm allows a longer “wheelbase”, effectively shifting the weight distribution rearward (less weight on the front, more weight on the rear). This places a greater share of the gun’s weight on the rear bag, as compared to a more conventional benchrest stock. Huckeba’s stock, built by Bob Scoville, is at the cutting edge of short-range benchrest design. Its light-weight balsa wood and carbon fiber construction provides a combination of stiffness and vibration damping that allows its relatively long fore-end to be fully utilized to increase the weight on the rear bag (always an issue with 10.5-pound rifles).
To learn more about this benchrest stock design, read the comments by stock-builder Bob Scoville in our PPC with Pedigree story in our Gun of the Week Archives. Bob observed:
“There is a lot more to the structure of the stocks than meets the eye. The carbon fiber skin with which I cover the stocks creates a light, tough exterior surface. However, this contributes very little to the overall performance of the stocks. The real strength and stiffness is the result of an internal beam utilizing balsa core/carbon fiber technology.
This type construction can be found in aircraft, race cars, powerboats, and sailboats. It is interesting to note, balsa has the highest strength to weight ratio of all woods and carbon fiber is one of the lowest stretch (modulus of elasticity) relative to weight of all materials. The marriage of these two materials is common in the high-performance world. Additionally, balsa is used commercially for vibration dampening and sound reduction.”

Forest of Windflags at World Benchrest Championships in France in 2011
There’s a simple, inexpensive “miracle device” that can cut your groups in half. If you’re not using this device, you’re giving away accuracy. The “miracle device” to which we refer is a simple wind indicator aka “windflag”. Using windflags may actually improve your accuracy on target much more than weighing charges to the kernel, or spending your life savings on the “latest and greatest” hardware.
Remarkably, many shooters who spend $3000.00 or more on a precision rifle never bother to set up windflags, or even simple wood stakes with some ribbon to show the wind. Whether you’re a competitive shooter, a varminter, or someone who just likes to punch small groups, you should always take a set of windflags (or some kind of wind indicators) when you head to the range or the prairie dog fields. And yes, if you pay attention to your windflags, you can easily cut your group sizes in half. Here’s proof…
Miss a 5 mph Shift and You Could DOUBLE Your Group Size
The table below records the effect of a 5 mph crosswind at 100, 200, and 300 yards. You may be thinking, “well, I’d never miss a 5 mph let-off.” Consider this — if a gentle 2.5 mph breeze switches from 3 o’clock (R to L) to 9 o’clock (L to R), you’ve just missed a 5 mph net change. What will that do to your group? Look at the table to find out.
Values from Point Blank Ballistics software for 500′ elevation and 70° temperature.
Imagine you have a 6mm rifle that shoots half-MOA consistently in no-wind conditions. What happens if you miss a 5 mph shift (the equivalent of a full reversal of a 2.5 mph crosswind)? Well, if you’re shooting a 68gr flatbase bullet, your shot is going to move about 0.49″ at 100 yards, nearly doubling your group size. With a 105gr VLD, the bullet moves 0.28″ … not as much to be sure, but still enough to ruin a nice small group. What about an AR15, shooting 55-grainers at 3300 fps? Well, if you miss that same 5 mph shift, your low-BC bullet moves 0.68″. That pushes a half-inch group well past an inch. If you had a half-MOA capable AR, now it’s shooting worse than 1 MOA. And, as you might expect, the wind effects at 200 and 300 yards are even more dramatic. If you miss a 5 mph, full-value wind change, your 300-yard group could easily expand by 2.5″ or more.
If you’ve already invested in an accurate rifle with a good barrel, you are “throwing away” accuracy if you shoot without wind flags. You can spend a ton of money on fancy shooting accessories (such as expensive front rests and spotting scopes) but, dollar for dollar, nothing will potentially improve your shooting as much as a good set of windflags, used religiously.
Every summer weekend, there are probably 400 or more club “fun matches” conducted around the country. One of the good things about these club shoots is that you don’t have to spend a fortune on equipment to have fun. But we’ve seen that many club shooters handicap themselves with a few common equipment oversights or lack of attention to detail while reloading. Here are SIX TIPS that can help you avoid these common mistakes, and build more accurate ammo for your club matches.
1. Align Front Rest and Rear Bags. We see many shooters whose rear bag is angled left or right relative to the bore axis. This can happen when you rush your set-up. But even if you set the gun up carefully, the rear bag can twist due to recoil or the way your arm contacts the bag. After every shot, make sure your rear bag is aligned properly (this is especially important for bag squeezers who may actually pull the bag out of alignment as they squeeze).
Forum member ArtB adds: “To align my front rest and rear bag with the target, I use an old golf club shaft. I run it from my front rest stop through a line that crosses over my speed screw and into the slot between the two ears. I stand behind that set-up and make sure I see a straight line pointing at the target. I also tape a spot on the golf shaft that indicates how far the back end of the rear bag should be placed from the front rest stop. If you don’t have a golf shaft, use a wood dowel.
2. Avoid Contact Interference. We see three common kinds of contact or mechanical interference that can really hurt accuracy. First, if your stock has front and/or rear sling swivels make sure these do NOT contact the front or rear bags at any point of the gun’s travel. When a sling swivel digs into the front bag that can cause a shot to pop high or low. To avoid this, reposition the rifle so the swivels don’t contact the bags or simply remove the swivels before your match. Second, watch out for the rear of the stock grip area. Make sure this is not resting on the bag as you fire and that it can’t come back to contact the bag during recoil. That lip or edge at the bottom of the grip can cause problems when it contacts the rear bag. Third, watch out for the stud or arm on the front rest that limits forward stock travel. With some rests this is high enough that it can actually contact the barrel. We encountered one shooter recently who was complaining about “vertical flyers” during his match. It turns out his barrel was actually hitting the front stop! With most front rests you can either lower the stop or twist the arm to the left or right so it won’t contact the barrel.
3. Weigh Your Charges — Every One. This may sound obvious, but many folks still rely on a powder measure. Yes we know that most short-range BR shooters throw their charges without weighing, but if you’re going to pre-load for a club match there is no reason NOT to weigh your charges. You may be surprised at how inconsistent your powder measure actually is. One of our testers was recently throwing H4198 charges from a Harrell’s measure for his 30BR. Each charge was then weighed twice with a Denver Instrument lab scale. Our tester found that thrown charges varied by up to 0.7 grains! And that’s with a premium measure.
4. Measure Your Loaded Ammo — After Bullet Seating. Even if you’ve checked your brass and bullets prior to assembling your ammo, we recommend that you weigh your loaded rounds and measure them from base of case to bullet ogive using a comparator. If you find a round that is “way off” in weight or more than .005″ off your intended base to ogive length, set it aside and use that round for a fouler. (Note: if the weight is off by more than 6 or 7 grains you may want to disassemble the round and check your powder charge.) With premium, pre-sorted bullets, we’ve found that we can keep 95% of loaded rounds within a range of .002″, measuring from base (of case) to ogive. Now, with some lots of bullets, you just can’t keep things within .002″, but you should still measure each loaded match round to ensure you don’t have some cases that are way too short or way too long.
5. Check Your Fasteners. Before a match you need to double-check your scope rings or iron sight mounts to ensure everything is tight. Likewise, you should check the tension on the screws/bolts that hold the action in place. Even on a low-recoiling rimfire rifle, action screws or scope rings can come loose during normal firing.
6. Make a Checklist and Pack the Night Before. Ever drive 50 miles to a match then discover you have the wrong ammo or that you forgot your bolt? Well, mistakes like that happen to the best of us. You can avoid these oversights (and reduce stress at matches) by making a checklist of all the stuff you need. Organize your firearms, range kit, ammo box, and shooting accessories the night before the match. And, like a good Boy Scout, “be prepared”. Bring a jacket and hat if it might be cold. If you have windflags, bring them (even if you’re not sure the rules allow them). Bring spare batteries, and it’s wise to bring a spare rifle and ammo for it. If you have just one gun, a simple mechanical breakdown (such as a broken firing pin) can ruin your whole weekend.

With the Berger Southwest Nationals (SWN) taking place this week in Phoenix, we are reprising this discussing of rear bag designs and fill levels. By “tuning” your rear bag you can reduce hop on shot-firing and help your rifle track better. All that can translate to better scores, particularly with large-caliber rifles.
Tuning Your Rear Sand Bags
Over the years, noted gunsmith and a Benchrest Hall-of-Fame inductee Thomas ‘Speedy’ Gonzalez has learned a few things about “tuning” rear sandbags for best performance. On his Facebook page, Speedy recently discussed how sand bag fill levels (hard vs. soft) can affect accuracy. Speedy says you don’t want to have both your front and rear sandbags filled up ultra-hard. One or the other bag needs to have some “give” to provide a shock-absorbing function (and prevent stock jump). And you want to tune your fill arrangements to match your shooting style. Free recoil shooters may need a different fill levels than bag squeezers (who a softer bag but harder ears).
SAND BAGS & HOW TO FILL THEMby Speedy Gonzalez
I was asked several times by competitors at the S.O.A. Matches and F-Class Nationals as to how I fill my sand bags for benchrest competition. Here is a copy of a reply I gave several years ago:
Back in the old days, Pat McMillan told me: “You can not have two bags filled so hard that you gun bounces on them in the process of firing round at your target, especially if you have a rig with a very flexible stock. The bags must be set up in a manner for them to absorb the initial shock of the firing pin moving forward and igniting the primer.
Then [they must] maintain their shape and absorb the second shock wave as well the rearward thrust and torque of the rifle. What happens to the rifle when this is not done? Well let me tell you. The rifles have a very bad tendency to jump and roll in the bags. This causes many of those wild, lost shots that one can’t explain.”
Here’s some Good General Advice for Bag Set-up:
1. You should not have TWO hard bags [i.e. both front AND rear] in your set-up.
2. Heavy sand magnifies these phenomena.
3. If you are a bag squeezer, pack ears hard and leave bag pliable enough to squeeze for the movement required. You may pack front bag as hard as rules permit.
4. Free recoil shooters pack both bags firm, but not so hard as to allow stock jump. Especially if you have a stock with a very flexible forearm.
5. We use play-ground sand, also know as silica sand. I sift mine to get any large impurities out then mix it with 25% to 50% with Harts parakeet gravel to the desired hardness that I am looking for. The bird gravel keeps the sand from packing itself into that solid as a brick state.
Speaking of bricks — another thing that happens when shooters employ that heavy zircon sand is the ears form a low spot under them from recoil and then tend to rock back and forth with the rifle causing many low shots to crop up. Edgewood makes an Edgewood/Speedy rear bag specially reinforced under the ears to eliminate this scenario.
General Thoughts about Bag Construction and Ear Materials
I do not like the solid double-stitched leather bottoms. While this seems like a good idea, I see more shooters have problems because of them. They tend to slide around the bench and or slide with the rifle on recoil. The standard Protektor with Cordura rabbit ears and an Otto ring bag with a Cordura front would be what I would suggest to the new shooter or one of the Edgewood / Speedy rear bags, these mimic the “Donut” and feature a ring of leather around the bottom circumference that keep the bottom from rocking on the bench or ground[.]
One last note –If you use the Cordura bags, keep them sprayed with a good silicon spray or “Rain-Ex”. This keeps them from getting sticky. — Speedy

Barrel-maker Dan Lilja’s website has an excellent FAQ page that contains a wealth of useful information. On the Lilja FAQ Page as you’ll find informed answers to many commonly-asked questions. For example, Dan’s FAQ addresses the question of barrel life. Dan looks at factors that affect barrel longevity, and provides some predictions for barrel life, based on caliber, chambering, and intended use.
NOTE: This article was very well-received when it was first published last year. We are reprising it for the benefit of readers who missed it the first time.
Dan cautions that “Predicting barrel life is a complicated, highly variable subject — there is not a simple answer. Signs of accurate barrel life on the wane are increased copper fouling, lengthened throat depth, and decreased accuracy.” Dan also notes that barrels can wear prematurely from heat: “Any fast varmint-type cartridge can burn out a barrel in just a few hundred rounds if those rounds are shot one after another without letting the barrel cool between groups.”
Q. What Barrel Life, in number of rounds fired, can I expect from my new barrel?
A: That is a good question, asked often by our customers. But again there is not a simple answer. In my opinion there are two distinct types of barrel life. Accurate barrel life is probably the type most of us are referencing when we ask the question. But there is also absolute barrel life too. That is the point where a barrel will no longer stabilize a bullet and accuracy is wild. The benchrest shooter and to a lesser extent other target shooters are looking at accurate barrel life only when asking this question. To a benchrest shooter firing in matches where group size is the only measure of precision, accuracy is everything. But to a score shooter firing at a target, or bull, that is larger than the potential group size of the rifle, it is less important. And to the varmint hunter shooting prairie dog-size animals, the difference between a .25 MOA rifle or one that has dropped in accuracy to .5 MOA may not be noticeable in the field.
The big enemy to barrel life is heat. A barrel looses most of its accuracy due to erosion of the throat area of the barrel. Although wear on the crown from cleaning can cause problems too. The throat erosion is accelerated by heat. Any fast varmint-type cartridge can burn out a barrel in just a few hundred rounds if those rounds are shot one after another without letting the barrel cool between groups. A cartridge burning less powder will last longer or increasing the bore size for a given powder volume helps too. For example a .243 Winchester and a .308 Winchester both are based on the same case but the .308 will last longer because it has a larger bore.
And stainless steel barrels will last longer than chrome-moly barrels. This is due to the ability of stainless steel to resist heat erosion better than the chrome-moly steel.
Barrel Life Guidelines by Caliber and Cartridge Type
As a very rough rule of thumb I would say that with cartridges of .222 Remington size you could expect an accurate barrel life of 3000-4000 rounds. And varmint-type accuracy should be quite a bit longer than this.
For medium-size cartridges, such as the .308 Winchester, 7×57 and even the 25-06, 2000-3000 rounds of accurate life is reasonable.
Hot .224 caliber-type cartridges will not do as well, and 1000-2500 rounds is to be expected.
Bigger magnum hunting-type rounds will shoot from 1500-3000 accurate rounds. But the bigger 30-378 Weatherby types won’t do as well, being closer to the 1500-round figure.
These numbers are based on the use of stainless steel barrels. For chrome-moly barrels I would reduce these by roughly 20%.
The .17 and .50 calibers are rules unto themselves and I’m pressed to predict a figure.
The best life can be expected from the 22 long rifle (.22 LR) barrels with 5000-10,000 accurate rounds to be expected. We have in our shop one our drop-in Anschutz barrels that has 200,000 rounds through it and the shooter, a competitive small-bore shooter reported that it had just quit shooting.
Remember that predicting barrel life is a complicated, highly variable subject. You are the best judge of this with your particular barrel. Signs of accurate barrel life on the wane are increased copper fouling, lengthened throat depth, and decreased accuracy.
Benchrest Barrel Life — You May Be Surprised
I thought it might be interesting to point out a few exceptional Aggregates that I’ve fired with 6PPC benchrest rifles with barrels that had thousands of rounds through them. I know benchrest shooters that would never fire barrels with over 1500 shots fired in them in registered benchrest matches.
I fired my smallest 100-yard 5-shot Aggregate ever in 1992 at a registered benchrest match in Lewiston, Idaho. It was a .1558″ aggregate fired in the Heavy Varmint class. And that barrel had about 2100 rounds through it at the time.
Another good aggregate was fired at the 1997 NBRSA Nationals in Phoenix, Arizona during the 200-yard Light Varmint event. I placed second at this yardage with a 6PPC barrel that had over 2700 rounds through it at the time. I retired this barrel after that match because it had started to copper-foul quite a bit. But accuracy was still good.

Sam (L.E.) Wilson actively competed in benchrest matches until he passed. He’s shown here with an Unlimited benchrest rifle of his own design.
If you’ve used hand dies with an arbor press, chances are you’ve seen the L.E. Wilson company name. You may not know that the founder of L.E. Wilson Inc. was an avid benchrest competitor who pioneered many of the precision reloading methods we used today. Known as “Sam” to his friends, L.E. Wilson was one of the great accuracy pioneers who collected many trophies for match victories during his long shooting career.
The photo above shows Sam (foreground) with all of his children at a shoot. Behind Sam are Jim, Jack and Mary, shooting in the Unlimited Class. What do they say — “the family that plays together stays together”? Note the long, externally-adjusted scopes being used. Learn more about Sam (L.E.) Wilson and his company on the L.E. Wilson Inc. Facebook Page.
Unlimited Class was Sam’s favorite discipline, because in the “good old days” top competitors normally would craft both the rifle and the front/rear rests. This rewarded Sam’s ingenuity and machining/fabrication skills. In the “build-it-yourself” era, one couldn’t just order up an unlimited rail gun on the internet. How times have changed…

We love it when family members shoot together. It’s a great way to pass knowledge from generation to generation. Last week we featured a 10-year old boy, his father, and his grandfather who all shot a match together. Three generations! That was the young man’s first benchrest shooting match. Story HERE.
This week we are showcasing the Murdica clan. Our friend Lou Murdica was in Coastal Southern California this week. Grandpa Lou had taken two of his granddaughters to SoCal to enjoy the beach, and to shoot an F-Class match at Camp Pendleton.
Lou reports: “I took my two granddaughters (ages 12 and 14) to shoot their first-ever F-Class match! we went to Camp Pendleton yesterday and shot the 1000-yard match. This was the first time the girls had ever shot on the ground. They made me proud!”
Both girls shot very well as you can see from these targets. Angelina used a .284 Win rifle, while Bella used Lou’s 6.5×55 Improved. Both are top-level F-Open rigs. Lou said conditions were fairly challenging — with about 4 MINUTES of wind.
There were some interesting comments from Lou’s Facebook Friends:
“Lou you best quit shooting now while you can still beat them!” — Larry Bartholome (Editor: Larry B. is a past F-Class National Champion)
“Wow — just 1 point separation for the girls. Keep em in the ‘X’ girls! Good job!” — Anthony Smith
“Yea for Bella and Angelina. Such a proud grandpa!” — Kate White

FREE Bench Plans on the Web
Building your own portable shooting bench is a great do-it-yourself project. You can build a sturdy bench for well under $100 in materials. Compare that to some deluxe factory-built benches which may cost $600.00 or more. You’ll find a wide assortment of home-built shooting bench designs (both portable and fixed) on the internet. Renovation Headquarters has links to FREE Plans and building instructions for fourteen (14) different shooting benches. There are all-wood shooting bench designs as well as benches that combine a wood top with a metal sub-frame or legs.
Heavy Wood Bench That Converts to Three Sections for Transport
In addition to the fourteen benches mentioned above, here is an interesting break-down bench design. Call it a “semi-portable” bench. The legs and frame are made from stout 4×4 post segments so the bench is fairly heavy. However, this bench can break down into three (3) sections for easier transport to and from the range. Dado-cut channels assure proper top alignment. This might be a good choice if you plan a multi-day excursion to a location without fixed benches. This three-leg bench design can be made from easy-to-locate materials. Note: The dimensions of this bench are are larger than typical fixed benches to accommodate 50 BMGs and other big rifles. CLICK HERE for more details.
Have a good look at the photos below — this may be one of the most noteworthy target strings we’ve ever published. What you can see is the effect of barrel tuner position on point of impact (POI). You can clearly see that the tuner position alters the up/down POI location in a predictable fashion.
This remarkable 15-shot sequence was shot by French benchrester Pascal Fischbach using his 6 PPC fitted with a CG (Carlito Gonzales) action and a Bukys barrel tuner.
Pascal reports: “After [bullet] seating and load validation, I put the Bukys tuner on, screwing it out 10 turns. According to Carlito, the CG’s super stiff action-to-barrel fit gives a faster vibration modulus that is detrimental below 10 turns [position of the tuner].” Pascal’s procedure was to screw out the tuner 1/4 turn progressively from one shot to the next. He shot one bullet at each tuner position, with a total of 15 shots.
Left Half of Target Strip (shots with 1/4 rotation change of tuner in sequence)
Right Half of Target Strip (shots with 1/4 rotation change of tuner in sequence)
Pascal observed: “Note the point of impact displacement [from shot to shot] tracks clearly along a sinusoide (sine wave curve).” This is indeed notable and significant! This shows how the tuner’s ability to change barrel harmonics can alter the position of the muzzle as each bullet exits, resulting in a higher or lower POI. Pascal sent his results to Carlito Gonzales in Argentina for analysis.
Pascal poses this question to readers: “Guess which three positions Carlito recommends to try?”
Editor’s Note: While this target sequence clearly shows how tuner position can alter bullet point of impact, this, by itself, does not tell us which tuner position(s) are best for accuracy. That will require further multi-shot group testing, involving careful experimentation with tuner position (and powder charge weights). But for those folks who doubt that a tuner can make a difference on a short, fat barrel, just take another look at the photos. The up/down changes are undeniable, and noteworthy in the wave pattern they follow.
Shooting Set-up and Test Conditions:
Pascal did this test at an outdoor range under very good conditions: “This was shot at my home range, outdoors, with four Smiley flags. The range is a narrow cut in high woods. Wind was consistent with readable flags. I started testing the tuner from 10 turns out and on to 15. I recently… found a sweet spot very close to the rearmost position of the tuner, so the rigidity provided by this super long tenon (just short of 70mm) was not a reason to overlook the recommended Bukys tuning procedure.”

Five targets, each with FIVE shots in essentially one hole. The events of this story happened two years ago. We are reprising our report because this five-target Aggregate arguably represents the most impressive feat of 100-yard accuracy in the history of marksmanship on this planet.
Check out those five targets. The Aggregate (average) of all five targets is a tiny 0.0840 inches! These were shot by Gary Ocock at 100 yards in a California benchrest match on August 6, 2017. Though Gary’s 0.0840 Agg beats existing records, this was not a “sanctioned” match, so Gary’s killer Agg will NOT be submitted for IBS or NBRSA records. So, sadly, the Agg won’t appear in the record books, but this remains a spectacular, verified feat of rifle accuracy, accomplished in competition.
The argument can be made that this is the Most Accurate Gun Ever Built. As far as we can determine, no one has ever shot a smaller 5-target Agg anywhere, at any time.
The Unlimited Benchrest Record That Will Never Be (Official)
Report by Boyd Allen
Gary Ocock’s stunning unlimited Aggregate is beyond amazing. That’s an average of five, 5-shot groups of .0840. Shot under sanctioned match rules, but at an unsanctioned 100-yard fun match, this Aggregate is well under the current 100-yard official records of the IBS (.1386), and the NBRSA (.1242). The fourth of the five groups measured a minuscule .018, less than half the size of the existing NBRSA Unlimited record of .049 (also shot by Gary). Check it out:
When the top 15 shooters all post teen Aggs, conditions must be pretty favorable. However there were some light switchy winds — Gary said that he shot better in the left to right condition.
GUN SPECIFICATIONS
Ocock’s red Jay Young Unlimited Railgun features one major difference from Young’s typical Railgun designs. The bottom of the barrel block is integral with the top (moving part), of the gun. The barrel is Ocock’s usual 1:13.5″-twist Krieger chambered for the 6 PPC. The BAT Neuvo action* is unusual in that its lugs are horizontal at lock-up instead of the usual vertical. With horizontal lugs, both lugs maintain contact with their abutments when the action is cocked. In the more normal configuration when cocked the top lug is forced off of its seat by a combination of the angle of the trigger cocking piece interface, the pressure of the striker spring, and bolt clearance at the rear of the action.
LOAD SPECIFICATIONS
Gary shot this remarkable Agg with well-used brass, Vihtavuori N133 powder, and self-made 66gr BT bullets** seated at “jam”. This amazing Agg was shot on the second day of a 2-day Unlimited Benchrest match. On Day 1 Gary had experimented with various loads using both surplus IMR 8208 and Vihtavuori N133, but was not satisfied with the results. For his first group on Day 2, Gary tried a light load of N133. After seeing the result, however, he decided to go to the other extreme — a super stout N133 load — with the same powder. As you can see, Gary’s willingness to experiment paid off.
Notably, Gary used light neck tension. Ocock found that for these bullets and this barrel, light neck tension worked best (contrary to “normal” N133 benchrest practice). Ocock used a bushing that only produces .001″ difference between the diameters of sized and loaded case necks.
Comment on Ocock’s Achievement
Congratulations to Gary Ocock for superb shooting (and smart loading). Even though the match was not sanctioned (so the Agg will never be a record), Ocock has raised the bar very high, and given us a new standard of ultimate accuracy.
Though this 0.0840 Aggregate and 0.018 group will never go into the record group, they are still noteworthy. There’s virtually no doubt that they would have survived inspection by any record committee. Except for the lack of fixed backers, an IBS requirement (for detecting cross-fires), all other conditions were met for an officially-sanctioned match.
*The new BAT Neuvo actions are the result of a collaboration between Dwight Scott, and Bruce Thom, featuring Dwight’s ideas and BAT’s proven manufacturing expertise.
** Ocock shot his own, boat-tail match bullets, made with George Ulrich-crafted dies using Hood cores. Although he said that it had been a while since he had weighed any, his best guess was that they weigh something around 66.5 grains.

Want to shoot better scores at your next match? Here’s a smart, inexpensive do-it-yourself project from the good folks at Criterion Barrels. For less than one dollar in materials, in just a few minutes you can create a handy, effective mirage shield, custom-fitted to your favorite rifle.
All precision shooters should be familiar with mirage, a form of optical distortion caused primarily by variations in air temperature. Savvy shooters will use mirage as a valuable tool when gauging wind speed and direction. Natural mirage is unavoidable, but there are many techniques designed to limit its influence in long-range marksmanship.
A form of mirage can be produced by the barrel itself. Heat rising from the barrel may distort sight picture through your optics, leading to erratic results. Mirage caused by barrel heat can be reduced dramatically by a simple, light-weight mirage shield.
How to Make a Mirage Shield
A mirage shield is an extremely cost-effective way to eliminate a commonly-encountered problem. Making your own mirage shield is easy. Using old venetian blind strips and common household materials and tools, you can construct your own mirage shield for under one dollar.
Materials Required:
1. Vertical PVC Venetian blind panel
2. Three 1”x1” pieces adhesive-backed Velcro
3. Ruler or tape measure
4. Scissors or box cutter
5. Pencil or marker
1. Measure the distance from the end of the receiver or rail to the crown of the barrel.
2. Using a pencil and ruler, measure the same distance and mark an even line across the blind.
3. Cut across the line using scissors or a box cutter, shortening the blind to the required length. (Remember, measure twice, cut once!)
4. Expose the adhesive backing on the loop side of the Velcro. Center and apply the Velcro strips on the barrel at regular intervals.
5. Expose the adhesive backing of the fuzzy side of the Velcro.
6. Place the blind on the upper side of the barrel. Apply downward pressure. Once the Velcro has secured itself to the barrel, separate the two sides. Proceed to mold both sides of the Velcro to fit the contour of their respective surfaces.
7. Reaffix the blind. Barrel related mirage is now a thing of the past!
NOTE: You can attach the Velcro on the opposite side of the blind if you want the blind to curve upwards. Some folks thinks that aids barrel cooling — it’s worth a try.
How to Remove and Re-Attach the Mirage Shield
Removal of your mirage shield is accomplished by simply removing the blind. You can un-install the Velcro by pulling off the strips and then gently removing any adhesive residue left behind using an appropriate solvent. (Simple cooking oil may do the job.) Caution: With fine, high-polish blued barrels, test any solvent on a non-visible section of the barrel. Before storing the gun, re-oil the barrel to remove active solvents and residual fingerprints.

You don’t hear much about PacNor barrels in long-range competition, but FORUM member Wes J (aka P1ZombieKiller), proved that they can shoot “lights-out” in a rig assembled by a talented gunsmith. A few seasons back, Wes decided to upgrade a 6mmBR for mid-range benchrest and varmint matches. Wes tells us: “Since I restocked my 6BR … I have not had a chance to shoot it much since I have been playing the 100-200 game. I decided to take it out and do some playing at 500 yards. I have to give some serious props to my buddy (and fellow FORUM member) ‘PREACHER’ who did the chambering and barrel work for me. He can certainly make a gun shoot good. The barrel is a PacNor 1:8″ twist. My load was 105gr Berger VLDs pushed by 29.6 grains of Varget.” The five-round, 500-yard group shot by Wes J with his 6BR, measured just 1.240″, as measured by OnTarget software. Now that’s one accurate rig!
Five by Five — 5-Shot Group at 500 Yards, 1.240″, 0.237 MOA
This Editor knows something about the potential of a PacNor barrel. I have a 3-groove stainless PacNor SuperMatch on a Savage-actioned 6BR. This barrel shoots honest quarter-MOA in calm conditions, and it cleans up super-easy. The interior finish is so good, I’ve never had to brush the bore or use abrasives, and after 750 rounds it shoots as well as ever. I attribute the easy cleaning to the fact the lands in a PacNor 3-groove are wide and flat, so they are gentle on bullet jackets. I think accuracy is helped by the fact that my PacNor runs on the tight side (0.236 land dimension) with a good amount of choke. That works well with the 105gr Lapua Scenars and 103gr Spencers I like to shoot. You can read more about my rifle, nick-named the “Poor Man’s Hammer”, in this Feature Article from our archives. On one particularly calm day, in the hands of my friend (and ace trigger-puller) Joe Friedrich, the Poor Mans’ Hammer put 3 shots in under 0.200″ (measured center to center) at TWO Hundred yards. If you get a good one, PacNor three-grooves can definitely shoot.
Target Measurement with OnTarget Software
We used OnTarget software to measure the 5-shot group in the target above. This easy-to-use software is very repeatable, once you get a feel for plotting the shots. The latest On Target v2.25 Precision Calculator is FREE for a 15-day evaluation period. If you like it (and you will, trust us) there’s a modest $11.99 registration fee to activate the program. In addition to group size (in inches), OnTarget plots distance to aiming point, and the software automatically calculates the group’s vertical height, horizontal dispersion, average to center (ATC), and group size in MOA.
You can run a measurement on a scanned target or a photo of a target. You’ll need some known reference to set the scale correctly. The target above had a one-inch grid so it was easy to set the scale. Once you’ve set the scale and selected bullet diameter and target distance, you simply position the small circles over each bullet hole and the OnTarget software calculates everything automatically, displaying the data in a data box superimposed over the target image. To learn more about OnTarget Software, read AccurateShooter.com’s OnTarget Product Review. This article covers all the basics as well as some advanced “power user” tips. NOTE: Since the review was written, On Target has updated the software, and the free version now has a time limit.

Precision rifle shooters don’t have to hit a big-league fastball, or launch a top-fuel dragster in the blink of an eye. Nonetheless, reaction times are important in our sport — both for competitive shooters and hunters. Want to catch that prairie dog before he slips down his hole? You’ll need to be quick. Want to win at short-range benchrest? Then you’ll need to watch your windflags and respond quickly to a change. Miss a major wind-shift and you could ruin your whole weekend.
Here’s a fun test of reaction times from HumanBenchmark.com. The way it works is that, after clicking “Start”, you wait until the background color changes from red to green. The instant you see green, immediately click your mouse. The average (median) reaction time is 215 milliseconds.
Tips for Faster Times
Here are three tips to speed up your reaction times:
1) Respond to the color change, rather than wait to read “CLICK!”.
2) Try focusing at the corner of the colored box, rather than the center.
3) Have your index finger “poised and ready” over the left button–you can shave milliseconds by very slightly depressing the button before you actually click.

What components do world-class, short-range group benchrest shooters use? BAT actions, Krieger barrels, and Bix’n Andy triggers (and Jewells) are the components of choice. And barrel tuners are now widely used by the top shooters. As for powder, Vitavuori N133 is still the choice of virtually all top competitors. And yes the 6PPC definitely rules the roost. Every Top 20 shooter at the 2019 Super Shoot shot a 6PPC. Every one. Read on to learn more about the Top 20 Equipment used at this year’s Super Shoot.
We recently reviewed the Top 20 Equipment List for the 2019 Super Shoot at the Kelbly’s Range in Ohio. This Top 20 List reveals the gear choices for the 13.5-lb Heavy Varmint Class and the 10.5-lb Light Varmint/Sporter Class (20 entries for each division). Here are notable gear choices for Top 20 Competitors (both divisions) at the 2019 Super Shoot:
Actions: 14 of 20 HV and 16 of 20 LV/SP shooters used BAT actions. So there were 75% BATs for both classes combined. Barrels: 10 of 13 listed HV barrels and 9 of 12 listed LV/SP barrels were Kriegers. Overall, of the barrels identified in the Top 20 Equipment lists, 76% were Krieger. That’s dominance! [Note: We have been informed that entries with no barrel-maker listed may have been Bartlein barrels.] Triggers: Notably 10 of 20 HV triggers were Bix’n Andy — 50%. For the other class, 7 of 19 listed triggers were Bix ‘N Andy. All others were Jewells. Tuners: In HV Class, 12 of 20 shooters used tuners, mostly Bukys. 11 of 20 LV/SP shooters had tuners. Overall that is 57.5% tuner usage for both classes combined.
Cartridge: For both classes, every single Top 20 competitor shot the 6PPC. ‘Nuf said. Powders: 19 of 20 HV Shooters used Vihtavuori N133. Likewise 19 of 20 LV/SP shooters used VV N133, with one not reporting. That is total dominance for N133.
Bullets: There was a wide selection of bullets used in both classes. Custom bullets by “boutique” bullet makers were certainly favored by Top 20 shooters. Sta Moy 65s were popular, as were Hottenstein 68s and Bart’s bullets among others.

When a rifle isn’t shooting up to it’s potential, we need to ask: “Is it the gun or the shooter?” Having multiple shooters test the same rifle in the same conditions with the same load can be very revealing…
When developing a load for a new rifle, one can easily get consumed by all the potential variables — charge weight, seating depth, neck tension, primer options, neck lube, and so on. When you’re fully focused on loading variables, and the results on the target are disappointing, you may quickly assume you need to change your load. But we learned that sometimes the load is just fine — the problem is the trigger puller, or the set-up on the bench.
Here’s an example. A while back we tested two new Savage F-Class rifles, both chambered in 6mmBR. Initial results were promising, but not great — one gun’s owner was getting round groups with shots distributed at 10 o’clock, 2 o’clock, 5 o’clock, 8 o’clock, and none were touching. We could have concluded that the load was no good. But then another shooter sat down behind the rifle and put the next two shots, identical load, through the same hole. Shooter #2 eventually produced a 6-shot group that was a vertical line, with 2 shots in each hole but at three different points of impact. OK, now we can conclude the load needs to be tuned to get rid of the vertical. Right? Wrong. Shooter #3 sat down behind the gun and produced a group that strung horizontally but had almost no vertical.
Hmmm… what gives?
Shooting Styles Created Vertical or Horizontal Dispersion
What was the problem? Well, each of the three shooters had a different way of holding the gun and adjusting the rear bag. Shooter #1, the gun’s owner, used a wrap-around hold with hand and cheek pressure, and he was squeezing the bag. All that contact was moving the shot up, down, left and right. The wrap-around hold produced erratic results.
Shooter #2 was using no cheek pressure, and very slight thumb pressure behind the tang, but he was experimenting with different amounts of bag “squeeze”. His hold eliminated the side push, but variances in squeeze technique and down pressure caused the vertical string. When he kept things constant, the gun put successive shots through the same hole.
Shooter #3 was using heavy cheek pressure. This settled the gun down vertically, but it also side-loaded the rifle. The result was almost no vertical, but this shooting style produced too much horizontal.
A “Second Opinion” Is Always Useful
Conclusion? Before you spend all day fiddling with a load, you might want to adjust your shooting style and see if that affects the group size and shape on the target. Additionally, it is nearly always useful to have another experienced shooter try your rifle. In our test session, each time we changed “drivers”, the way the shots grouped on the target changed significantly. We went from a big round group, to vertical string, to horizontal string.
Interestingly, all three shooters were able to diagnose problems in their shooting styles, and then refine their gun-handling. As a result, in a second session, we all shot that gun better, and the average group size dropped from 0.5-0.6 inches into the threes — with NO changes to the load.
That’s right, we cut group size in half, and we didn’t alter the load one bit. Switching shooters demonstrated that the load was good and the gun was good. The skill of the trigger-puller(s) proved to be the limiting factor in terms of group size.

You can benefit from these precision mandrels, trust us…
Controlling cartridge neck tension is a critical aspect of accurate reloading. A very small change in the amount of grip on the bullet can actually have a noticeable effect on accuracy (and group size). You can tune neck tension with different size bushings used with FL-sizing or neck-sizing dies. You can also adjust neck “grip” by annealing your brass, or turning your necks for reduced neck-wall thickness.
But perhaps the most precise way to tune neck grip on the bullet is to use Precision Expander Mandrels. Many top shooters size their case necks down pretty far with a full-length sizing die then use a precision neck mandrel as a final step. This expands the neck back to the precisely-desired neck diameter. Because you are working from the “inside out”, variances in neck-wall thickness become less important. This also ensures you have a perfectly-round internal neck geometry for seating your bullet. (Yes, unfortunately some neck bushings are not perfectly round inside.)
For guys who want ultra-precise control over neck tension (and “grip” on the bullet), 21st Century Shooting now offers Precision Expander Mandrels in .0005 (one-half thousandth) increments. These will be available for most popular match calibers including: .224, 6mm, .25, 6.5mm, .270, 7mm, .308, and .338 calibers. These mandrels cost $17.99 each, or you can get a complete set of nine mandrels in .0005 increments (for one caliber) for $144.99. Listed below are the nine 6mm mandrels:
John Perkins, owner of 21st Century tells us: “Finally! We have our expander mandrels up and ready to order on our website here: http://www.xxicsi.com/expander-mandrels.html.” This is a big deal. James Crofts, past National F-TR Champion, says “WooHoo — great news!”
To get best results with these precision mandrels, John recommends using the 21st Century Expander Die Body, part #904. Watch video for set-up tips:
John adds: “We are still in the midst of turning all of these so some calibers will ship when they are completed. Should have them all done by end of next week or so! Thanks for your patience while we got these set up and in process!”

In the benchrest game, both 100/200 yard disciplines and Long Range, it’s important that your rifle track smoothly and repeatably every time. You want the rifle to come straight back without twisting, rocking, or hopping on the bags. When you’re trying to drill your entire 5-Shot or 10-Shot string quickly, it’s also important that the gun returns to the same position after each shot. When the scope crosshairs return to virtually the exact point of aim, you can make successive shots with minimal aim adjustments.
For top “runners” who try to get five shots down-range in under 20 seconds, not having to make significant aiming corrections with your front rest controls can really speed up the process. Shooting quickly permits the competitor to “stay in the condition”, sending all his shots to the target before the wind direction or wind velocity changes.
TEN Shots in 20 Seconds at 1000-Yard Match
To see how rapid shooting works, watch this video of Tom Mosul, one of the USA’s best 1000-yard shooters. In a 10-shot Heavy Gun relay, Tom shoots his 17-lb Light Gun chambered for a 6mmBR Improved cartridge. He pulls the trigger for the first time at 00:20 and he fires his tenth (and last) shot at 00:40. Tom makes TEN SHOTS in 20 seconds, an average of just 2.0 seconds per shot!
TEN Shots in 31 Seconds at 1000-Yard Match
This second video, filmed from the side, shows Tom Mosel shooting a different 17-pounder. Again, note how smoothly the stock slides back and forth. Here Tom completes Ten Shots in 31 seconds, with the first shot at 00:13, and the tenth (last) at 00.44.
Adjustable Stock Rudder Through-the-Lens Video
Gunsmith Alex Wheeler sells stocks with an adjustable metal “rudder” or “keel” on the underside of the rear section of the stock. This rudder is the only part of the stock that contacts the rear bag. This aluminum rudder can adjust slightly left to right as well as adjust up/down for angle. Some guys want the keel nearly flat while others prefer the keel to be slightly lower in the rear.
This video shows how the cross-hairs stay on target once the stock rudder is adjusted properly. Alex adjusted this particular rudder by shimming the height* and moving the back of the rudder to the right.
The rudder’s horizontal adjustability allows benchrest shooters to correct for stock flaws that might adversely affect tracking. Essentially, by adjusting the rudder, you can achieve perfect alignment. Alex Wheeler explains: “If you pull your rifle back in the bags and the cross hair moves, your stock is not straight. The easiest fix is to use an adjustable rudder. They come standard on all my stocks.”
Wheeler explains: “The white box in the center of the 1000-yard target is four inches square. With a properly-adjusted rudder it’s easy to obtain less than one inch of cross-hair movement at 1000 yards.” You can see that, once Alex made the rudder adjustment, there’s hardly any detectable movement. Alex adds, “the more you play with it, the better you get it.”
*Initially Alex says he is going to shim the front. Later in the video Alex says he shimmed the rear. It can be a trial/error process. Credit Boyd Allen for finding these videos.

OK, if all that isn’t enough, we just found four new targets that we really like, plus our fan favorite “bughole” target.
This is a nicely-designed six-bull grid target. Use this for load development or accuracy testing. Set your scope so you can aim at the orange diamonds while your shots impact in the box above. This target has a visible background grid so it is easy to estimate your group size. You’ll find other load development targets in this Shooters’ Forum Thread.
This target was created using Open Office (Draw) by Forum member TwoBoxer for 100-yard load development and practice. He tells us: “The color, size of the center dot, crosshair lines, etc. were varied to work with my scope and magnification at 100 yards. I expect the group POI to move as elements of the load are varied. So concern about obliterating the aim point is minimal, and needs to be controlled by how you zero the rifle in any case.”
With this playing card-themed target, each shooter takes five shots and the one with the highest hand wins. You can also shoot for four-of-a-kind, against the clock, fastest four (without a mistake) wins.

3. Ammo Caddy on Joystick Arm – Charles shoots a Right Bolt/Left Port action, so he pulls his rounds with his left hand. Note that Huckeba’s record rounds rest in a small, wood ammo caddy attached to the end of the joystick shaft. Look carefully, you’ll see the wood ammo block in place of the normal black ball at the end of the joystick. That allows Charles to pull shots with the absolute minimum of hand movement. Ingenious! Huckeba is very fast, with a great economy of motion. I believe that because his ammo was literally at hand, Charles was better able to keep his focus on aiming and the flags.

There’s a simple, inexpensive “miracle device” that can cut your groups in half. If you’re not using this device, you’re giving away accuracy. The “miracle device” to which we refer is a simple wind indicator aka “windflag”. Using windflags may actually improve your accuracy on target much more than weighing charges to the kernel, or spending your life savings on the “latest and greatest” hardware.
1. Align Front Rest and Rear Bags. We see many shooters whose rear bag is angled left or right relative to the bore axis. This can happen when you rush your set-up. But even if you set the gun up carefully, the rear bag can twist due to recoil or the way your arm contacts the bag. After every shot, make sure your rear bag is aligned properly (this is especially important for bag squeezers who may actually pull the bag out of alignment as they squeeze).
3. Weigh Your Charges — Every One. This may sound obvious, but many folks still rely on a powder measure. Yes we know that most short-range BR shooters throw their charges without weighing, but if you’re going to pre-load for a club match there is no reason NOT to weigh your charges. You may be surprised at how inconsistent your powder measure actually is. One of our testers was recently throwing H4198 charges from a Harrell’s measure for his 30BR. Each charge was then weighed twice with a Denver Instrument lab scale. Our tester found that thrown charges varied by up to 0.7 grains! And that’s with a premium measure.
5. Check Your Fasteners. Before a match you need to double-check your scope rings or iron sight mounts to ensure everything is tight. Likewise, you should check the tension on the screws/bolts that hold the action in place. Even on a low-recoiling rimfire rifle, action screws or scope rings can come loose during normal firing.
Back in the old days, Pat McMillan told me: “You can not have two bags filled so hard that you gun bounces on them in the process of firing round at your target, especially if you have a rig with a very flexible stock. The bags must be set up in a manner for them to absorb the initial shock of the firing pin moving forward and igniting the primer. 
Have a good look at the photos below — this may be one of the most noteworthy target strings we’ve ever published. What you can see is the effect of barrel tuner position on point of impact (POI). You can clearly see that the tuner position alters the up/down POI location in a predictable fashion.
