Saturday at The Movies — Cartridge Comparison Collection

caliber cartridge video showcase reviews cgi .22 LR flat-shooting

For today’s Saturday at the Movies special, we provide a selection of videos showcasing rifle and pistol cartridge types — from tiny .17 caliber cases to huge 20mm cases. Two of the videos use advance computer animation to provide 3D views of dozens of cartridge types. Then there are some expert commentaries by Jerry Miculek and Ron Spomer discussing the characteristics and performance of various cartridge types. Finally, we provide two videos that discuss rimfire cartridges and show how .22 LR rounds are produced in a modern CCI factory.

90 Different Rifle Cartridge Types in Computer Animation

In this rifle ammunition comparison animation there are 90 different cartridge types, from very small (.22 Flobert) to very, very big (20mm Vulcan). This video employs sophisticated, 3D CAD animation to showcase 90 different rifle cartridges, one after the other, in sequence. It covers from .17 Caliber up to 20mm. Obviously a lot of time and effort went into this video, but it really is cool to see so many different cartridge types in one 3.5-minute video.

Big Bore Brilliance — Paul Phillips Optimizes the .416 Barrett

global precision group ELR .416 barrett RCC machined brass 500 yards solid Cutting Edge bullets

Paul Phillips Ko2mPaul Phillips is a past King of 2 Miles, and one of the world’s top Extreme Long Range (ELR) Shooters. He recently showcased one of his ELR rifles that shoots the .416 Barrett cartridge with huge, 550gr Cutting Edge bullets seated in CNC-machined RCC (Robertson Cartridge Company) brass that costs $10 per case.

Even with these giant-sized cartridges, Paul Phillips is getting remarkable accuracy. He recently went out to a snow-covered rifle range to do some testing. We include some test results in this article. Paul’s rig delivered 1.056″ to 1.748″ 3-shot groups at 500 yards. That’s .202 to .335 MOA for three shots. (1 MOA = 1.047″ at 100 yards, or 5.235″ at 500 yards). That’s very impressive accuracy for such a big cartridge with serious recoil.

Confidence is Gained from Consistent Accuracy

Report by Paul Phillips
After being retired from my 30 years of service in military and law enforcement, I started my own company, Global Precision Group LLC. We specialize in Long range shooting. I am currently doing some R&D for a new ammunition company, Ultimate Ammunition, (UA) out of Las Vegas. UA specializes in Military, Law Enforcement, and Custom ammunition.

global precision group ELR .416 barrett RCC machined brass 500 yards solid Cutting Edge bullets

On this particular day, it was a very cool 15 degrees F. I was testing ammunition for the .416 Barrett. Since winning the King of 2 Miles in 2019, my team has been looking at ways to make everything better. The competition is fierce and everyone is getting better and better. Finding single-digit Standard Deviations (SDs) is a must. Holding SDs under 5 FPS can be what it takes to win.

global precision group ELR .416 barrett RCC machined brass 500 yards solid Cutting Edge bulletsAfter several weeks of testing, I think I found the perfect combination for the .416 Barrett in my rifle. My optimal load runs about 3000 FPS using the following components:

Cutting Edge 550 Grain Solid Bullets with Tips

RCC Brass (CNC-machined)

Vihtavuori 20N29 Powder

RWS primers

Loaded for ~3000 FPS load velocity goal

I figure if I can keep my 3-round groups under two inches consistently, I have a chance to win on any Sunday. The average group size of these groups was 1.47 inches at 500 yards. With big bore rifles it gets very costly to test. That is why I am limiting my test groups to 3 rounds. See below:

global precision group ELR .416 barrett RCC machined brass 500 yards solid Cutting Edge bullets

Note the single-digit Extreme Spread and SD for all of these three-shot groups, as recorded by the LabRadar (see below). The average SD for these three groups at 500 yards was about three.

Not just the ammunition deserves credit. I also have to give credit to the quality Manson reamer, BAT action, Bartlein Barrel, Bix’N Andy trigger, Manners ELR stock, Nightforce Optic, and Accu-Tac bipod with my new P skis. All these gear/hardware items, combined with quality ammunition, allow these kind of groups.

Look INSIDE Remington 700 with “X-Ray” Computer Graphics

3d firearms modeling gun CGI software encylopedia gun disassembly

Ever wish you could look inside your rifle, to see how the trigger and fire-control system work? Well now that is possible with the magic of 3D computer graphics. Modern software allows detailed “cutaway” side-views (see below), as well as 3D views with 360° rotation. The software can also provide X-Ray-type views into the gun’s internals — as you can see above. And computer animation can show the complete firing process from trigger pull to chambering of the next round.

Rem 700 Cutaway View from Right Side
3d firearms modeling gun CGI software encylopedia gun disassembly

This article provides some very cool 3-D “Cutaway View” animations of the popular Remington 700 action, probably the most successful American bolt-action ever created.

READERS — Take the time to watch the video! The Rem 700 animation is really outstanding! EVERY bolt-action shooter should watch this video all the way through.

Cutaway 3D Animation of Rem 700 Action — Watch Video

The Model 700 series of bolt-action rifles have been manufactured by Remington Arms since 1962. All are based on basically the same centerfire bolt action. They are typically sold with an internal magazine depending on caliber, some of which have a floor-plate for quick-unloading, and some of which are “blind” (no floor-plate). The rifle can also be ordered with a detachable box magazine. The Model 700 is a development of the Remington 721 and 722 series of rifles, which were introduced in 1948.

3d firearms modeling gun CGI software encylopedia gun disassembly

The Remington 700 is a manually-operated bolt action with forward, dual opposed lugs. It features “Cock On Opening”, meaning the upward rotation of the bolt when the rifle is opened cocks the firing pin. A cam mechanism pushes the firing pin’s cocking piece backward. The bolt face is recessed, fully enclosing the base of the cartridge. The extractor is a C-clip sitting within the bolt face. The ejector is a plunger on the bolt face actuated by a coil spring. The bolt is of 3-piece construction, brazed together (head, body. and bolt handle). The receiver is milled from round cross-section steel.

3d firearms modeling gun CGI software encylopedia gun disassemblyThis video was made with the help of the World of Guns: Gun Disassembly interactive encyclopedia with 3D rendering. This remarkable web-based software allows users to view the inner workings of hundreds of different rifles and pistols — everything from a .22 LR Ruger to a .55-caliber Boys Anti-Tank rifle. There are also 25,000+ parts diagrams. This is a remarkable technical resource. SEE MORE HERE.

Saturday at the Movies: Ultimate Reloader Product & Tech Videos

YouTube Ultimate Reloader Video Showcase BAT action AMP Press reloading T-7

Gavin Gear, founder of the UltimateReloader.com website, has created a very popular YouTube Channel. Over the past 14 years, Gavin has produced hundreds of videos covering nearly every aspect of reloading, rifle assembly, and gunsmithing. When important new reloading products are released, you’ll often find that the very first, in-depth reviews come from Gavin. He seems to get the new stuff before ANYone else.

Gavin’s Ultimate Reloader videos are very professional, with high-quality lighting and audio, multiple camera angles, and careful editing. And unlike many of the YouTube video hosts, Gavin is also a talented shooter and skilled gun-builder. His shop is complete with modern lathes, mills and other tools so he can build his own very accurate rifles from start to finish.

BAT Machine Modular Bolt — Design Features and “How To”

With most rifle actions, if you want to run a variety of cartridges with different case head diameters, you will need multiple bolts. However, there IS an alternative to purchasing multiple pricey bolts. BAT Machine has come up with a great solution for the bolt face issue — the Modular Bolt System. In this video Gavin explains how the Modular Bolt System works. He explains the design, then shows, step-by-step, the entire process for swapping bolt head sizes. With a bit of practice, this can be done easily in a couple minutes. Showing a bolt head swap start to finish (00:50 — 2:15 time mark), Gavin shows how to use the BAT Bolt Disassembly Tool and BAT Sleeve Removal Tool to complete the task quickly and easily.

AMP Inline Press — Effect of Brass Prep and Neck Chamfer

In this video Gavin examines various cartridge brass prep processes, and then used the advanced, computer-controlled AMP press to determine how those processes affect bullet seating forces/consistency. Gavin noted: “Each process is examined and a graph is presented of the bullet seating forces. We anticipated some of what we saw, and were surprised by other things.” The computer-controlled AMP press provides a graph of the exact seating forces, allowing to improve your brass prep to achieve the most consistent seating. Gavin notes: “Lately we’ve been seeing the AMP Press used for tight quality control from precision reloaders around the world.”

In this follow-up video, Gavin employs the advanced AMP press to examine how case neck chamfering affects bullet-seating force and consistency. Gavin tells us: “In this video, we single out one variable: Chamfering Case Mouths.”

Creedmoor Sports TRX-925 Scale Review

This is NOT a magnetic force-restoration scale, but it is one of the best strain-gauge scales you can buy. And, priced at $349.95, the Creedmoor Sports TRX-925 Precision Reloading Scale costs less than half what a good force-restoration scale costs. That’s a big deal for folks on a budget. This TRX-925 scale offers very good performance for the price. We include a second, detailed, 25-minute review by F-Class John who says the TRX-925 offers excellent performance for the price. F-Class John, who has his own popular YouTube Channel, produces very comprehensive, thorough product reviews.

This Second TRX-925 Video is from F-Class John:

Finding Cartridge Length to Lands in your Barrel — Three Methods

In this video, which has over 250,000 views on YouTube, Gavin shows three (3) different methods to determine length to lands (L-to-L). This means you are finding the exact length of a case with bullet when the bullet first contacts the rifling in the barrel. It is important to determine this dimension with repeatable precision, so you can tune your load length for best accuracy. In addition, in some disciplines you’ll want to avoid seating into the lands.

Creedmoor Enhanced Press Head for Redding T-7 Press


Creedmoor sports redding t-7 enhanced turret head press

The new Creedmoor Enhanced Press Head for the Redding T-7 Turret Press is a direct upgrade that offers many advantages for precision, ease of use, and reloading. Made from solid 416 Stainless Steel, this Press Head boasts precision cut threads, integral detent/track system, and seven threaded handle position. Creedmoor states: “A machined stainless steel head, rather than one made from cast steel, allows for tighter tolerances, an improved surface finish, and ultimately makes a better product for our customers.” The Redding T-7, already a good turret press, functions better with this press head, which is precision-machined to ensure flatness of both upper and lower surfaces. The Enhanced Press Head, which can be installed in a matter of minutes, is available now from Creedmoor Sports for $179.95.

.223 Rem vs. 5.56x45mm — 6.3 Million Views

This video explains essential facts and corrects common misconceptions related to both .223/5.56 ammunition, as well as .223/5.56 rifles. Gavin provides insight on chamber specs, pressure levels, barrel twist rates, military 5.56 crimped brass, and other important topics. If you are new to the AR world, this video is definitely worth watching. And that’s why it now has garnered over 6.3 MILLION YouTube views, making it one of the most popular gun-related videos ever made. Gavin adds: “Don’t forget to check out the full write-up on UltimateReloader.com.” CLICK HERE for FULL STORY.

Lake City Ammunition Production Start to Finish Video

lake city army ammunition plant

Lake City Ammunition PlantWhat’s the next best thing to a stockpile of gleaming, freshly-loaded ammo? How about a movie showing gleaming, freshly-loaded ammo being made — from start to finish? The five-minute video below shows the ammunition production process at the Lake City Army Ammunition Plant in Independence, Missouri. Lake City is the largest producer of small arms ammunition for the U.S. military, producing roughly four MILLION small-caliber rounds every day.

This promotional video does go overboard at times (too many smiling employees gushing about quality control). Still, it is fascinating to watch the process of creating cartridges — from the drawing (or extrusion) of raw brass into casings to the placement of projectiles and primers.

Lake City Ammunition Plant

Quick History of Lake City Ammunition Plant
Lake City Army Ammunition Plant (LCAAP) is a 3,935-acre government-owned, contractor-operated facility in Independence, Missouri that was established by Remington Arms in 1941 to manufacture and test small caliber ammunition for the U.S. Army. The facility has remained in continuous operation except for one 5-year period following World War II. Remington Arms operated the plant from its inception until 1985. Then Winchester took over the facility from 1985-2000.

Prior to its acquisition by Northrup Grumman in 2018, Orbital-ATK ran the plant since late 2000, initially as Alliant Techsystems (ATK). Recently Olin Corporation announced that its ammunition division, Olin Winchester, LLC, has been selected by the U.S. Army to operate and manage the Lake City Army Ammunition Plant for the next seven years — Winchester will assume full operational control of the Lake City plant on October 1, 2020.

Erratic POI? Check Your Scope — But It Could Be a Loose Barrel

loose barrel vortex scope optics point of impact change fix

Are you seeing unpredictable changes in Point of Impact on your target? Think you may have a scope issue? Well maybe not — when was the last time you checked your BARREL?

Yes scopes do fail, and scope bases/rings do get loose. But sometimes problems with erratic POI shifts are caused by a LOOSE BARREL. This issue came up recently in our Shooter’s Forum. One member complained that his zero was shifting from day to day — by as much as two inches at 100 yards. He was convinced he had a scope problem, based on erratic POI:

“I think my scope loses 1 to 3 MOA per day. When I shot my rifle Monday it was dead on. On Tuesday it was 1″ low. Then on Wednesday it was 1 or 2″ lower. I don’t get it. — the elevation knob never touched. Scope will track and return to zero that day perfect. Yes EVERYTHING has been checked, nothing loose. What is the chance the erector tube spring has gone south? For the record this is a Vortex GE. Never had a bad scope, but this has me wondering”. — LB

On Forum member told LB to send the scope right back to the manufacturer. Two other members suggested mounting the scope on a different rifle to test. Good advice. That’s generally a smart strategy before you conclude a scope has gone bad…

Could Problem Be the Scope Base?
Two Forum members, ExPiper and Dickn52, suggested checking the scope base, recounting their past experiences with troublesome bases. This was intelligent — anyone with a POI problem should check all the optics attachments:

“Went crazy one day chasing my impacts on a 100-yard target. Shots would group fine for three then go nuts for 4-5. I cranked and un-cranked for about an hour. Then I reached up and the base wobbled on the rifle. Removed scope, tightened base screws and back in business.” — Dickn52

“Years ago I had a problem [where] shots were climbing with almost every shot. I was blaming the scope. However, when removing the scope I noticed that the 20 MOA base was cracked and getting wider with every shot. Needless to say I replaced the base and the problem was solved. — ExPiper

Eureka Moment — The problem was the BARREL, not the Scope

There were many helpful suggestions, but member PirateAmmo steered LB to the real problem — a loose BARREL: “We had a problem on a home-built AR-platform rifle once, barrel was loose a tad…”

Member Snert chimed in: “Yep — I had a PPC that suddenly went 19″ low. Picked up gun off bench by barrel and felt a wiggle. I tightened the barrel and the POI went 19 inches up”.

Problem Solved — Barrel Tightened up and POI Back to Normal
The gentleman with the POI problem took the advice of PirateAmmo and checked his barrel. BINGO! Low and behold, the barrel WAS loose.

LB posted: “Barrel loose by about 2%, checked it twice before and didn’t find it the first two times”.

After LB re-tightened his barrel, his rifle started shooting normally again. No more shooting low by 1-2 inches. Problem solved. The fix didn’t cost a penny and now LB doesn’t have to send a perfectly good optic back to the manufacturer.

Lesson learned? Check ALL the variables before you assume a scope has gone bad. Along with the barrel, also check your action screw tension, and of course the scope base and rings.

Howard Leight Quiet Band qb2 hearing protection earband ear

Howard Leight intra-aural inner-aural ear plugs ear band hearing protectionEffective hearing protection is a must whenever you are shooting firearms or when you are in the vicinity of gun-shots. For ultimate protection, we recommend a good set of tapered foam earplugs, topped by muffs. However, there are situations when you may prefer lighter-weight hearing protection that can be quickly removed. For example, if you are standing well behind the firing line as an observer, or if you are working as a rangemaster or waddie some distance away from the shooters. In addition, game hunters may only need hearing protection for a few moments when they take their shot, so something light-weight that can be deployed in seconds is ideal.

In addition to traditional ear plugs and ear-muffs, band-style protectors provide a third sound-blocking option. Howard Leight, a top name in the sound-protection business, offers the popular “Quiet Band”, a device with soft foam plugs attached to a plastic band worn around the neck. This “Quiet Band” product is comfortable, easy-to-deploy, and surprisingly effective.

NOTE: We do NOT recommend these for normal, sustained use when shooting firearms, as when shooting a match. Use muffs over plugs for that. However, Quiet Bands work very well if you are spotting for a fellow shooter, or are near the firing line. These also work great when running noisy machinery such as leaf-blowers.

Howard Leight Quiet Band qb2Three Quiet Band Models
There are three (3) types of Leight Quiet Band® sound protectors. We prefer the QB2 Supra-aural model (item QB2HYG, NRR 25).

The recommended QB2 Quiet Band positions cone-shaped foam pads next to the ear openings and holds them there with light pressure from the orange-colored band. There is also an Inner-aural version (item QB1HYG, yellow band, NRR 27), and a Semi-aural model (item QB3HYG, red band, NRR 21).

Our preferred QB2 Supra-aural (orange band) model is just as comfortable as the QB3 (red band) version, and offers much better protection. The QB1 Inner-aural (yellow band) model requires that you place the ear buds in the ear canal, so it’s not really any easier to use than conventional earplugs. That’s why we like the QB2 Supra-aural model best of all. Other users agree. Here’s what two QB2 owners had to say:

Hickok45 leight qb2“I first saw these used by Hickok45 on YouTube and he talked positively about them. I got two and gave them a try. At first, I didn’t think they were going to work very well. After some fiddling, I found they work pretty darn good. With my ears, they fit the best if the band starts on top of my head, I insert the plugs then rotate the band behind my head. PRESTO, perfect fit. Shooting the 9mm and 12 gauge out back was comfortable with no ringing afterward. [They are] small and easy to transport — just throw in the range bag. Yet, they are big enough to keep around your neck out of the way[.] I highly recommend them to anybody needing banded hearing protection.” — Tom W.

“Great for woodworkers — These are lightweight AND very effective at reducing noise. When not in use the band hangs loosely around your neck, out of your way completely. Very cost effective for a great product!” — Sheri D.

Quiet Bands Are Much Less Expensive Than Earmuffs
Quiet Band® sound protectors can be purchased online for under $6.00 per set. We like the QB2 Version which comfortable and easy to put in place. These currently cost $5.99 for one set or $11.48 for three QB2 bands with 3 extra sets of plugs. Alternatively, you can get the Leight QB3 Supra-Aural for $5.00 or the Leight QB1 Inner-Aural for $4.96. The QB3 features a flatter ear pad while the QB1 is designed the insert in the ear canal like conventional plugs. We think the QB2 is the best choice for most users.

For QB1, QB2, and QB3 ear bands, replacement ear buds are available and sold by the pair. You can also buy a Ten-Unit Bulk Pack of QB2 Quiet Bands for $45.50 with free shipping. If you run shooting matches or training programs, you can buy these in bulk for your Range Officers and pit workers. And there is a similar Sellstrom Banded unit with blue plugs for just $3.46 on Amazon.

Sunday Gunday: The Smallest 100-yard 5-Shot Group in History

world record Michael stinnett group .0077
Look and be amazed! In competition, a rifle drilled FIVE perfectly-overlapped bullet holes — the last virtually indistinguishable from the first — at a target a football field (100 yards) away.

Today we feature a benchrest rifle that earned its place in history by setting a small-group record in 2013 that may never be broken. This .30-caliber benchrest rig shot a 0.0077″ five-shot group at 100 yards. That’s the smallest 100-yard group ever shot in competition by ANY gun at 100 yards in history. And we may never see anything smaller in our lifetimes.

Record .008 .0077 group rifle

In setting that .0077″ (seventy-seven ten-thousandths of an inch) record, the shooter, Mike Stinnett, broke a record that stood for four decades — the 0.009″ five-shot group credited to Mac McMillan. The previous NBRSA Light Varmint Record of .009″ for five shots (at 100 yards) was set on 9/23/1973, 49 years ago. Experts considered that record “untouchable”, “unassailable” — in other words “unbreakable.” But Mike broke Mac’s record 40 years after it was set.

The Record-Setting Rifle and Cartridge
The gun that produced the historic .0077″ group was a Light Varmint-class Benchrest rifle chambered as a .30-caliber wildcat, the 30 Stewart. That cartridge is based on the 6.5 Grendel case necked up. The load had Hodgdon H4198 powder behind BIB 114gr, 10-ogive bullets. Notably, the record-setting ammo was pre-loaded before the match.

The Smallest 100-yard Group in History

All target shooters strive for perfect shot placement. Well one man has come closer to perfection than any other shooter who ever lived. You are looking at Michael Stinnett’s .0077″ NBRSA world-record group, the smallest 100-yard 5-shot group ever shot in the history of rifle competition. The group was certified at .0077″ (though labeled .008″ on the range-signed target below). A moving backer verified that this was FIVE shots — no question about that. You may be surprised but this was NOT shot by a 6 PPC, but rather a .30-caliber wildcat, based on the 6.5 Grendel.

Group Is Smaller than ANY 100-yard Group Shot in ANY Class

Mike’s amazing group stands as a NBRSA Light Varmint Class record. But it is also smaller than the current NBRSA 5-shot, 100-yard records for ALL other classes, even Unlimited (Rail Gun). Likewise Stinnett’s .0077″ group is smaller than the IBS records for ALL classes:

Official Benchrest 5-Shot 100-Yard World Records
Sanction Light Varmint Heavy Varmint Sporter Unlimited
NBRSA 0.0077″ Mike Stinnett 0.027″ Ralph Landon 0.041″ Jerry Thornbrugh 0.049″ Gary Ocock
IBS 0.051″ Mark Shepler 0.052″ J. Ventriglia 0.060″ J. Neary 0.045″ Gary Ocock


All NBRSA Group Size Records | ALL IBS Group Size Records

Better than any Rail Gun too — Mike Stinnett’s .0077″ group was smaller that ANY group shot in ANY class — event Unlimited Rail Guns, as shown below:

Below is a larger-than-life-size view. Using this photo we measured the group with target-calculating software, and it came out .006″ (the software only goes to three digits). We recognize that it would be much better to work from the real target rather than a photo, so we are not challenging the official measurement in the least. But this does confirm that this is a phenomenally small five-shot group.

Stinnett Sets .0077″ Record with a .30-Caliber Modified Grendel Cartridge, Pre-Loaded
Many folks have asked about the gun and ammo that produced the .0077″ group. The rifle was chambered as a .30-caliber wildcat, the 30 Stewart, which is based on the 6.5 Grendel case necked up. Mike was using Hodgdon H4198 powder behind BIB 114gr, 10-ogive bullets. Notably, the record-setting ammo was pre-loaded before the match. Unfortunately, we don’t have a photo of the target yet — it is still in the hands of the official NBRSA certification committee. However, Mike has been kind enough to tell us about his rifle and his load.

Mike Stinnett .0077″ Record Group Equipment Report

Mike reports: “Several guys have asked so here is my equipment listing. The hardware build actually started in 2008 with the goal of building two identical Benchrest rifles which could be used for both group and score. The idea was to shoot 6PPC and a .30 Cal without a base rifle change.”

Record-Setting Rifle Equipment and Components

Action: Kelbly Panda “Speedy Shorty” with solid bolt and PPC-diameter bolt face. Kelbly was asked to build several actions which were identical with the intent to eliminate any variance in head space between the two new rifles. This helped me use a single set-up on sizing dies for both rifles and ammo is interchangeable. Both actions were sent to Thomas ‘Speedy’ Gonzalez to be blue-printed and have Jewell triggers installed.

Reamer: 30 STEWART (I just call it a 30 PPC as that is what everyone expects, but it is in fact a custom design and Ralph deserves about 99% of the credit).

Barrels: Krieger was selected for the barrels. After discussions with Randy Robinett of BIB Bullets, a 1:17″ twist was identified as the correct, safe solution. Ralph Stewart has cut all my chambers using a custom-designed reamer. [Our goal] was consistent headspace and Ralph has been able to keep my barrels within .0002 variance. The barrel tuner also comes from Ralph Stewart.

  • Stock: Larson (including action bedding)
  • Scope: Leupold 45X Competition in Kelby Single Screw Tall Rings
  • Brass: Lapua (Base case is 6.5 Grendel)
  • Bullets: Randy Robinett (BIB) 30 Cal. 114gr, 10 Ogive (secondary bullet; primary is 112gr BIB)
  • Powder: H4198 – Stout Load with 2980 FPS Velocity
  • Front Rest: Farley Coaxial
  • Bags: Micro Fiber
  • Flags: Graham Wind Flags (large)

About the Cartridge — 30 Stewart (Based on Lapua 6.5 Grendel Parent Brass)
Mike explains: “Our goal was to shoot H4198 as the optimal powder for stability. There were several versions of the reamer before we settled on the current configuration. I am optimized for the 10 Ogive BIB bullet, powder to the base of the bullet. I found in testing the small 30-cal case did not like compression at all. The bullet is seated only 0.12″ into the case with zero freebore.

Cases were initially created with the .220 Russian (like a PPC) but I later decided it was better to build from the 6.5 Grendel. I size the brass and bump the shoulder back until it will fit into the chamber, fill to shoulder with International Clays, cotton wad packed on top. I have a fire-forming barrel. (I would not recommend this Clays and cotton wad method in a good barrel.) After initial fire-forming, I then mandrel the neck up the rest of the way to .30 caliber, turn the necks and trim.

It takes at least 8 firings to fully form a case! If you fire only three loads I find the brass does not have a sharp shoulder or any pressure on the bolt so any die selection is incorrect. Brass continues to harden well past 25 firings. I have match brass with well over 500 rounds fired, and I have never blown a case or neck yet (using my forming method).

For loading I use a Hornady Custom Shop Sizing Die and a Ralph Stewart Custom Seating Die. For those who are curious, yes the small group was fired with pre-loaded rounds. I do this now and then with local matches or may load 50 in a batch for one match.”

Mike wanted to thank his smiths, Randy Robinett, and all the folks involved in running the matches: “A big THANKS — as these are the guys that make our matches possible and without question maintain the integrity of the targets and record system. I was very fortunate to have all the right people in the right places for this match and my record. As for measurement – I only saw the target for about 10 seconds up close and can say I’m very happy I did not have to measure that group! Thanks again to everyone!” — Mike Stinnett

If You’re Not Using Wind Flags You’re Throwing Away Accuracy


Forest of Windflags at World Benchrest Championships in France in 2011

There’s a simple, inexpensive “miracle device” that can cut your groups in half. If you’re not using this device, you’re giving away accuracy. The “miracle device” to which we refer is a simple wind indicator aka “windflag”. Using windflags may actually improve your accuracy on target much more than weighing charges to the kernel, or spending your life savings on the “latest and greatest” hardware.

Remarkably, many shooters who spend $3000.00 or more on a precision rifle never bother to set up windflags, or even simple wood stakes with some ribbon to show the wind. Whether you’re a competitive shooter, a varminter, or someone who just likes to punch small groups, you should always take a set of windflags (or some kind of wind indicators) when you head to the range or the prairie dog fields. And yes, if you pay attention to your windflags, you can easily cut your group sizes in half. Here’s proof…

Miss a 5 mph Shift and You Could DOUBLE Your Group Size

The table below records the effect of a 5 mph crosswind at 100, 200, and 300 yards. You may be thinking, “well, I’d never miss a 5 mph let-off.” Consider this — if a gentle 2.5 mph breeze switches from 3 o’clock (R to L) to 9 o’clock (L to R), you’ve just missed a 5 mph net change. What will that do to your group? Look at the table to find out.

Imagine you have a 6mm rifle that shoots half-MOA consistently in no-wind conditions. What happens if you miss a 5 mph shift (the equivalent of a full reversal of a 2.5 mph crosswind)? Well, if you’re shooting a 68gr flatbase bullet, your shot is going to move about 0.49″ at 100 yards, nearly doubling your group size. With a 105gr VLD, the bullet moves 0.28″ … not as much to be sure, but still enough to ruin a nice small group. What about an AR15, shooting 55-grainers at 3300 fps? Well, if you miss that same 5 mph shift, your low-BC bullet moves 0.68″. That pushes a half-inch group well past an inch. If you had a half-MOA capable AR, now it’s shooting worse than 1 MOA. And, as you might expect, the wind effects at 200 and 300 yards are even more dramatic. If you miss a 5 mph, full-value wind change, your 300-yard group could easily expand by 2.5″ or more.

If you’ve already invested in an accurate rifle with a good barrel, you are “throwing away” accuracy if you shoot without wind flags. You can spend a ton of money on fancy shooting accessories (such as expensive front rests and spotting scopes) but, dollar for dollar, nothing will potentially improve your shooting as much as a good set of windflags, used religiously.

Windflags Sources and Options

Which Windflag to buy? There are many vendors selling windflags of various types, some with daisy wheels others without. You may want to go to a match and see what types works best for you.
