Here is Ernie Bishop’s pride and joy, a specialty pistol nicknamed “Batman” because the black carbon-fiber stock looks like the Batmobile. This is one sophisticated handgun. Complete with scope, the Batman pistol weighs under 7.5 pounds, thanks to the ultra-light stock. The carbon stock is 6 inches wide at the fore-end, yet weighs just one pound. Ernie tells us: “This gun shoots amazing and is easy to shoot especially with my SEB MAX Rest.” After these photos were taken, Ernie added a “field-usable rear-grip stock so [he could] shoot it prone from a bipod as well.”
The Batman pistol is chambered for the 6mm “Long Dasher”, a 6mm 40°-shouldered variant of the 6.5×47 Lapua. Ernie loads Berger 105gr Hybrid bullets pushed by Hodgdon H4350 powder.
Gun Specifications The gun, crafted by Eric Wallance of Nawaka Firearms, features an XP-100 action, Jewell trigger, and 15″-long, Brux 1:8″-twist barrel with aluminum muzzle brake. Interestingly, this gun does not have a traditional recoil lug. Instead, gunsmith Wallace milled out a lug from the bottom of the XP-100 action to save weight. On top of the action, the rig carries a Sightron Inc S-III 6-24X56mm scope in Kelbly rings on a custom +20 MOA rail.
Long Dasher Wildcat
Shown at right is a “Long Dasher” 40° wildcat created by Forum member Sunbuilder. This is very similar to Ernie Bishop’s chambering, though there may be small variations related to reamer design (such as freebore). Sunbuilder’s 6-6.5×47 Improved (aka “Long Dasher”) reamer was made by Dave Kiff of Pacific, Tool & Gauge. This wildcat cartridge adds about 2.0 grains capacity to the 6.5×47 necked down to 6mm. The case certainly is impressive with that 40° shoulder. We’re just waiting for the tactical guys to starting run this improved cartridge with its original 6.5mm bore.
Here are three FIVE-shot groups at 500 yards, shot by Ernie’s Batman pistol. The first 5-shot group is marked with pink dots, the second with green dots, and the third is measured with the calipers:
Every Saturday we present interesting, informative videos for our Daily Bulletin readers. Here we feature five YouTube videos that offer a ton of useful information for serious shooters. We start with a great video about setting up rifle, rest, and bag on the bench. Then Hall-of-Fame benchrest shooter Speedy Gonzalez shows smart methods for cleaning barrels. Next F-Class Ace Keith Glasscock explains how to optimize your rifle after travel. In the fourth video, AutoTrickler inventor Adam MacDonald shows how to optimize the AutoTrickler V4. Next the truly outstanding 21st Century Power Neck-Turning lathe is showcased.
How to Set Up Your Rifle, Rest, and Bag on the Bench
To get the best results in benchrest shooting, you need to set up all the gear on your bench properly. That includes front rest placement, rear bag position, spotting scope set-up, and placement of cartridge holder/caddy, and possibly an elbow/forearm rest. When setting up the hardware, you need to align the front rest and rear bag properly to get optimal tracking. In addition you want to make sure the rear bag doesn’t slide or rotate a bit from shot to shot. And you also want to set your seat height/location so the shooter’s position is optimal and comfortable. This helpful video shows how to set up your rifle and gear for a benchrest match or load development/practice at the range. Credit to Boyd Allen for finding video.
Cleaning Barrels with Speedy — Smart Techniques
There are many effective methods to clean barrels. But some are more efficient that others and can help you do the job more quickly, with less effort. Here respected gunsmith and Hall-of-Fame benchrest shooter Speedy Gonzalez shows his procedures for cleaning competition barrels. He uses Sharpshoot-R Liquid Patch-Out and Wipe-Out Accelerator as primary solvents. Watch carefully — Speedy has some clever techniques for starting a patch in the rifling, and he is also careful about exiting the muzzle when brushing. Speedy also explains the importance of keeping your rods clean. And he prefers nylon brushes because, as the barrel starts to get wear in the throat, “the bronze bristles will actually start eating into that and you’ll see little grooves if you have a good borescope.” (See video 00:38-01:35)
Loading for PRS vs. F-Class — Keith Glasscock
Keith Glasscock is one of America’s top F-Class shooters, having finished second at the National Championships multiple times. He also now shoots PRS/NRL Precision Rifle matches. Keith, who has an engineering background, runs the popular Winning in the Wind YouTube channel. There you’ll find great advice on wind reading, load tuning, precision reloading and many other topics. In this video, Keith offers very smart advice on how to optimize a PRS load compared to a F-Class load. Accuracy counts for both disciplines, but the key objectives can be different.
Adjusting AutoTrickler V4 with its Inventor, Adam MacDonald
Adam MacDonald is the brilliant Canadian engineer who created the AutoTrickler series of automated powder dispensing systems. These work with advanced scales to dispense powder rapidly, but with a precise final trickle accurate to a single kernel. In this video, Adam explains how best to adjust and calibrate the AutoTrickler V4 when using powders that flow at different rates.
21st Century Power Neck-Turning Lathe — Great Tool
Turning case-necks can be tedious and tough on older hands if you’re using hand-held tools. Quite a few years ago 21st Century released a great compact, neck-turning lathe that delivers superb, consistent results. This Editor uses that original lathe with hand crank and I can affirm that it works great. It is easy to use, fast, and the turned necks come out smooth with consistent rim thickness. But you still had to turn a crank. Well, in 2018, 21st Century created an upgraded Power Neck-Turning Lathe with an electric motor and lever to advance the cases to the cutter. The power head glides on stainless steel guide rails. Power is controlled with a red button in the feed handle.
This advanced, powered mini-lathe is absolutely superb. It works brilliantly and makes the task of turning case-necks fast and VERY easy. And there is even a 3-Way trimmer upgrade that will trim cases to length at the same time as the necks are turned.
BONUS — How to Spot Fake Online Sellers of Components
With the shortage of premium reloading components, particularly powder and primers, many handloaders are desperate to find components when even big companies such as Midsouth and MidwayUSA are completely sold out. Enter the scammers. There are criminals, many based overseas, who have created entire websites designed to steal your money. You might find such a site when searching for “Varget powder in stock” or “CCI BR4 primers”. These sites look like regular business webstores, with product photos and modern shopping cart systems. But it’s all a scam.
Key giveaways are: 1) The site does NOT take Visa, Mastercard, or Discover but requires payment with Zelle, Venmo, Bitcoin, or AppleCash only; and 2) The site has hard-to-find powders, such as H4895 and H4198, that nobody else has, and you can put thousands of pounds in the shopping cart.
Bottom line here — if the site allows you to order vast amounts of powder and/or primers, and does not take ANY major Credit Card types, it is almost surely a scam. If you see links to pay with Crypto-Currency (such as Bitcoin) run away!
Rimfire Benchrest can be fun and rewarding. It can also be frustrating because sourcing superior lots of ammo is a never-ending challenge. Still we like rimfire benchrest because you don’t need to load at the range. Plus rimfire barrels last a very long time (our friend Joe Friedrich set an ARA Benchrest record with a 100,000+ round-count barrel). Here’s a great video from the National Rimfire Benchrest Association of Ireland (NRBAI). Production quality is excellent! We highly recommend you watch this video, which does a great job illustrating both the fun and challenge of rimfire benchrest competition.
If you’ve never seen 50m Rimfire Benchrest competition, this video is well worth watching:
“If you need to get your mind away from everything… then look down a scope, concentrate, and be disciplined.”
“Comradery is one of our organization’s key traits… there are no barriers of gender, age or mobility. Just a very diverse, bunch of good people enjoying a sport together.”
“The skill, in brief, is having the ability to hit the equivalent of the top of a pinhead at 50 meters, in all conditions with a .22 round. Not easy, especially when you have to do it 50 times to get a maximum score of 500 [points], 250 per sheet.”
Back in the USA — The National 50 Benchrest League
If this article has motivated you to try rimfire benchrest competition back here in the good ol’ USA, there is a great organization that can help. Launched just a few years ago, the National 50 Benchrest League (N50) has easy-to-understand rules, and offers competition with a wide variety of rifles, even including air rifles. The whole idea was to make competition more affordable and get more shooters on the firing line. There are three classes — Pellet, Sportsman, and PRO. One can be very competitive in the Sportsman Class with a basic factory .22 LR rig or Air Rifle.
N50 competition is unique in allowing air rifle shooters to compete side-by-side with rimfire shooters. This allows folks to compete without the cost of expensive “top-dollar” rimfire ammo. Pellets are relatively inexpensive, and yes air is still free!
About N50 — The National 50 Benchrest League
Commentary by Joe Friedrich, Open Grove Benchrest
The National 50 Benchrest League (N50) offers a unique shooting experience. We shoot air rifles with pellets and slugs alongside .22 LR Rimfire shooters. We currently have sanctioned clubs throughout the USA offering competition and good fellowship.
N50 has three Classes: Pellet, Sportsman, and PRO. The first Pellet Class is strictly for pellet airguns ranging in calibers from .177-.30 using Diabolo-style pellets from various manufacturers.
The second class is the Sportsman Slug/Rimfire. This combined class allows any factory air rifle shooting commercially-made slugs in calibers from .177-.30 to compete against any factory rimfire that utilizes a factory-barreled action with no attachments to barrel. Pellet air rifles may also compete in this class.
The third class is the PRO Class, and no you do not have to have some magic card that says “Professional” to compete. This class allows purpose-built air rifles, and what we call “unlimited” rimfire rifles to compete. Three types of loads are allowed in PRO Class: .177 slug air-driven, .22 slug air-driven, and any .22 LR ammunition.
Another point — in N50, competitors are allowed to move up in class — you aren’t restricted to a “lower” division. For example, Pellet Class shooters can also move up to shoot in Sportsman and Pro. In addition, Factory rimfires are allowed in Pro Class. This way shooters with the less-expensive rifles can shoot more relays and also see how they compete with the unlimited rigs. It’s all about having fun.
We wanted to make N50 as simple as we could combining air rifles with rimfire so folks who have a factory rimfire can participate and have fun. We also did not want a lot of classes, so combining the two gun types would be simpler. To be honest we were worried that the rimfires will outpace the air rifles, but that was not the case at this year’s Nationals.

National 50 Benchrest League Rules and Course of Fire
The official N50 website, National50.net, lists N50 rules, classes, courses of fire, and membership requirements. There are currently 16 affiliated clubs nationwide, with more coming soon.
General Rules — Here are some of the more notable N50 General Rules that apply to N50 matches:
Target Distance: 50 yards
Match Times: 20 minutes per target
Targets: Official targets produced and distributed by N50
Aggregate Score: Cumulative score of 3 targets shot in sequence on same day
Scoring: No competitor shall score their own target
As far as hardware, N50 is pretty open. For all 3 classes, any scope is allowed and any trigger is allowed. For all 3 classes, stocks are unrestricted, stocks may be bedded, and rifle weight is unlimited. However, the Sportsman Class must retain factory barrel and action. N50 competitors in all classes may use 1-piece rests, 2-piece rests, bags, or bipods — whatever they prefer.

We first ran this story a few years back. But it’s still a very interesting subject for benchrest shooters. Shown above, the 30 BR (a 6mmBR necked up to .30 caliber) currently rules the benchrest-for-score game. However, a 30 BR Improved offers some potential advantages, particularly when the winds are strong or tricky. In this article Al Nyhus explains his 30 BRX wildcat. Running Hodgdon H4198, Al says he gets an easy 150 – 200 FPS more than the conventional 30 BR. That can translate to less drift in the wind. It also lets you pursue a higher speed node, which can lead to improved accuracy with some barrels.
Forum member Al Nyhus is a top-level score shooter who has competed successfully with the 30 BR cartridge in VFS (Varmint for Score) matches. Al has been working on an “improved” 30 BR cartridge that delivers extra velocity. Al’s 30 BRX cartridge is inspired by the 6mm BRX cartridge, popular in 600-yard benchrest and across-the-course competition. The 6mm BRX cartridge maintains the same sidewall profile and shoulder angle as the parent 6mmBR case. Likewise, the 30 BRX retains the 30° shoulder used on the popular 30 BR cartridge.
Al reports: “Thought you might like to see what I’ll be working with in my VFS gun this season. It’s a true 30 BRX — a 30 BR with the shoulder moved forward 0.100″ with the standard BR shoulder angle. Stan Ware of SGR Custom Rifles built one last season for Steve Grosvenor and I was really impressed by the performance of Steve’s gun. The 30 BR barrel on my VFS gun needed replacing, so the new 30 BRX got the nod.”
30 BRX Delivers 150-200 FPS More Velocity than 30 BR
Al says his 30 BRX gives a solid 150-200 fps speed gain over the 30 BR at the top, while needing just 2.5-3.0 more grains of Hodgdon H4198 to do so. A 30 BR case holds on average 40.8 grains of water, while the 30 BRX holds 42.3 grains (roughly 4% more). So the 30 BRX delivers a 7% increase in velocity with a mere 4% increase in H20 capacity. That’s pretty good efficiency. [Editor’s Note: Assuming 34 grains of H4198 is a typical 30 BR match load, Al’s increase of 2.5-3.0 grains for the 30 BRX represents roughly a 7.5-8.5% increase in actual powder burned. That explains the higher velocities.]
Why did Nyhus decide to try an “improved” 30 BR?
Al explains: “The 30 BRX was created to operate at a [higher] velocity level than can be achieved with the standard 30 BR case, while at the same time keeping the easy-tuning characteristics of the standard 30 BR case. We also wanted to use the same powders currently used with the 30 BR and maintain similar operating pressures.” Is the 30BRX harder to shoot because of the increased velocity? Al doesn’t think so: “In a 13.5-lb HV gun, the 30 BRX case is a pleasure to shoot with just a flea bite of recoil.”
Will the 30 BRX Become Popular in Score Competition?
The 30 BR is already an exceptionally accurate cartridge that dominates short-range Benchrest for Score competition. Will the 30 BRX make the standard 30 BR obsolete? Nyhus doesn’t think so. However, Al believes the 30 BRX offers a small but important edge in some situations: “On any given day, it’s the shooter that hits the flags best and makes the fewest mistakes that ends up on top. No amount of velocity will save you when you press the trigger at the wrong time. Missing a switch or angle change at 200 yards that results in 3/4″ of bullet displacement on the target can’t be compensated for with another 200 fps. That’s the hard fact of benchrest shooting. But on those days when, as Randy Robinett says, ‘our brains are working’, the BRX may offer enough of an advantage to turn a close-but-no-cigar 10 into an ‘X’ at 200 yards. Or turn a just-over-the-line 9 into a beggar 10.” Given the fierce competition in Score matches, an extra 10 or another X can make the difference between a podium finish and also-ran status.
This impressive 15-round group was shot by Jim See of Elite Accuracy.
Different Shooting Disciplines Demand Different Levels of Precision/Accuracy
In the rapid-fire 3-Gun game, you could probably “clean” most stages with a 2-MOA rifle. By contrast, in the short-range group benchrest game, to compete with the best, you’ll need a rifle that shoots in the “ones” (i.e. 0.1-0.19 MOA) in perfect conditions. In 1000-yard F-Class competition, the top shooters want a rifle that will hold one-third-MOA of vertical at that distance.
What is your standard of accuracy? How good is “good enough”. Jim See, a skilled gunsmith and successful PRS competitor, recently answered that question for his tactical discipline. For the kind of matches Jim shoots, he likes to have a rifle that will hold half-MOA for five (5) shots, 3/4-MOA for 15 shots, and 1 MOA for twenty shots. Remarkably, Jim’s rifle can do that with factory ammo. Above is an impressive 15-shot group shot with .260 Remington Federal Premium Ammo.
“I say it all the time, my loads need to print 5 under 1/2″, 10 under 3/4″, and 20 under 1″. It’s simple, if a hot barrel will keep 20 rounds fired in succession under my standard it will be a good barrel and load for Precision Match Shooting. Federal Premium Gold Metal Match .260 with Sierra bullets made the cut for me today. 15 consecutive shots under 3/4 MOA.” –Jim See
It’s said that you “can never have too much accuracy”, but there are acceptable standards for each discipline, and they’re not the same. A 100/200 yard Benchrest shooter will be sorely disappointed with a rifle/ammo set-up that can only deliver half-MOA. On the other hand, a PRS competitor like Jim See can achieve great success with a lesser degree of precision. This means you can save time and money. You can run your barrels longer between cleanings, and you don’t have to go “full OCD” when loading your ammo. The PRS shooter does not need to weigh-sort primers, or load powder to single-kernel standards. Proof is the performance. Jim See recently took third place at the Spearpoint Shootout, and he has been a podium finisher at other events. Learn more about Jim’s gunsmithing and training operations at EliteAccuracy.com.

Jim’s target seemed a bit familiar. AccurateShooter.com created this Diamond and Dot Target a few years back. On each aiming point, there are high-contrast black horizontal and vertical lines for aligning your cross-hairs. The gray circle lets you see the bullet impacts above, without obliterating the red diamond, which is quite useful for precise aiming (we put fine cross-hairs on the points of the diamond). This target sheet includes data entry tables below each of the three aim points. There are many other free targets out there, but this format is very popular. We’re pleased to see Jim using it.

Credit our buddy Joe Friedrich for this simple yet effective accessory for your benchrest rifle. Joe shoots a .22 LR benchrest rig with a barrel tuner. When he added weights to his tuner, he found his rifle no longer balanced well. He wanted to add some weight in the rear without drilling holes in the stock. He also wanted the weight to be removable, and easily placed on another rifle in his stable. He wanted a weight that could be moved from gun to gun as needed.
At a local sporting goods shop Joe found a 1.5-lb ankle weight that comes in a padded, tubular elastic cover. It’s like a 1.5-lb sausage in a soft, stretchy nylon cover. (Imagine a really fat, heavy bungee cord). Joe simply attached a plastic zip tie at the end to make a loop that fits perfectly over his buttstock. CLICK HERE for full-screen photo.
To “tune” the rifle’s balance, Joe just slides the ankle weight fore and aft on the stock. We have tried this moveable ankle weight on a variety of different BR stocks (including a McMillan Edge) and it worked perfectly. This is a great invention, and would work with sporter rifles and ARs just as well.
NOTE: Obviously, this ring will increase the measured weight of your rifle. So, if you are competing in a registered match with weight restrictions, you have to ensure that your rifle still makes class weight limits with the ankle weight ring in place.
Vertical stringing is a common problem that all precision shooters will face sooner or later. In addition to ammo inconsistencies, many other factors can cause vertical stringing. Accordingly, it’s important that you analyze your gun handling and bench set-up systematically.
EDITOR: Folks, READ THIS ARTICLE! You WILL benefit. There are some VERY important insights here. You’ll learn ways to set up your gun better, and check for various technical issues. That can save you time at the range and save you money spent on expensive bullets and powder.
In this article, Hall of Fame benchrest Shooter Speedy Gonzalez explains how to eliminate mechanical and gun-handling problems that cause vertical spread in your groups. Speedy’s article addresses the many human and the hardware factors that can cause vertical.
Speedy Gonzalez, noted shooter, gunsmith and member of the Benchrest Hall of Fame, offers these pearls of wisdom to help you eliminate vertical in your shot strings. Remember that vertical can result from myriad gear issues and gun-handling mistakes. Try to isolate one item at a time as you work to improve your groups.
BAGS and REST–VERY IMPORTANT
• Front Rest Wobble — You will get vertical if the top section of the front rest is loose. Unfortunately, a lot of rests have movement even when you tighten them as much as you can. This can cause unexplained shots.
• Rifle Angle — If the gun is not level, but rather angles down at muzzle end, the rifle will recoil up at butt-end, causing vertical. You may need to try different rear bags to get the set-up right.
• Front Bag Tension–Vertical can happen if the front sand bag grips the fore-arm too tightly. If, when you pull the rifle back by hand, the fore-arm feels like it is stuck in the bag, then the front bag’s grip is too tight. Your rifle should move in evenly and smoothly in the sand bags, not jerk or chatter when you pull the gun back by hand.
• Sandbag Fill — A front sandbag that is too hard can induce vertical. Personally, I’ve have never had a rifle that will shoot consistently with a rock-hard front sandbag. It always causes vertical or other unexplained shots.
• Bag Ears — If the channel between the Rear Bag’s ears is not in line with the barrel, but is twisted left or right, this can affect recoil and vertical consistency. And take note — if the bag is off-axis quite a bit, you can also get horizontal stringing.
• Reliability — ALL your bench equipment must work flawlessly. If it doesn’t, get it fixed or get rid of it. We need all our attention on wind flags.
GUN HANDLING and BENCH TECHNIQUE
• Be Consistent — You can get vertical if your bench technique is not the same every shot. One common problem is putting your shoulder against the stock for one shot and not the next.
• Free Recoil — Free recoil shooters should be sure their rifle hits their shoulder squarely on recoil, not on the edge of their shoulder or the side of their arm.
• Head Position — Learn to keep your head down and follow-through after each shot. Stay relaxed and hold your position after breaking the shot.
• Eyes — Learn to shoot with both eyes open so you can see more of the conditions.
• Last Shot Laziness — If the 5th shot is a regular problem, you may be guilty of what I call “wishing the last shot in”. This is a very common mistake. We just aim, pull the trigger, and do not worry about the wind flags. Note that in the photo above, the 5th shot was the highest in the group–probably because of fatigue or lack of concentration.
• Last Shot Low — I hear a lot of discussion about low shots in a group and apparently this occurs a lot on the 5th shot. If your 5th shot that goes out most of the time, you can bet you are doing something at the bench.
• Seating — When possible, bring your own stool so that you can sit comfortably, at a consistent height, every time you shoot.
LOAD TUNING
• Find the Sweet Spot — A load that is too light or too heavy can cause vertical problems. When you’ve tuned the load right, you should see a reduction in vertical. Even 0.1 grain may make a difference, as will small changes in seating depth.
• Primers — If you’re getting vertical, and everything else looks fine, try another brand of primers. And remove the carbon from the primer pockets so the primers seat uniformly every time.
• Case Prep — When you chamfer the inside of your case necks make sure they are smooth enough that they don’t peel jacket material off when you seat the bullet. Bullets with J4 Jackets (like Bergers) and Lapua Scenar bullets seem more prone to jacket scratching or tearing than Sierra bullets.
• Shell Holders — Keep shell holders clean, in both your press and priming tool. I have seen so much dirt/crud in shell holders that the cases end up get sized crooked because the rim is not square to the die.
• Water in Cases — I see people walking around with case necks turned up in the loading block. A lot of the time there is condensation dropping from the roof of your loading area. If one drop of water gets in a case you are in trouble. How many times have you had a bad low shot when it has been raining and you have been walking around with your cases turned up in your block?
MECHANICAL and HARDWARE ISSUES
• Barrel Weight — A lot of rifles are muzzle-heavy. Some rifles have too heavy a barrel and this causes vertical, especially when shooting free recoil. Basically the gun wants to tip forward. The remedy is to trim or flute the barrel, or add weight in the rear (if you can stay within weight limits).
• Unbalanced Rifle — If the rifle is not balanced, it does not recoil straight, and it will jump in the bags. If the rifle is built properly this will not happen. Clay Spencer calls this “recoil balancing”, and he uses dual scales (front and rear) to ensure the rifle recoils properly.
• Firing Pin — A number of firing-pin issues can cause vertical. First, a firing pin spring that is either too weak or too strong will induce vertical problems. If you think this is the problem change springs and see what happens. Second, a firing pin that is not seated correctly in the bolt (in the cocked position) will cause poor ignition. Take the bolt out of rifle and look in the firing pin hole. If you cannot see the entire end of firing pin it has come out of the hole. Lastly, a firing pin dragging in bolt or shroud can cause vertical. Listen to the sound when you dry fire. If you don’t hear the same sound each shot, something is wrong.
• Trigger — A trigger sear with excessive spring load can cause problems. To diagnose, with an UNLOADED gun, hold the trigger in firing position and push down on sear with your thumb. If it is hard to push down, this will cause vertical problems.
• Stock Flex — Some stocks are very flexible. This can cause vertical. There are ways to stiffen stocks, but sometimes replacement is the best answer.
SCOPE ISSUES
• Lock Rings — This year alone I have seen nine lock rings on scopes that are not tight. Guess what that does to your group? Make sure yours are tight.
• Big Tubes Need Tension — We’ve observed that some 30mm scope rings are not getting tight enough, and scopes are slipping in the rings under recoil. This will cause point of aim movement.
• Windage Bases — If you’re using a conventional-style single dovetail with rear windage adjustment, make sure both sides of the windage screws are tight. This can induce both windage AND vertical issues since the rear ring is held down by the windage tension.
AWARENESS of CONDITIONS and READING WIND
• Basic Wind-Reading Rule–If you do not know how to read wind flags or are very inexperienced, try to shoot your group with the flags all going in one direction.
• Rate of Fire — The longer you wait between shots when a condition is changing, the more the condition change will affect your shots.
• Look Far and Wide — Learn to look at the whole field of flags, not just the row in front of you. Many times a change quite a ways out will cause shot to go out of your group well before that change shows up in front of your bench.
• Don’t Fear the Wind — When you realize that the wind is your friend you will become a much better benchrest shooter. By this I mean that wind skills can separate you from other shooters who have equally good equipment. To learn how to read the wind, you must practice in challenging winds, not only in good conditions.
• Watch Wind Direction AND Velocity — Pay attention to angle changes on flags. Even though you see the same windspeed indicators, angle changes make a big difference in your groups.
• Watch While You Wait — Between courses of fire, whenever possible, watch conditions on the range. That way you will be aware of any changes in conditions since your last group and you will be mentally prepared for the new condition.
SPECIAL ADVICE for HUNTING RIFLES
• Clean That Barrel — Most hunting rifle barrels do not get cleaned enough. If you keep barrel clean it will shoot better for you. You should clean your barrel well after every 10 to 12 shots. If you’re lazy, just use Wipe-Out.
• First Shot Inconsistency — Most hunting rifles will not put the first shot (after cleaning) with the subsequent shots. So, after cleaning, if you have a rifle that tosses that first shot high or wide, then shoot one fouling shot before going hunting or before you shoot for group.
• Barrel Heat — Thin-contour “sporter” barrels WILL change point of impact as they heat up. When testing loads for your hunting rifle, take your time and don’t let the barrel get hot on you.
To get the best accuracy out of any benchrest rifle, you need to find the optimal position of front rest and rear bag. The important point to remember is that each rig is different. One gun may perform best with the front rest right at the tip of the forearm (Position ‘D’ in photo), while another gun will work best with the rest positioned much further back. This Editor’s own 6mmBR rifle has a laminated stock that is pretty flexy in the front. It shoots best with the front rest’s sandbag located a good 6″ back from the forearm tip (position ‘A’).
Here’s some benchrest advice that can help you reduce vertical and shoot tighter groups… without spending another penny. Many benchrest shooters spend a fortune on equipment and devote countless hours to meticulous handloading, but they never experiment with their rifle’s position/balance on the bags. This article explains why you should test your rifle in various positions. What you learn may surprise you (and improve your scores).
Next time you go to the range, experiment with the position of your rifle on the front rest, and try a couple different positions for the rear bag. You may find that the rifle handles much better after you’ve made a small change in the placement of your gun on the bags. Recoil can be tamed a bit, and tracking can improve significantly, if you optimize the front rest and rear bag positioning.
This competitor has the front rest positioned fairly far forward but not all the way out. Note the stop on the front rest — this limits forward stock travel.
A small change in the position of the forearm on the front rest, or in the placement of the rear bag, can make a big difference in how your gun performs.
Balance Your Gun BEFORE You Spend Hours Tuning Loads
In the pursuit of ultimate accuracy, shooters may spend countless hours on brass prep, bullet selection, and load tuning. Yet the same shooters may pay little attention to how their gun is set-up on their front rest and rear bag. When you have acquired a new rifle, you should do some basic experimentation to find the optimal position for the forearm on the front rest, and the best position for the rear bag. Small changes can make a big difference.
Joel Kendrick, past IBS 600-yard Shooter of the Year, has observed that by adjusting forearm position on the front rest, he can tune out vertical. He has one carbon-fiber-reinforced stock that is extremely rigid. When it was placed with the front rest right under the very tip of the forearm, the gun tended to hop, creating vertical. By sliding the whole gun forward (with more forearm overhang ahead of the front sandbag), he was able to get the whole rig to settle down. That resulted in less vertical dispersion, and the gun tracked much better.
Fore/aft stock position is important even with very wide fore-ends.
Likewise, the placement of the rear bag is very important. Many shooters, by default, will simply place the rear bag the same distance from the front rest with all their guns. In fact, different stocks and different calibers will NOT behave the same. By moving the rear bag forward and aft, you can adjust the rifle’s overall balance and this can improve the tracking significantly. One of our shooters had a Savage 6BR F-Class rifle. By default he had his rear bag set almost all the way at the end of the buttstock. When he slid the rear bag a couple inches forward the gun tracked much better. He immediately noticed that the gun returned to point of aim better (crosshairs would stay on target from shot to shot), AND the gun torqued (twisted) less. The difference was quite noticeable.
A small change in the position of the forearm on the front rest, or in the placement of the rear bag, can make a big difference in how your gun performs. You should experiment with the forearm placement, trying different positions on the front rest. Likewise, you can move the rear bag back and forth a few inches. Once you establish the optimal positions of front rest and rear bag, you should find that your gun tracks better and returns to battery more reliably. You may then discover that the gun shoots smaller groups, with less vertical dispersion. And all these benefits are possible without purchasing any expensive new gear.
Here is Ernie Bishop’s pride and joy, a specialty pistol nicknamed “Batman” because the black carbon-fiber stock looks like the Batmobile. This is one sophisticated handgun. Complete with scope, the Batman pistol weighs under 7.5 pounds, thanks to the ultra-light stock. The carbon stock is 6 inches wide at the fore-end, yet weighs just one pound. Ernie tells us: “This gun shoots amazing and is easy to shoot especially with my SEB MAX Rest.” After these photos were taken, Ernie added a “field-usable rear-grip stock so [he could] shoot it prone from a bipod as well.”
The Batman pistol is chambered for the 6mm “Long Dasher”, a 6mm 40°-shouldered variant of the 6.5×47 Lapua. Ernie loads Berger 105gr Hybrid bullets pushed by Hodgdon H4350 powder.
Gun Specifications The gun, crafted by Eric Wallance of Nawaka Firearms, features an XP-100 action, Jewell trigger, and 15″-long, Brux 1:8″-twist barrel with aluminum muzzle brake. Interestingly, this gun does not have a traditional recoil lug. Instead, gunsmith Wallace milled out a lug from the bottom of the XP-100 action to save weight. On top of the action, the rig carries a Sightron Inc S-III 6-24X56mm scope in Kelbly rings on a custom +20 MOA rail.
Long Dasher Wildcat
Shown at right is a “Long Dasher” 40° wildcat created by Forum member Sunbuilder. This is very similar to Ernie Bishop’s chambering, though there may be small variations related to reamer design (such as freebore). Sunbuilder’s 6-6.5×47 Improved (aka “Long Dasher”) reamer was made by Dave Kiff of Pacific, Tool & Gauge. This wildcat cartridge adds about 2.0 grains capacity to the 6.5×47 necked down to 6mm. The case certainly is impressive with that 40° shoulder. We’re just waiting for the tactical guys to starting run this improved cartridge with its original 6.5mm bore.
Here are three FIVE-shot groups at 500 yards, shot by Ernie’s Batman pistol:
.009″ — The Record That Stood for 40 Years.
In 1973 Mac McMillan shot an amazing 100-yard, .009″ five-shot group in a benchrest match. The .009″ group was measured with a 60x microscope for verification. Mac McMillan shot the group using a handbuilt prototype McMillan rifle with an early McMillan stock.
Mac’s .009″ group was the “Holy Grail” of rifle accuracy. This .009″ record was considered by many to be unbreakable, a record that would “stand for all time”. Well, it took 40 years, but someone finally broke Mac’s record with an even smaller group. In 2013, Mike Stinnett shot a .0077″ five-shot group using a 30 Stewart, a .30 caliber wildcat based on the 6.5 Grendel. Stinnett’s .0077″ group now stands as the smallest 100-yard group ever shot in registered benchrest competition.* Read About .0077″ group HERE.
Stinnett’s success doesn’t diminish the significance of Mac McMillan’s .009″ group in the history of benchrest competition. For four decades Mac’s group stood as the ultimate standard of rifle accuracy*. For those of you who have never seen Mac McMillan’s .009″ group, here it is, along with the NBRSA World Record certificate. The target now hangs in the McMillan Family Museum.
*Somebody else might claim a smaller group, but unless moving backers or electronic targets were used, it cannot be verified. Moving target backers are used at registered benchrest matches to ensure that five (5) shots are actually fired in each group. That eliminates any doubt.

Credit our buddy Joe Friedrich for this simple yet effective accessory for your benchrest rifle. Joe shoots a .22 LR benchrest rig with a barrel tuner. When he added weights to his tuner, he found his rifle no longer balanced well. He wanted to add some weight in the rear without drilling holes in the stock. He also wanted the weight to be removable, and easily placed on another rifle in his stable. He wanted a weight that could be moved from gun to gun as needed.
In this article, Hall of Fame benchrest Shooter Speedy Gonzalez explains how to eliminate mechanical and gun-handling problems that cause vertical spread in your groups. Speedy’s article addresses the many human and the hardware factors that can cause vertical. 
• Front Bag Tension–Vertical can happen if the front sand bag grips the fore-arm too tightly. If, when you pull the rifle back by hand, the fore-arm feels like it is stuck in the bag, then the front bag’s grip is too tight. Your rifle should move in evenly and smoothly in the sand bags, not jerk or chatter when you pull the gun back by hand.
