As a Christmas present for our readers, today we showcase eight very informative videos from AccurateShooter Forum member F-Class John. A talented F-Class competitor with a smart, technically-focused mind, John has created a series of videos about reloading and precision loading tools, along with rifle and shooting accessories. Many of John’s product reviews are the most thorough and detailed you’ll find in video format. You’ll find over 840 informative videos on F-Class John’s popular YouTube Channel.
This is a great summary of multiple quality front rests. This is a must-watch video for all F-Open and Benchrest shooters! If you are shopping for a front rest, definitely watch this comprehensive 42-minute video from start to finish. This is probably the most informative video about premium shooting rests available on YouTube. Top F-Class shooter and video-maker F-Class John covers a wide selection of front rests, with some observations about coaxial bipods as well. John covers the impressive new SEB NEO-X, the easy-to-transport SEB Mini-X, the excellent Rodzilla Rest, the innovative 21st Century Hybrid Rest, the sleek Italian Lenzi Rest. At the end of the video John reviews the very affordable Caldwell Fire Control Rest ($269.99 at MidwayUSA), explaining how it can be a decent choice for shooters on a limited budget.
How to Use a Barrel Tuner to Improve Accuracy and Repeatability
In this video, John works with a barrel tuner created by Erik Cortina, a member of Team Lapua/Brux/Borden. A tuner can be useful in modulating barrel vibrations and that can translate to smaller groups on target. Sometimes the positive effects are quite noticeable. Tuners have been popular with short-range benchresters for many years and now they are becoming more common on top F-Class and Long Range rifles.
John says: “I’ve been using Erik’s E.C. Tuner for a while now and I really like what it’s done to help as my final step in load development. Just remember, a tuner is a tool, not a magician. You still need good load development practices, good brass prep, and solid skills but the tuner does help make great loads even better.”
F-Class Rear Bag Setup: Fill Techniques for Ultimate Consistency
In this helpful video, F-Class John shows his process for filling high-quality Dima rear bags (both medium models). John explains how to select fill (based on weight and density preferences). He shows the different funnel systems that work very effectively. If you’re planning to invest in a quality rear bag for competition, this video will be useful, both in choosing appropriate fills and getting the fills into the bag efficiently.
21st Century Hydro Press and Arbor Press — Product Review
Many of the world’s top benchrest, long-range, and F-Class shooters prefer to seat their bullets using arbor-type presses with inline dies. This allows smooth, repeatable bullet-seating with very low run-out. One of the very best arbor-type seating presses ever created is the 21st Century Hydro Press. This offers plenty of leverage driving a precision ram. The Hydro Press also features a hydraulic line to drive a precision seating force gauge. Along with the Hydro Press, John tests 21st Century’s standard arbor press.
Accuracy One Concentricity Gauge — Product review
Every person who makes precision hand-loads should have a quality concentricity gauge to measure run-out of case-necks and loaded rounds. Here John tests one of the best such tools on the market, the Accuracy One Concentricity Gauge. This measures the internal and external neck runout of cartridge cases as well as seated bullet runout. It can also measure the runout of the ogive, bearing surface, and boat-tail of individual bullets and can even measure primer pocket runout. John notes: “I think most precision shooters should have one of these to make sure their ammo is within their specs they’re happy with.”
Henderson vs. Giraud Rifle Power Brass Trimmer Review
After adding the impressive Henderson Gen 3 Powered Trimmer to his inventory of tools. F-Class John became is a Henderson fan. He likes the speed, precision, and repeatability of the $439.00 Henderson machine, which trims-to-length and chamfers the case mouth all in one pass. Unlike some other trimming tools, the Henderson indexes off the overall case length NOT the shoulder. The $575.00 Giraud trimmer is a very different design which indexes off the case shoulder, but it is also very precise. When set up correctly, it can trim brass with amazing consistency. As long as you have fire-formed brass with consistent base-to-shoulder dimensions, you should get very consistent trim lengths.
SuperTrickler vs. AutoTrickler V4 Powder Measure Comparison
This video compares the elite SuperTrickler and AutoTrickler V4. The AutoTrickler system paired with a quality Force Restoration scale, is the “Rolls Royce” of electronic powder dispensing systems, offering unrivaled charge-weight accuracy, great repeatability, and ultra-fast dispensing speeds. If you have the budget — $490 for the V4 plus $720+ for A&D FX-120i scale — the AutoTrickler V4 is a superb system that lets you load extremely accurate, consistent ammo. This detailed F-Class John video compares the AutoTrickler with and all-in-one SuperTrickler scale/dispenser which also performs great. The SuperTrickler ST101 is $775.00 for ST101 Gen2 top unit only or the full unit is $1400.00 complete with FZ-120i scale.
Teslong Rigid 26″ Borescope with 4.5″ Monitor — Product Review
There are a variety of affordable Teslong digital borescopes for inspecting your barrels and diagnosing issues. All Teslongs deliver impressively sharp images/video. Some units plug into a laptop or tablet, while others work via a dongle to communicate wirelessly. Here John tests a 26″ rigid model borescope that comes complete with its own 4.5″ viewing screen. Priced at $149.99 on Amazon, this system is completely self-contained — you don’t need a laptop or smartphone. You don’t have to worry about connections and there are no Apps to install or configure. John says: “Teslong now offers a 26″ rigid rod model with a 4.5″ monitor. This allows you to use the unit without the need for any mobile device or computer.”
If you want to compete in top handgun competitions such as the CMP matches at Camp Perry, you’ll need good ammo that has low ES, consistent powder charge, uniform cartridge OAL, and consistent crimp. Every with action pistol matches you’ll want ammo that is very uniform. One miss on steel can mean losing a match. The following USAMU article provides rock-solid pistol reloading advice, explaining how to load accurate, reliable handgun ammo.
The U.S. Army Marksmanship Unit (USAMU) fields pistol teams as well as rifle and shotgun competition squads. Consequently the USAMU’s Reloading Shop loads tens of thousands of pistol rounds every year. In this article, the USAMU’s handgun experts talk about reloading for handguns — with smart tips on how to achieve superior accuracy with 100% reliability. This article, which offers important insights on COAL, primers, crimps and more.
Precision Pistol Reloading — Recommended Methods
Optimize the Taper Crimp
One often-overlooked aspect of handloading highly-accurate pistol ammunition is the amount of crimp and its effect on accuracy. Different amounts of taper crimp are used with various handloads to obtain best accuracy. The amount is based on bullet weight, powder burn rate and charge, plus other factors. It is not unusual for our Shop to vary a load’s crimp in degrees of 0.001″ and re-test for finest accuracy.
Use Consistent Brass
Brass is also important to pistol accuracy. While accurate ammunition can be loaded using brass of mixed parentage, that is not conducive to finest results, particularly at 50 yards. It is important for the serious competitor/handloader to use brass of the same headstamp and ideally one lot number, to maximize uniformity. Given the volumes of ammunition consumed by active pistol competitors, using inexpensive, mixed surplus brass for practice, particularly at the “short line” (25 yards), is understandable. However, for the “long line” (50 yards), purchasing and segregating a lot of high-quality brass to be used strictly for slow-fire is a wise idea.
Importance of Uniform COAL
Uniformity of the Case Overall Length (COAL) as it comes from the factory is also important to achieving utmost accuracy. More uniform case lengths (best measured after sizing) contribute to greater consistency of crimp, neck tension, ignition/burn of powder charge, and so on. Cartridge case-length consistency varies from lot to lot, as well as by maker. Some manufacturers are more consistent in this dimension than others. [Editor’s note: It is easy to trim pistol brass to uniform length. Doing this will make your taper crimps much more consistent.]
Primers and Powders — Comparison Test for Accuracy
Pay attention to primer brands, powder types and charges. Evaluating accuracy with a Ransom or other machine rest at 50 yards can quickly reveal the effect of changes made to handload recipes.
Bullet Selection — FMJ vs. JHP
Bullets are another vital issue. First, there is the question of FMJ vs. JHP. A friend of this writer spent decades making and accuracy-testing rifle and pistol bullets during QC for a major bullet manufacturer. In his experience, making highly-accurate FMJ bullets is much more difficult than making highly-accurate JHPs, in large part due to the way the jackets are formed. Small die changes could affect accuracy of FMJ lots dramatically.
The CMP now allows “safe, jacketed ammunition” in Excellence-in-Competition (EIC) Service Pistol matches, although wadcutter ammunition is prohibited. Thus, the option to use very accurate JHP designs simplifies the life of CMP Service Pistol shooters in pursuit of the Distinguished Pistol Shot badge.
Hopefully, these tips will be helpful to any pistol shooters interested in accurate handloads, not just “Bullseye” shooters. Small tweaks to one’s normal routine can pay big dividends in improved accuracy and make practice and competition more rewarding. Stay safe, and good shooting!
Many visitors to the site ask us, “I’ve got a .223 and .308. What will a 6mmBR Norma (6BR) give me that I’m not getting already?” Well first you will probably average consistently smaller groups than your current .223 or .308 rifle (assuming the 6BR has a quality barrel and trigger). A good .308 Winchester can be superbly accurate, no question about that, but the lesser recoil of the 6BR works in the shooter’s favor over a long string of fire. Even with a Rem 700 or Savage action factory action, a 6BR with a benchrest stock, premium barrel, and a high-quality chambering job should deliver 5-shot groups in the high twos to mid-threes, provided you do your job. We have one 6BR rifle that shoots Lapua factory-loaded 6BR ammunition in the low twos and high ones. That’s exceptional, we admit, but it still shows how the 6BR is an inherently accurate cartridge, even with factory loads.
Compared to a .223, the 6BR offers a much better selection of high-BC projectiles, and will deliver considerably more power on the target. So it’s a better choice for hunters and 600-yard benchrest shooters. Compared to the .308 Win shooting 168gr MatchKings, a 6BR shooting 105-107gr bullets offers better ballistics all the way out to 1000 yards. Plus, for most people, the 6BR is just easier to shoot than a .308 Win. Recoil is less than half of the .308 Win cartridge. Both the .308 and 6BR chamberings offer good barrel life, but the 6BR uses 15-18 grains less powder, saving you money. On the other hand the .308 Win is the designated cartridge for F-TR and Palma shooting, so it may be a more versatile chambering for Long-Range competition. So which would we choose between the 6BR and the .308? Actually we think you should have both. The 6BR is a favorite cartridge out to 500 yards, and we like the .308 Win for F-TR. The .308 Win has shown outstanding accuracy, as displayed last week at the NRA F-class Nationals in Arizona.

The Cartridge Comparison Guide is a remarkably comprehensive 340-page, spiral-bound book. Covering over 250 cartridges, the Second Edition of the Cartridge Comparison Guide is the product of many years of labor by Andrew Chamberlain, a Utah-based hunter. Andrew says his Guide “compares every factory available cartridge from the 17 calibers up to the 50 caliber cartridges”. (Sorry, most wildcat cartridges are not covered.) Chamberlain’s Guide also compiles cartridge data from major ammunition manufacturers such as Barnes, Federal, Hornady, Norma, Nosler, Remington, Sierra, Swift, Weatherby, and Winchester. It shows the optimal velocity achieved for each bullet weight and calculates bullet energy, recoil, and powder efficiency. Large color photos illustrate handgun and rifle cartridges.
The Cartridge Comparison Guide provides data for thousands of cartridge/bullet/velocity combos. Quick reference sheets and ballistics charts cover Trajectory, Velocity, and Energy out to 500 yards. The Cartridge Comparison Guide also offers a firearms lexicon, plus Appendices covering Cartridge Selection for Game Animals, Bullet Selection/Design, Bullet Expansion, and Wound Channel Characteristics.

Over 90 pages of additional ballistics content (roughly 35% more than in First Edition).
Great Resource for Hunters
One of Chamberlain’s main goals in creating the Cartridge Comparison Guide was to help hunters select the right cartridge for the job: “This started as a personal project to gather information on the more popular cartridges commonly used for hunting. I wanted to find the best all-around performing cartridge and rifle that a guy on a budget could shoot. I began comparing cartridge performance, versatility, bullet selection, powder efficiency, recoil generation vs. energy produced, standing ballistic data for different environments….”

Sinclair International has created a series of instructional videos illustrating the basics of metallic cartridge reloading. The 8-Part series starts with reloading basics and provides step-by-step, how-to instructions that will help new reloaders get started. Detailed, animated illustrations show you what happens inside the chamber when shooting, and inside the dies during each step of reloading. The videos can be viewed on Sinclair International’s YouTube channel. Shown below is the first video in the series:
Each of the Sinclair videos is hosted by then Sinclair Int’l President Bill Gravatt (now with Creedmoor Sports). Bill doesn’t just show you “how”, he tells you “why”. The how-to segments cover case inspection, proper die set up, case sizing, primer installation, powder measuring, bullet seating, crimping, and even goes into the record keeping needed for the handloader. “We wanted to give shooters who haven’t reloaded a look at all the advantages of creating your own ammo and how easy it is to get started,” said Gravatt, “without telling them they had to have any certain brand or type of equipment to do the job.”
The Eight Video Topics Are:
Part 1 — Intro to Video Series
Part 2 — Intro to Reloading Safety
Part 3 — Metallic Cartridge Components
Part 4 — The Firing Sequence
Part 5 — Tools for Reloading
Part 6 — Loading Bottle-Neck Cartridges (2 videos)
Part 7 — Loading Straight Wall Cartridges
Part 8 — Reloading Series Conclusion
Reloading Tools
Shown below is Part 5 of the video series, covering the tools used for precision reloading.
We also strongly recommend the Part 4 Video to readers who are getting started in reloading. This “How Things Work” segment covers the sequence of events inside the chamber (and barrel) when the cartridge is fired. The video includes helpful graphics that show what happens to the primer, powder, cartridge, and bullet when the round is fired. The video also illustrates “headspace” and explains how this can change after firing. We think this video answers many common questions and will help reloaders understand the forces at work on their brass during the firing process.
Photo shows Bryan Litz (on right) and tester Mitchell Fitzpatrick. Bryan said: “Only 2,445 rounds to go! We’re testing over 50 ammo types in five different twist barrels… science can be exhausting!”
Do you know the actual BC (Ballistic Coefficient) of your rimfire ammunition? Well Applied Ballistics has the data, thanks to a comprehensive, marathon ammo testing session. Some years back, in an effort to determine the “real world” BCs of various rimfire ammo types, Bryan Litz and his team at Applied Ballistics did an extraordinary, in-depth shooting test. Litz and company tested over fifty types of .22 LR ammo, using five different twist-rate barrels. This was one of the most comprehensive and through rimfire ammo tests ever done.
Bryan tolds us: “We tested many types of .22 rimfire ammo for the 2nd Edition of the Ballistic Performance of Rifle Bullets book. We used a pair of Oehler chronographs to measure velocity at the muzzle (MV) and velocity at 100 yards.” With these numbers (average and SD) Bryan can calculate G1 BCs for all the 50+ types of rimfire ammo. What’s more, because every sample is shot through five different barrels (each with a different twist rate) Bryan can also determine how velocity is affected by twist rate.
The tests are primarily to determine velocities for BC calculations — this was not an accuracy test. Bryan explains: “Our tests are not really looking at accuracy, mainly because that’s so subjective to different rifles. Our testing is primarily focused on measuring the BC of rimfire rounds from different twist-rate barrels. The MVs and BCs from the different twist test barrels was then published by Applied Ballistics in print books. Bryan Litz told us: “The .22 LR Rimfire data was originally published in Ballistic Performance of Rifle Bullets, 2nd Edition, which is now out of print. The 3rd Edition of that book doesn’t have rimfire data. The rimfire testing results and data were re-published in Modern Advancements in Long Range Shooting – Volume II (along with many other topics).
Bringing Science to the Rimfire World
Bryan’s goal with this project was to increase the rimfire knowledge base: “We hope to give the world of .22 LR rimfire a good dose of science. How is the BC of .22 rimfire ammo affected by barrel twist? Do subsonic rounds have more consistent BCs than supersonic or transonic rounds? What brands have the highest BCs? What brands have the most consistent MVs?”
Data from two Oehler chronographs is recorded in a computer. Ammo samples were tested in five (5) different barrels (of varying twist rates). Give credit to Dane Hobbs who supplied a test rifle, multiple barrels, and most of the ammo types for the test.
.22 LR at 300 Yards?
Bryan also conducted some longer range rimfire tests. His interesting findings have appeared in the Modern Advancements in Long Range Shooting book series. Bryan notes: “While .22 rimfire isn’t typically considered ‘long range’, we were able to consistently hit a two-MOA steel target at 300 yards with the trajectory predicted by AB software and the measured BC of some standard .22 LR rimfire ammo. The info we’’re generating may make it possible to push the range of target engagement for a round that’s not seen much advancement in many decades.”
Product innovation is all about “building a better mousetrap”, or in this case, building a better bore-cleaning patch. A real smart guy, Shane Smith, has invented a triangular patch that earned a patent. The U.S. Patent Office has awarded a utility patent for BoreSmith’s Triangle Patch™. This unique cleaning patch was designed by Shane Smith, a mathematician/physicist who employed his scientific and firearms knowledge to create innovative bore-cleaning products.
BoreSmith’s Triangle Patch™ (aka Pyramid Patch) presents more cleaning surface area to the bore wall than does a conventional square or round patch (of equivalent size). At the same time, the unique geometry makes Triangle Patches much less likely to jam in the barrel. This is because the notches in the sides of the triangle allow the patch to sit more uniformly on the jag (without bunching up). Also the Pyramid patch is much less likely to jam due to pleating. One reason conventional patches get stuck is unwanted 5-layer pleating. The special notches in the Pyramid patch remove all or most 5-layer pleating. As a result the patch does not bunch up and this also reduces rod bowing.
Triangle Patch Function and Geometry Explained (See 1:18 time-mark):
NOTE: Despite what you may see in this video, you should ALWAYS insert brushes and patches from the chamber end first, using a fitted cleaning rod bore guide. With bolt-action rifles, NEVER insert a cleaning rod (with brush or jag) in through the muzzle. This may damage the delicate crown of your barrel.
The Triangle Patches work great with Boresmith’s patented dual-diameter bore brushes:
