Most of us assume that if we weigh our powder carefully (down to the tenth of a grain or less) we can achieve a uniform powder fill from case to case in our handloads. Weighing does ensure that the weight of the propellant in each case is the same, but is the column of powder the same by volume each time? “Not necessarily” is the answer. An interesting experiment by our friend Boyd Allen demonstrates that the manner in which you place kernels in the case can make a significant difference in the height of the powder column within the brass case.
Using a Gempro 250 scale, Boyd measured exactly 30.6 grains of Vihtavuori N-133 powder. He then inserted this powder in the same cartridge case multiple times. (The case has a fired primer in place.) But here is the key — Boyd used various filling techniques. He did a slow fill, and a fast fill, and he also experimented with tapping and drop tubes. What Boyd discovered was that you can start with the exact same weight of powder (in fact the very same set of kernels), yet end up with vary different fill heights, depending on how you drop the kernels into the case. Look at the photos. Despite variations in lighting, the photos show the same 30.6 grains of powder, placed in the same cartridge, with four different methods.
Using funnels with long drop tubes packs kernels more tightly, creating a shorter powder column. That allows you to get more propellant (by weight) into the case.
Boyd Explains the Procedure Used for his Experiment.
EDITOR’s NOTE: So there is no misunderstanding, Boyd started with a weighed 30.6 grain charge. This identical charge was used for ALL four fills. After a fill the powder was dumped from the case into a pan which was then used for the next fill technique to be tried. So, the powder weight was constant. Indeed the exact same kernels (of constant weight and number) were used for each fill.
Boyd writes: “I used the same powder for all fills, 30.6 gr. on a GemPro 250 checked more than once. All fills employed the same RCBS green transparent plastic funnel. The fast drop with the funnel only overflowed when it was removed from the case neck, and 15 granules of powder fell on the white paper that the case was sitting on. The fast-funnel-only drop with tapping, was done with the funnel in place and the case and funnel in one hand, while tapping the case body with the index finger hard, many times (about 20 fast double taps). My idea here was to “max out” the potential of this tapping technique.
The slow drop with the funnel and 10″-long .22 cal. Harrell’s Precision drop tube, was done by holding the scale pan over the funnel and tapping the spout of the pan repeatedly on the inside of the funnel about 1/3 down from the top, with the scale pan tilted just enough so that the powder will just flow. Many taps were involved, again, to max out the technique.
Again, to be clear, after each case filling, the powder was poured from the case back into the scale pan carefully. You may notice the similarity between the fast drop with the drop tube, and the funnel only with tapping. Although I did not photograph it, fast tube drop and tapping (combined) improved on tapping alone, but only to about half as far down the neck as the slow with drop tube. Due to the endless possible permutations, I picked four and left it at that.
I believe that I can make the rough judgment that the scale pan funnel and drop tube technique, which involved a longer drop period, and probably less velocity at the top of the tube, left more room in the top of the case neck than the slow drop from the measure with the same drop tube. You have both pictures, so you can make the comparison.” — Boyd
Does Powder Column Height Variance Make a Difference?
Boyd’s experiment proves pretty conclusively that the method of dropping a given weight of powder can affect the height of the powder column in the case and the degree of powder compression (when a bullet is seated). He showed this to be true even when the exact same set of kernels (of constant weight) was used in repetitive loadings. This raises some interesting questions:
1. Will subsequent cartridge transport and handling cause the powder to settle so the variances in powder column height are diminished?
2. If significant inconsistencies in powder column height remain at time of firing, will the difference in fill level hurt accuracy, or result in a higher extreme spread in velocity?
3. Is there any advantage (beyond increased effective case capacity) for a tight (low level) fill vs. a loose (high level) fill?
We don’t know the answer to these follow up questions. This Editor guesses that, if we tested low-fill-height rounds vs. high-fill-height rounds (all with same true fill quantity by weight), we might see meaningful differences in average velocity. I would also guess that if you fired 10 rounds that exhibited quite a difference in powder column heights, you might see a higher ES/SD than if you shot 10 rounds loaded with a very consistent powder column height (either high or low). But further testing is needed to determine if these predictions are true.

For this week’s Sunday GunDay we’ve selected five fan favorites from the Pride and Joy archives. First up is this custom 30 BR brought to you by ANSHUTER2013 and built by Dave Bruno. We were captivated by the clean lines and handsome looks of the Roy Hunter Curly Maple stock. Nestled in that stock is a BAT B action fronted by a 1:17″-twist James Lederer 24″ HV barrel. A Jewell trigger with fixed 42x44mm Nightforce scope round out this beauty.
This state-of-the-art 6 PPC boasts all top-tier components. And owner Wes R. shoots it with a superb rest/bag/pad set-up that inspires envy. This “Bughole 6 PPC” features a Bat DS action, Bix’N Andy trigger, with Bartlein 1:13.75″-twist barrel. The stock is a super-low-profile Scoville with carbon strengthening. The front rest is a SEB NEO, while in the rear is the new Lenzi sandbag. Folks tell us the Lenzi is super stable, which improves tracking from shot to shot. Note the timer attached to the front rest as well as the nice Edgewood leather bench “blanket” and arm-rest pad.
Forum Member Killick attached PickleForks to his handsome blue Eliseo R1 TubeGun now chambered in .284 Winchester, a top choice for the F-Open discipline. Killick explains: “Behold! An Eliseo R1 F-Classer. This started out as an R1 Long Range sling rifle (6XC) with a Borden TubeGun action. It is now rebarreled in .284 Win with Gary’s PickleFork fore-end adaptor. Props to Gary Eliseo at Competition Machine LLC.”
Sometimes clean and simple is the way to go — particularly with a hunting rifle. WEATHERBYFAN’s 6.5 Creedmoor is built around a Stiller Predator single-shot action in a texturd, green Wildcat Var-Tac stock. The 1:8″-twist Bartlein barrel is finished at 28″. That’s pretty long for a hunting rig, but it delivers added velocity. Finishing off this nice rigle is a Zeiss 6-24x50mm optic. Sometimes less is more and this is a perfect example of that.
Our final offering is from Forum member 300_WHISPER. Completed just months ago by gunsmith CALEB85, this .308 Win rifle features a Bighorn TL3 action with a Bartlein M40 26″ 1:10″-twist barrel, and Manners TA Elite stock. Other components include Trigger Tech Special, Area 419 self-timing muzzle brake, and a Weaver Tactical 3-15x50mm FFP mil/mil optic. When test-fired by Caleb with ammo using Berger 175gr OTM Tactical bullets, this nice .308 Win delivered a 1.6″ 5-shot group at 400 yards. The owner says “It’s my dream rifle. I couldn’t be happier”.

Fire-Form with Foulers
Here’s a tip for guys who shoot the 6 PPC, 6 Dasher, 6 BRA, .284 Shehane, or other wildcat cartridges that require fire-forming. Use your fouler shots to fire-form new cases. That way your fouler shots do “double-duty” and you get your brass fire-formed without putting extra rounds through your expensive barrel.
This procedure is recommended by Joel Kendrick, the 2004 IBS 600-yard Shooter of the Year. After he cleans his barrel, Joel knows it takes two or three shots to foul in the bore before accuracy returns. (YMMV — some barrels may need five or six foulers.) When shooting his PPC, Joel uses those fouler shots to fire-form his new brass. Joel explains: “I like to have relatively new brass always ready. By fire-forming a couple cases after each barrel-cleaning during a match, by the end of the weekend I’ve got a dozen or more freshly fire-formed cases to put into the rotation. If you do this with your fouler shots you get your fire-forming accomplished without using up any extra barrel life.”
This not only saves barrel wear, but it saves you trips to the range for the purpose of fire-forming. We thank Joel for this smart suggestion. For those who do not have a dedicated barrel for fire-forming, this should help keep your round-count down. Note: With this fouler fire-forming routine, you should ALWAYS do the fire-forming with the SAME POWDER you load for your match ammo. Joel currently works as the Supplier Quality Process Engineer for MMI-TruTec, a company that offers barrel surface coatings that can further extend your barrel life.

IMR 8208 XBR powder is a great propellent that has shown superb consistency, delivering great accuracy and low ES/SD in our testing. We have used this powder with success in .308 Win and other cartridges. The burn rate is slightly slower than Vihtavuori N133 and a bit faster than Hodgdon H4895. IMR 8208 XBR is suitable for many cartridge types including .204 Ruger, 22 BR, .223 Rem, 6 PPC, 6BR (lighter bullets), and .308 Winchester. It works great for varmint hunting loads as well as benchrest competition.
If Powder Valley sells out, Natchez Shooting & Outdoors also has some IMR 8208 XBR one-pounders in stock. Current price is $51.69 (one-pound). Also Brownell’s has 8208 XBR one-pounders in stock for $55.99. NOTE: Neither Natchez nor Brownells have the 8-lb jugs of IMR 8208 XBR.
Stellar Accuracy and Exceptional Temperature Insensitivity
Field testing has shown that IMR XBR 8208 is extremely stable across a very wide temperature range. At SHOT Show 2010, we interviewed Chris Hodgdon, who gave us the “inside story” on this IMR powder. Chris shared lab test results showing how load pressure varied with ambient temperature. The data was stunning. Basically 8208 XBR showed almost constant pressures from below freezing to well over 100° F. This editor has personally never seen a powder test that revealed “flat-line” results like 8208 XBR, with recorded pressures remaining virtually unchanged over a huge temperature range. And IMR 8208 XBR has been used with great success in benchrest competition by Lou Murdica and others. When you combine its temp stability with such proven accuracy, IMR 8208 XBR is indeed a very exceptional powder.

One of the most important short-range benchrest matches on the planet kicks off tomorrow. The Super Shoot, official Super Shoot 50 this year, will draw top group-shooting benchrest aces from around the world to the USA this week. The match will be held at the excellent Benchrest Rifle Club in Missouri. The match officially starts on May 20th, but the BRC was open for practice this weekend (see schedule below).
This event has been called the “premier benchrest match of the year”. The course of fire has Light Varmint and Heavy varmint group size competition at 100 yards and 200 yards. Most of the rifles will be chambered for the 6mm PPC cartridge shooting bullets under 70 grains. Every year the Super Shoot attracts top benchrest competitors from many countries around the world. Along the firing line you’ll find Hall-of-Famers and past National Champions.
This year marks a milestone for the Super Shoot — as Super Shoot 50 will be held May 20-23, 2024. Historically, the Super Shoot has been the most prestigious benchrest match in the world. This year the Super Shoot will be held at one of the premier facilities in the United States, the Benchrest Rifle Club in St Louis, Missouri. Sponsors this year include: Bartlein Barrels, BAT Machine, Bruno Shooters Supply, Krieger Barrels, MidwayUSA, MTM, PMA Tool, Redding, and Shilen Rifles.

Last month, Orangeburg, South Carolina became the epicenter of rifle competition on November 4-5, 2023 as the Mid-Carolina Gun Club hosted the widely-acclaimed Tack Driver IV. The Tack Driver has rapidly grown in popularity and stature, becoming a yearly must-attend event. The match’s rise in popularity can be attributed to several factors, including its organizer, the spirited Jim Cline, renowned for his quick wit, larger-than-life persona, and affinity for pranks. The Tack Driver’s popularity and status is further boosted by its unique format: shooting a mix of group and score targets at 300 meters. It has a generous 22-pound rifle weight limit and extends an invitation to all precision shooting disciplines. Competitors get the opportunity to compete with some of the world’s best shooters, have a great time, enjoy fantastic food, and see if they have what it takes to earn the title of “Tack Driver”.
What is the Tack Driver Match
For the uninitiated, the Tack Driver is a 300-meter “take-all-comers” match designed to answer the age-old question of which combination of caliber and shooting discipline is the most accurate. The rules are simple: all rifles will be fired from a bench, 22-pound weight limit, caliber must be .338 or smaller, and no one-piece rest is allowed. Each competitor will alternate shooting 5 group targets and 5 score targets over the course of two days. There are a few more rules, but those are the basics.
The Tack Driver’s course of fire alternates between score targets and group targets. So competitors must demonstrate both precision and accuracy. The group targets test precision, measuring only the group size for 5 record shots. Meanwhile, the score targets demand accuracy with a goal of hitting 5 separate 1″-diameter bullseyes, each with a single shot (ideally obliterating the dot in the center). Each target has a designated area for unlimited sighters during the 7-minute match. At the end of the match, the shooter with the best combination of the highest score and smallest group aggregate wins.
Beginning of Tack Driver IV — Cool Temps and Light Winds
Bright blue skies, light winds, and cool temperatures greeted the 99 competitors in attendance to compete for the title of Tack Driver Champion. The match, since its inception, has attracted a deep list of “Who’s Who” in the world of precision shooting. In attendance are World Record Holders, National Champions, Hall of Famers, Shooters of the Year, and World Team members. Literally the “best of the best” from UBR, Score, Group, 600-yard, 1000-yard, and Ground Hog competitions, were competing in this unique contest of “precision and accuracy.”

George loaded his 6mmBR rifle with H4895 powder and Berger 90gr HPBT bullets. At 300 meters this 0.337″ group works out to 0.098 MOA (one MOA is 3.435″ at 300 meters).
Saturday Night Cookout with Smoked Prime Rib
With the range closed and targets hung, shooters and family members began gathering at the pavilion (on top of the hill) for the 6:30 feed. With a main course of Smoked Prime Rib, it was a packed house. Previous nights the shooters were treated to a low country boil and grilled chicken. The food throughout the event, lunch and supper is simply amazing. It’s a 5-Star dining experience served with paper plates and napkins. Here is a video of folks enjoying the festivities.

Prelude — Tack Driver Lite (November 2, 2023)
This year started with a new event, “The Tack Driver Lite,” held on Thursday morning. two days prior to the regular Tack Driver. The match has two goals: first, to give early-arriving competitors something to do, and second to get the match director, Jim Cline, out from behind his computer and see how he stacks up against the competition. The Tack Driver Lite format is similar to the regular Tack Driver but with a couple of twists. The match consists of 4 targets (2 Score & 2 Group) instead of the usual 10 (5 Score & 5 Group). Each competitor was allowed to put out one flag. Prior to drawing a bench the shooter had to state at what range he would put his flag. Competitors have 7 minutes to shoot one Score and one Group target. The next twist is the targets were hung sideways, one on top of the other, instead of the normal straight up and down. It really shouldn’t make a difference, but visually and mentally it did. With the temperature in the low 30s and light and variable winds, twenty shooters took to the line.
Results of Tack Driver Lite
When the dust had settled Roy “The Renaissance Man” Hunter (photo below) found himself the winner of the score portion of the match, shooting clean with a perfect score of 100. Top dog was Billy Stevens who won both the Overall Grand Aggregate (combined score and group) and the Group Aggregate with a 0.689.

Hardware Choices: Actions, Stocks, Barrels, Optics and More Tech Talk by Jeff Stover
This article was prepared by past IBS President Jeff Stover based on results from the 2019 IBS 100/200 Group Nationals held August 12-17, 2019 at the Holton Gun & Bow Club in western Michigan.
Let’s examine the Top Ten rifles from the IBS Group Nationals in the 10.5-lb Light Varmint Class. We’ll focus on the most popular rifle components — the choices for Actions, Stocks, Barrels, and Scopes.
Hall of Famer Jeff Gaidos taking aim at the 2018 IBS Group Nationals. He has a low-profile carbon-fiber stock with a Leupold fixed-power scope.
For some years now, BAT has been the predominant action. This year BAT actions held nearly 100% of the Top Ten places in all the Bag Gun equipment lists. Bruce Thom’s Idaho-crafted actions, except for a couple stray actions in Heavy Bench, swept the top rankings.
Next, look at barrels. Bartlein or Krieger seem to rule with upstate New York’s venerable Hart barrels as competitive. Shooters tend to go with winners, so Wayne Campbell and Jeff Peinhardt dominate as gunsmiths for the top benchrest shooters.
In stocks there seems to be variety, but there is some commonality. The Scoville and Scarbrough stocks, both Michigan-made, are laminated wood (balsa and other wood) with carbon fiber and wrapped in carbon fiber. The Scoville stock on my 10.5-lb rifle weighs 18 ounces but is full size with a nice long fore-end. Bob Scarbrough makes a very similar product. Both are winners — it’s a choice of Ferrari or Lamborghini. The Roy Hunter and Terry Leonard stocks among these top rifles take a different route to winner’s circle. Both are wood (cedar or other), but super high-tech as they are laminated with carbon fiber. They are beautiful to boot. High-magnification Leupold, March, and Nightforce scopes rule the roost among benchrest optics.
Bullets and Powder
Bullets are important. Really important. A hot bullet gives you “Teen Aggs” and lots of trophies. An average bullet does not. Most of these are 68 grain 6mm boattails. The Peinhardt (StaMoly Precision) bullet is well represented on this list, but some top shooters make their own as you can see. Bullet jackets are likely StaMoly or J4. For powder, nearly everyone shoots Vihtavouri N133 except a few guys running LT30/32 or surplus 8208.

Here is one of Bill Reid’s 6mmBR (6BR) rigs. Like his Sako 6 PPC, this is exceptionally accurate.
AccurateShooter Forum member Bill White (aka “CT10Ring”) is a New Yorker who relocated to Idaho in his senior years. From his Idaho home, Bill enjoys long-range target shooting. But his favorite gun pastime is varmint hunting in nearby states — the Dakotas, Montana, and Wyoming. Every year he loads up his truck and hits the road, often doing a grand circle route, visiting prairie dog havens in multiple states.
Bill has a large rifle collection, most of which see duty in the varmint fields of Montana, North Dakota, South Dakota, and Wyoming. Here are his key “take-aways” for his eight favorite varmint chamberings: .204 Ruger, .223 Rem, .22-250, .22 BR, .22-243, 6 PPC, 6mmBR, and 6-6.5×47 Lapua (aka 6×47).
Eight Great Varmint Cartridge Types — .204, .224, .243 Calibers
.204 Ruger — This delivers great velocity with the little .20-caliber bullets, with mild recoil. The .204 Ruger easily reaches out to 400 yards, but heavier winds do move the tiny bullet around. Tremendous splat factor under 250 yards. I use Sierra 39gr bullets with IMR 8208 XBR in a Sako 75. Even now, .204 Ruger ammo is relatively easy to find.
.223 Remington — Probably the most popular centerfire rifle round in the USA, the .223 Rem offers inexpensive brass, and is a great choice for AR-15 owners. If you run short on ammo, you can find it nearly everywhere. I often bring one AR-15 and one .223 Rem bolt gun on varmint safaris. My Rem 700 5R 1:9″-twist barrel likes 53gr V-Max bullets.
.22 BR — My .22 BR is my first choice for most prairie dog missions. Accuracy is superb with necked-down 6mmBR Lapua brass — quarter-MOA and blazing fast. With the right twist rate, this chambering can shoot anything from 40gr FB bullets to 80gr VLDs. Load development is easy. Below is my .22 BR ammo for another varmint trip. I use 55gr Sierra BlitzKings with Varget in my 1:12″-twist Shilen-barreled rifle. 60gr Bergers are very accurate with a fairly flat trajectory for useful distances.
.22-250 Rem — A classic varmint cartridge, the .22-250 with 50gr V-Maxs delivers spectacular hits. If three P-Dogs happen to be lined up, I’ve witnessed one .22-250 shot take ‘em all out with a triple hit. I currently have five .22-250-chambered rifles: 3 Sako 75s, one Rem 700, and a single shot Nesika that shoots tiny groups. I favor the very deadly Berger 52gr Varmint HP. Making a custom .22-250? With a 1:8″-twist barrel you can use the full weight range of .22-cal bullets, while spinning the lighter bullets fast for “red mist” effect. Remember this cartridge can be a barrel burner. Don’t shoot too many rounds too quickly.
.22-243 Win — This wildcat is even more potent than the .22-250, delivering devastating results on P-Dogs. Run a .243 Win case slowly through a full-length .22-243 die, with plenty of lube to form the brass. I start with Lapua .243 Win brass. There can be some issues necking-down the brass. Watch for donuts forming at the neck-shoulder junction. I bought my .22-243 rifle not sure how it would perform. But now I love shooting it. My .22-243 delivers half-MOA groups with 41.0 grains RL-22 and Hornady 75gr Amax bullets. With those 75-grainers, it’s great in the wind and good to 600 yards easily.
6 PPC — You may consider the 6 PPC a benchrest competition cartridge only, requiring fire-forming. However I have an original Sako 75 single-shot 6 PPC rifle that I load with Sako-headstamp 6 PPC brass (see below) so no fire-forming is required. This Sako 75 came with a test target that measured 0.113″! With my 6 PPC Sako, I found that 58gr V-Maxs, pushed by Vihtavuori N133, are potent out to 300 yards. [Editor’s NOTE: As the Sako brass is no longer available, new 6 PPC shooters will need to fire-form their brass, or try to find Norma 6 PPC brass.]
6mmBR — The 6mmBR Norma (6BR) offers a nearly unbeatable combination of accuracy, efficiency, and tunability. With the 6BR and a fast twist barrel, you can shoot everything from 40gr flat-base bullets to the latest 105-110gr match bullets. I load Lapua brass, Vihtavuori N135, and Hornady 58, 65, and 75gr bullets for my Krieger 1:14″-twist HV barrel. While this cartridge is capable of long-range accuracy, I usually limit my 6BR shots to 350-400 yards.
6-6.5×47 Lapua — I have a nice 6-6.5×47 Lapua varmint rifle, with Surgeon action and Manners stock. I Cerakoted the barreled action and then bedded the action. Shown below is 6-6.5×47 ammo I loaded for testing. Note how I separated different bullets and powder loads into multiple, labeled bags. Hodgdon H4350 is a great choice for this cartridge — 39 grains H4350 with 105gr Amax was the winner here, but 88gr Bergers also shot well. This cartridge has tremendous “critter dismantling” abilities out to 600-700 yards.
Six Tips for Novice Long Range Varmint Hunters
1. Take twice as much ammo you think you may need. The fields could be particularly rich, or, because of wind or other variables, you may have far more misses than expected.
2. When possible, set up with the wind at your back (or, alternatively, directly ahead). This will minimize the effect of cross-winds. Set up a stake with a ribbon to show wind direction.
3. Bring at least two rifles. Ideally one would be a low-recoil rifle with cheaper components for the closer shots. Then bring a rifle with higher-BC bullets for longer shots where wind is a bigger factor.
4. Check the weather before you head out. Prairie dogs like sunshine and calm conditions. If a cloudy, very blustery day is predicted, considering staying in town and cleaning the rifles.
5. Bring plenty of water on a trip. An adult male should be drinking at least 64 ounces of water (or other liquid) every day — more if it’s very hot or you are sweating a lot.
6. Preferably always hunt with a companion. If you do go out solo, have a Garmin inReach SatComm/GPS for emergencies if there is no cell coverage in your location.
Bonus for Black Rifle Shooters — The Economical 20 Practical
If you want to use an AR-platform rifle in the varmint fields, consider getting a 20-caliber barrel chambered for the efficient, low-recoil 20 Practical cartridge. The 20 Practical is simply a .223 Remington necked down to 20 caliber. The parent .223 Rem cartridge of course works great in an AR, but the 20 Practical offers some notable advantages for high-volume varmint shooters. The 20 Practical delivers very high velocity with very low recoil while still providing outstanding accuracy. The 20 Practical is great option for folks who favor “fast and light” — smaller, lower-mass bullets traveling at very high velocities. This little cartridge can launch 40-grainers at over 3900 fps, and 32-grainers even faster. This makes the 20 Practical a great choice for an AR-based varmint rifle.
20 Practical Ultimate Varminter
A decade ago, as a “proof-of-concept”, AccurateShooter.com created a 20 Practical AR15 Ultimate Varminter with a custom 20-caliber upper from Robert Whitley of AR-X Enterprises, LLC. That project rifle was ultra-accurate — every 5-shot group out of the gun was less than the size of a dime. That gun was auctioned off, but Robert Whitley continues to produce custom 20 Practical AR15 uppers. (The 20 Practical cartridge is simply the .223 Rem necked down to 20 caliber — you can use standard .223 brass and load with standard.223 Rem dies. Just swap in a smaller expander and use smaller neck bushings.)

The .20 Practical is also a good choice for a bolt-action rifle. Here is what our Forum members have to say…
20 Practical Shooters Explain Why They Love this Little Cartridge
A thread in our Shooters’ Forum asks: “What is your favorite and most versatile round that you have made from a .223 Rem parent case?” Many cartridges were named, but the wildcat cartridge cited most often was the 20 Practical. Here are some comments by Forum members, who explain the appeal of this great little 20-caliber cartridge:
“The 20 Practical is just a hoot to shoot. Outstanding precision, minimal recoil, easy case forming and inexpensive to shoot. What’s not to like? It’s a great way to introduce kids to centerfire, too.” — JLT
“My favorite was and is the 20 Practical. No fire-forming, no neck-turning, and with the increased BC of the 20 Cal bullets, it’s hard to wipe the smile off your face in a prairie dog town[.]” — Region Rat
“Favorite .223 Rem Wildcat? The 20 Practical hands down for me. I have two of them built on Savage actions right now. One has a 20″ BHW barrel and the other has a 26″ Criterion. It is my go-to caliber for shooting up a Prairie Dog town and the ones I have are insanely accurate. Here are some typical 100- and 200-yard groups with my 20 Practicals.” — IA_Shooter

We hope these “Pride and Joy” rifles may provide inspiration for our readers, whetting their appetite for their next competition, varminting, or hunting rifle project.
Eliseo Tubegun in 7mm SAUM with Pierce Action, Bartlein Barrel
Here is a striking camo-finished Elesio (Competition Machine) Tubegun chambered for 7mm SAUM. Note the block fitted to the tubular fore-end so the rifle rides smooth and steady on the Rodzilla T-Rex joystick front rest. The proud owner, Forum member Aeon, tells us: “This is a Gary Eliseo RTM chassis with pickle forks. It has a custom Ceracoat paint job to match my sling gun.” Key components are: Pierce Engineering long action tube receiver, Bartlein 1:8.5″-twist barrel, Jewell trigger set at 2 oz., and Vortex Golden Eagle scope in Vortex rings. Aeon adds: “The chamber was cut by Mark Chesesbro of Chesebro Rifles. Mark throated it very long so the the 180gr and 184gr Bergers would sit where they belong.”
Tuning the 7mm SAUM and Recoil Reduction
Owner Aeon tells us: “The 7 SAUM was as easy a gun as I have ever shot to find a good load for — H1000 gave great consistency and tuning was not hard. However, the challenge in shooting this rifle was recoil management. The 7 SAUM has a punch to it and I found myself having trouble finishing three relays without form problems in the last relay. I considered getting a RAD Pad but that would have required expensive machine work. I stumbled on a recoil pad that is uniquely effective, the Falcon Strike. Sent the pad to Gary Eliseo and he sent it back with the butt plate machined to fit. Complete game changer! The rifle is a dream to shoot now with a big reduction in felt recoil.”
This gray and blue beauty belongs to Forum member Farmer Dave. He posted: “Got this 6.5×47 Lapua back from my smith about six months ago. It’s the most accurate rifle I have ever owned.” This rifle features: AG Composites CF stock, Stiller TAC 30 action, Bartlein 5R barrel, TriggerTech Diamond trigger. On top is a Trijicon Accupower riflescope.
Henry .45-70 with Modern Buttstock and M-LOK Handguard
Here is member Quest45’s handsome lever-action Henry .45-70 Gov and Glock 40 10mm. About his two guns he posted: “All I need is a can of bear spray”. The rifle is fitted with a red dot sight, ammo caddies, Ranger Point M-LOK handguard, and a modernized modular buttstock. These upgrades make it a thoroughly-modern Henry lever gun for the 21st Century.
A .243 Winchester Hunting Rig that Nailed Scottish Roe Buck
Forum member John V. from Scotland showcased a successful hunt with his .243 Winchester rifle. This sports a suppressed, 26″ MTU 1:7.5″-twist barrel. He loaded Sierra 100gr Pro-Hunter bullets, and took this nice Roe Buck at 240 yards through a gap in the foliage.
Ultra-Low Profile 6 PPC for Short-Range Benchrest
This handsome rifle, which belongs to Forum member J.J.Coe, represents the state-of-the-art for 100/200-yard benchrest rifles. It is chambered (no surprise) for the 6 PPC cartridge, which dominates the short-range game. In features a super-low profile carbon composite stock. Note how the vertical centerline of the stock is very close to the barrel. This keeps the center of gravity low and helps the rifle recoil smoothly with less hop in the bags. Note also the tuner on the barrel.
Do-it-Yourself Paint Job, Done in the Bathroom at Home
Many eye-catching rifles start with a great paint job. Forum member JHN did this job himself. He posted: “Went to local paint shops, some cost a two-month work income, some said guns were a ‘no-no’. So I did it myself — my first Candy Apple red. Base collar is gold metallic, followed by the red. I didn’t have a good paintwork place so I had to improvise. Our bathroom has nice concealing in the summer — a perfect paint booth. So I only have to apologize about some red flakes in our bathroom.”
Mauser M96 with Quilted Maple Stock — for the Wife
We like this handsome quilted Maple-stocked Mauser belonging to Forum member Steel Mover. He posted: “Some like synthetic and some like wood — I have both. Here is the wife’s quilted Maple 96 Mauser 6.5×55. I was working in the shop, wife walked through and said ‘You are building that for me aren’t you?’ Well ‘Yes, dear’ I said of course … so I Lost my rifle.”
Patriotic .284 Shehane F-Open Rig
Forum member 1shot is proud of this new F-Classer: “Just got my first F-Open rifle finished chambered in .284 Shehane. It features a Kelbly stock w/RAD system, Shilen 1:8″-twist ratchet-rifled barrel with EC Tuner, and X-treme 2-stage trigger — all mated up to a Kelbly Panda action. I think this dog will hunt!”

Hardware Choices: Actions, Stocks, Barrels, Optics and More Tech Talk by Jeff Stover
This article was prepared by past IBS President Jeff Stover based on results from the 2019 IBS 100/200 Group Nationals held August 12-17, 2019 at the Holton Gun & Bow Club in western Michigan.
Let’s examine the Top Ten rifles from the 2019 IBS Group Nationals in the 10.5-lb Light Varmint Class. We’ll focus on the most popular rifle components — the choices for Actions, Stocks, Barrels, and Scopes.
Hall of Famer Jeff Gaidos taking aim at the 2018 IBS Group Nationals. He has a low-profile carbon-fiber stock with a Leupold fixed-power scope.
For some years now, BAT has been the predominant action. This year BAT actions held nearly 100% of the Top Ten places in all the Bag Gun equipment lists. Bruce Thom’s Idaho-crafted actions, except for a couple stray actions in Heavy Bench, swept the top rankings.
Next, look at barrels. Bartlein or Krieger seem to rule with upstate New York’s venerable Hart barrels as competitive. Shooters tend to go with winners, so Wayne Campbell and Jeff Peinhardt dominate as gunsmiths for the top benchrest shooters.
In stocks there seems to be variety, but there is some commonality. The Scoville and Scarbrough stocks, both Michigan-made, are laminated wood (balsa and other wood) with carbon fiber and wrapped in carbon fiber. The Scoville stock on my 10.5-lb rifle weighs 18 ounces but is full size with a nice long fore-end. Bob Scarbrough makes a very similar product. Both are winners — it’s a choice of Ferrari or Lamborghini. The Roy Hunter and Terry Leonard stocks among these top rifles take a different route to winner’s circle. Both are wood (cedar or other), but super high-tech as they are laminated with carbon fiber. They are beautiful to boot. High-magnification Leupold, March, and Nightforce scopes rule the roost among benchrest optics.
Bullets and Powder
Bullets are important. Really important. A hot bullet gives you “Teen Aggs” and lots of trophies. An average bullet does not. Most of these are 68 grain 6mm boattails. The Peinhardt (StaMoly Precision) bullet is well represented on this list, but some top shooters make their own as you can see. Bullet jackets are likely StaMoly or J4. For powder, nearly everyone shoots Vihtavouri N133 except a few guys running LT30/32 or surplus 8208.

Bullet-maker Bart Sauter is the king of 300 meters, winning his second straight Tack Driver III multi-discipline match in South Carolina. For the second year in a row, Bart won the Tack Driver Grand Agg, after finishing sixth in Group shooting and first in Score shooting. Finishing second overall was short-range Benchrest ace Wayne Campbell. Wayne finished first in the Group-shooting phase and took eighth place in score shooting. Third overall was Jeff Peinhardt who, interestingly, was fifth in Group AND fifth in Score — that’s consistency. According to reports, 6mm PPCs dominated this year’s Tack Driver III match held November 5-6, 2022. We believe 6 or 7 out of the top 10 finishers shot a 6PPC. For decades the 6PPC has been the leading chambering for 100/200-yard benchrest-for-group competition.
The Tack Driver Showdown is a one-of-a-kind “all comers” rifle match. This unique multi-discipline match, with both SCORE and GROUP targets, reveals what rifle types are truly the MOST accurate, at least out to 300 meters. The Tack Driver Showdown III match took place last weekend, November 5-6, 2022 at the Mid-Carolina Gun Club in Orangeburg, South Carolina. The organizers invited virtually any type of rifle (except railguns) to compete at 300 meters for group and score honors. No organization membership is required. There were 89 competitors this year.
Unlike any other rifle match in the world, on the Tack Driver firing line you might see 6 PPC LV/HV rifles, 30 BR score rigs, and 17-lb 600-yard and 1000-yard benchrest guns together all lined up together. There may also be a few F-Class rifles, a PRS rifles, and maybe even an AR15 or two. But in 2022, nearly all the competitors had benchrest-style rifles, the majority designed for the 100/200 yard score and group games. That’s not surprising, as low-profile, smooth-recoiling BR rifles rule the roost at 100, 200, and 600 yards. Here are the list of rifles that competed this year according to cartridge type:
Tack Driver III targets were placed at 300 meters (328 yards). That’s not even “mid-range” by benchrest standards, but it is far enough that higher-BC bullets should have an advantage in windy or rapidly changing conditions. This year, however, the 6PPCs shooting lighter-weight 6mm bullets dominated.
Commentary by Tack Driver III Winner Bart Sauter
Winning Equipment — I shot a 6PPC with a .273 no-turn neck, Bartlein 1:13.5″-twist barrel, BAT DS action, Jewell trigger, Harris tuner, and Scarborough stock. On top was a great big ole 10-60X Valdada “Precision” scope with 40mm tube. I also used Vihtavuori N133 powder and my 68gr boat-tail bullets.
Shooter vs. the Gun — The long and the short of it is… you’re only as good as your equipment and the equipment can only perform up to the ability of the shooter. It’s a system. I’ve won it last year with a 6BRA and now with a 6PPC. I’m telling you, caliber-wise, there are a lot of different cartridges and combinations that can win. Jeff Godfrey (of the Piedmont Mafia) brought his 6BRX (I believe), and it shot like a laser. Jeff was in second place at the end of Day 1. If not for a couple of “Orangeburg Gotchas” Jeff would have been right there for the win.
Rifle and Cartridge Choice — Why did I shoot the 6PPC? It’s simple — the goal for this year was to try to make the benchrest World Team. So my resources were directed towards barrels for the 6PPC. I didn’t buy a single long range barrel this year. I used the last of my competitive long range gear for the 600- and 1000-yard Nationals. If I had both the 6BRA and 6PPC working, for this match I’d pick the 6BRA EVERY TIME and TWICE ON SUNDAY.”
Video of Bart Explaining Rest/Bag Set-Up and Showing Shooting Technique
Editor’s Note: 2022 has been a good year for Bart Sauter. He also won the 2022 NBRSA 3-Gun Short Range National Championship shooting his no-turn-neck 6PPC.
Comments by Forum Members:
“Congratulations Bart for your second Tack Driver win! Bart is no doubt a great shooter. He has [the ability] to prepare for a match to the Nth degree, then adapt and overcome changes that arise during a match. Not many have his skill, knowledge, and dedication! Congratulations to all that were there. You are all winners… I hear it was a great time had by all competitors!” — Samuel Hall (Past IBS Champion)
“While the Tack Driver concept is designed to attract shooters from Short Range Group, Short Range Score, F Class, PRS, and all of the other disciplines that require the ultimate in rifle accuracy, it is still a Benchrest match, run under Benchrest rules. Downrange ballistics such as a bullet’s ability to buck conditions take a back seat to a combination’s overall Agging capability. That includes the bullets, the barrel, the tune, the bench equipment[.]” — Jackie Schmidt
“What [the Tack Driver match] shows is the domination of the 6mm bore and small cases. It is a great event to showcase precision bench shooting [with] different disciplines coming together. Good job to Mr. Cline and all those involved including the shooters.” — Jeff PPC
Basic Information on the Tack Driver Shoot:
There are two divisions — bolt-action rifles and semi-auto gas guns. There are no specific design limits other than a 22-lb maximum weight, and a .338 maximum caliber. Past IBS President Jeff Stover tells us: “We envision the full array of the world’s most accurate rifles on the line: short and long range benchrest rifles, F-Class, AR, other tactical, egg-shoot rifles, whatever…[.]” Semi-autos required chamber flags, otherwise bolts must be out at all times.

Fire-Form with Foulers
IMR 8208 XBR powder is a great propellent that has shown superb consistency, delivering great accuracy and low ES/SD in our testing. We have used this powder with success in .308 Win and other cartridges. The burn rate is slightly slower than Vihtavuori N133 and a bit faster than Hodgdon H4895. IMR 8208 XBR is suitable for many cartridge types including .204 Ruger, 22 BR, .223 Rem, 6 PPC, 6BR (lighter bullets), and .308 Winchester. It works great for varmint hunting loads as well as benchrest competition.
