Getting the Most Out of Your Progressive Press — PowerUser Tips

Ultimate Reloader Progressive Press Hornady
Blue, Red, Green — There are many Progressive Press options on the market…

When you need ammo fast — lots of ammo, it’s hard to beat a progressive reloading press for output. We use progressive presses to load handgun ammo and .223 Rem cartridges for varmint safaris. With good dies, and proper press set-up, today’s progressive presses can produce surprisingly uniform and accurate ammo. No, you won’t see Benchrest Hall-of-Famers loading PPC cartridges on progressives. However, if you need 1000 rounds for your next prairie dog adventure, you should consider getting a progressive. Below you can see a Hornady Lock-N-Load AP configured to load .308 Winchester in bulk.

UltimateReloader.com has published helpful Tips to Optimize Progressive Rifle Loading. No matter whether you have a Red (Hornady), Green (RCBS), or Blue (Dillon) progressive, this article can help you load more efficiently and produce better results. Here are some highlights:

Proper Brass Prep
Just like a good paint job requires good prep work, great rifle ammo requires good brass prep. In order to make sure your rifle loading goes smoothly, make sure to perform the following brass prep steps:

  • Clean the brass (tumble, ultrasonic, etc.)
  • Inspect brass for cracks, deep dents, etc.
  • For military brass: de-prime, ream/swage primer pockets, size with small-base sizer die (small base usually optional).
  • Measure brass length — if too long, size and then trim.
  • Final inspection before loading.
  • Cleaning primer pockets may be something you’ll consider (I don’t clean primer pockets except for rare cases or match ammo).

Smooth and Steady Pace
Since you’re loading rifle ammunition on a progressive, you’re already saving a load of time, so there’s no need to rush things! Attention to detail is super-important for safety and for good results. Always keep an eye on powder level (goes down FAST) and what’s happening at each station.

The Right Press and Press Setup
Look for a heavy-duty, well-built press that will stand up to rifle loading. You’ll also want to make sure your powder measure will have the proper capacity (~25 grains for .223, ~50 grains for 308). If you are bulk reloading, ensure you have enough stations for sizing, charging, powder check, bullet feed, bullet seating, and (optional) bullet crimp. Compare the powder measuring systems, and give careful consideration to the priming process. You want case priming to be 100% reliable. This video reviews the differences between the Dillon XL-650 and the new XL-750 Progressive presses.

Dollars and $ense — Bargain 9mm Ammo Vs. Handloading

Sig Sauer P210 Legend

Everyone should have a 9mm Luger (9x19mm) pistol. The 9mm Luger round feeds/cycles great, recoil is moderate, and a vast array of excellent 9mm handguns are available. And, perhaps most importantly, quality factory ammo is affordable. In fact because 9x19mm ammo is produced in such quantity, it is some of the cheapest centerfire pistol ammo you can buy. Today we’ve found some great 9mm Luger ammo deals for you, with big-name factory stuff for under 18 cents per round.

At that price, it may not be worth reloading. Consider this — typical 9mm component costs easily approach fifteen cents per round even with free brass: Bullet ($0.08 – $0.10), Powder ($0.02), and Primer ($0.04). Given the costs of bullets, powder, and primers, it may not be worth reloading 9mm Luger, especially if you value your precious time!

Should You Reload 9mm Ammo? Run the Numbers, Then Decide…
While this Editor reloads almost all his .45 ACP and .44 Magnum ammo, I generally shoot factory ammo in my 9mm Luger pistols. Why? When you give some reasonable value to the time you spend setting-up and operating your reloading press, it is hard to beat factory ammo at around $10 per 50-count box (i.e. $0.20/round). While once-fired 9mm brass is plentiful (and cheap), you can easily spend 15-16 cents per round just on bullet, powder, and primer. So reloading may only save you 4 or 5 cents per round. Hence if you load 200 rounds per hour (including set-up time), you only recoup $8 to $10 per hour (at best) for all your effort. You may decide, as I did, that my time was worth more than that.

Loading with Arbor Press and Hand Dies — Here’s How to Do It

arbor press hand die

Creedmoor Sports has released a series of helpful “how-to” videos in its new InfoZone web page. In the latest InfoZone video Bill Gravatt shows how to seat bullets using L.E. Wilson Hand Dies and an Arbor Press. The basic process is simple, particularly with a micrometer-top seating die. That makes it easy to adjust and set seating depth. Before you start seating bullets, you want to adjust the height of the arbor so the stroke is appropriate to the height of your die.

Bill Gravatt Shows How to Use Hand Seating Dies — Creedmoor INFOZONE

ARBOR PRESS TECHNIQUE: When using an arbor press, smooth is good. You don’t want to slam the handle down quickly. Try to repeat the same motion each time. You can also experiment by seating the bullet part way, then rotate the cartridge (in the die) and do the final seating with a second stroke. If your arbor press has a force gauge, note both the max value of the gauge needle and how it moves as you seat the bullet. If the needle spikes too rapidly, or bounces back and forth irregularly, set that cartridge aside and/or mark it. You could have neck tension issue with that case or some other fault. You might even have a bad bullet. That’s rare, but can happen. The key to success is moving the press arm in a smooth motion every time, maintaining the same down-pressure with each cartridge.

Here Bill Gravatt Offers a Simple Tip for Adjusting Wilson Seating Dies

One of our Forum readers asked “How can I get a custom in-line seater for my new rifle?”. First, we would say that, if you are not shooting an unusual Wildcat, check first to see if L.E. Wilson makes a stainless Micrometer Seater Die for your rifle. These dies are a joy to use, and we’ve found the fit to be exceptionally good with many calibers. Typically priced from $90-$100, Wilson stainless micrometer-top seaters are available for dozens of cartridge types: .204 Ruger, 20 BR, .222 Rem, .223 Rem, 22 PPC, 22 BR, .22-250, .223 WSSM, 6 PPC, 6mmBR, 6XC, 243 Win, .243 WSSM, 25 WSSM, 6.5×47 Lapua, 6.5 Creedmoor, 6.5-284, 26 Nosler, .270 WSM, 7mm-08, .284 Win, 28 Nosler, 7mm RUM, 30 BR, 30 IHMSA, .308 Win, .300 WinMag, .338 Edge (and MORE).

If you do want a custom seater die, the process is relatively simple. Purchase a die blank from Wilson and have your gunsmith run the chambering reamer in. Forum member Gunamonth explains: “I start with a Wilson seating die blank. They’re available from Sinclair and other vendors. Just run the reamer in. For some of my rifles, where I wanted the stainless die with the micrometer adjustment, I bought a smaller die and had the smith ream it with the chamber reamer. That’s how I had my 6 Dasher and 6mm AI seaters made. With the Dasher I stared with a 6mmBR Micrometer die.”

Wilson inline seater die and blank

SEATER STEM TIP: If, on your seated bullets, you are seeing a sharp line around the jacket near the ogive, you may want to smooth out the leading edge of the Wilson seater stem (see above left). Do this by putting a little lapping compound on one bullet and manually spin this around in the stem. Without much effort you’ll have a smooth bullet/stem interface.

Micrometer Top Add-on
We really like micrometer tops on a seating die. But what if Wilson doesn’t make a micrometer top seater for your chambering? Don’t despair, Sinclair Int’l sells a $39.99 micrometer top that can be added to Wilson standard seaters or to a custom seater die made from a Wilson die blank.

TEN Worst Reloading Mistakes — Do You Agree with This List?

Shooting Times Reloading Failures Mistakes Top Ten 10

Last fall, Shooting Times released an article entitled “Ten Most Common Reloading Mistakes”. Listed below are the Top Ten mistakes hand-loaders can make, at least according to Shooting Times. What do you think of this list — does it overlook some important items?

Top Ten Reloading Mistakes According to Shooting Times:

1. Cracked Cases — Reloaders need to inspect brass and cull cases with cracks.

2. Dented Cases — Dents or divets can be caused by excess case lube.

3. Excessive Powder Charge — Overcharges (even with the correct powder) can be very dangerous.

4. Primers Not Seated Deep Enough — “High” primers can cause functioning issues.

5. Crushed Primers — Some priming devices can deform primers when seating.

6. Excess Brass Length — Over time, cases stretch. Cases need to be trimmed and sized.

7. Bullets Seated Too Far Out — If the bullet is seated too long you may not even be able to chamber the round. Also, with hunting rounds, bullets should not engage the rifling.

8. Burrs on Case Mouths — Ragged edges on case mouths can actually shave bullet jackets.

9. Excess Crimp — This is a common problem with pistol rounds loaded on progressives. If case lengths are not uniform some cases will get too much crimp, others too little.

10. Inadequate Crimp — This can be an issue with magnum pistol cartridges in revolvers.

Do you agree with this list? We think some important things are missing, such as not adjusting full-length sizing dies properly. This can cause the shoulder to be pushed back too far (or not far enough). Another common mistake is using brass that is worn out, i.e. stretched in the case-head area from multiple cycles of hot loads. We also think the #1 error a reloader can make is using the wrong powder altogether. That can be a fatal mistake. See what happens when you load pistol powder in a rifle.

It’s 2020! Welcome the new year and a new decade. We know many of our readers will be spending the winter day indoors. If you need a break from the bowl games on TV, here are eight interesting and informative videos that are worth watching. The subject matter runs the gamut from benchrest gunsmithing to long-range varmint silhouette competition. There are also reviews of some of the best precision rifle options for PRS and NRL22 disciplines. Enjoy our New Year 2020 Video Fest.

1. UltimateReloader — 14 Reloading Presses Compared

Epic Reloading Hardware Test — 14 Single-Stage Presses. In this remarkable video, Gavin Gear of UltimateReloader.com reviews fourteen (14) single-stage reloading presses. This is the most comprehensive reloading press comparison test ever done by anyone, anywhere. The presses range from compact units to large-frame exotics from Europe. If you are in the market for a single-stage press in 2020 this is a MUST-watch video. Brands include Forster, Hornady, Lyman, MEC, RCBS, Redding, Turban (Prazipress).

2. Precision Riflesmith — Profile of Benchrest Smith Mike Bryant

Texas gunsmith Mike Bryant is a talented benchrest shooter and a highly respected builder of competition and hunting rifles. In this wide-ranging interview, Mike talks about benchrest competition, the key factors that contribute to rifle accuracy, and about his career as a gunsmith.

3. Erik Cortina — Mag-Feed Testing Borden Action with 6BR


Click the Speaker Icon (lower right) to HEAR AUDIO

Our friend Erik Cortina has built a new PRS/NRL rifle based on the new Borden Super Short 6 Action. This video show Erik’s first mag-feeding test with ten 6BR loaded rounds. You’ll see there is NO problem speed-feeding the short 6BR case. Erik tells us: “I removed the firing pin from bolt for safety. The magazine has not been modified in any way. I would say there is no need to do anything to it, she’s ready to run!” Impressive indeed.

4. Shooting USA — Texas Varmint Benchrest Match

Varmint Benchrest silhouette TexasThis episode of Shooting USA TV features long-range varmint silhouette competition in Texas. This discipline combine the pure accuracy of benchrest competition with the fun of knocking down critter targets. These are smaller than standard silhouettes, so it’s quite a challenge to hit them at 300 yards and beyond.

In this episode, host John Scoutten competes with his 6.5 Creedmoor PRS rifle. Most shooters use benchrest-grade rifles with premium front rests. NOTE: This video shows some top-flight benchrest rifles, and also covers the origins of benchrest varmint silhouette in Pennsylvania. There are even some AccurateShooter Forum members on screen.

5. Vickers Tactical — .308 Win Bolt Gun Vs. .308 Win Gas Gun

This interesting video from Vickers tactical compares and contrasts two tactical style rifles both chambered for the .308 Winchester. The test team compares functionality, accuracy, ergonomics, and versatility. Each platform has its advantages, as the video reveals.

6. Outdoor Life — The Best New Affordable Precision Rifles

This video showcases three modern tactical-style rifles suitable for the PRS Production (Factory) Class which is limited to $2000 for rifle alone, not counting optics (Rule 2.3.1). Outdoor Life Shooting Editor John Snow puts three capable rifles through their paces: Patriot Valley Arms John Hancock, BadRock Precision SouthFork, and Seekins Precision Havoc Bravo.

7. Aerial View of Deep Creek Shooting Range in Montana

The Deep Creek Range near Missoula, Montana, is one of the best 1000-yard ranges in the country. Many long-range benchrest records have been set in this scenic, tree-lined facility. Now, thanks to Forum member David Gosnell (aka “Zilla”), you can see Deep Creek from the air. David flew a camera drone over the Deep Creek Range, soaring from firing line to the target bay and back again. This video gives you a “birds-eye view” of one of America’s elite ranges.

8. Nat’l Rifle League — Intro to NRL22 Rimfire Tactical Matches

NRL22 is a great way to get into competition shooting with minimal expense. There are Five (5) classes: Open, Base, Ladies, Young Guns (8-16), and Air Rifle. Base Class is for the budget-minded shooter — the combined MSRP of Rifle and Optic may not exceed $1050.00 (so you could spend $550 on a rifle and $500 on a scope for example). That keeps the sport affordable. Open, Youth, and Ladies Classes have no price limits on Rifle and Optic. Visit NRL22.org to find an NRL22 match near you.

Great Range Transport Case Made from Horse Grooming Box

Range carry loading reloader box case transport horse equine grooming case box

Folks who load at the range need to bring a lot of gear — reloading presses, powder dispensers, scales, funnels, sizing/seating dies, brass prep tools and more. And there may be other important items to transport — such as ammo caddies, LabRadar mounts, over-size rest feet, and even barrel fans.

A rifle case works fine for carrying your scoped rifle, but you still need to organize all your reloading tools and other gear, and transport them safely from home to range and back again. Some guys have built their own loading tool-boxes from wood. Other may stuff gear in a couple of plastic range boxes. But clever Chris Covell came up with an even better solution.

Chris sourced a handsome, sturdy metal Horse Grooming Box from eBay. Chris reports the multi-feature metal box “works perfectly for reloading. My ChargeMaster is now out of the wind.”

On top, below the hinged metal lid, is a large compartment that holds Covell’s funnels, scales, priming tool, trickler and other vital gear (photo on right). This top compartment is deep enough to handle wide-mouth funnels with no problem.

Slide-Out Drawer with Dividers
Below the top level is a handy sliding drawer with multiple dividers. This is perfect for holding Covell’s inline seating dies, case-neck deburring and chamfering tools, among many other smaller bits and pieces.

How to Clean Cartridge Brass with Ultrasonic Cleaning Machines

Ultrasonic Cleaning RCBS Ultrasound .308 Winchester 7.62x51 brass casings

Tumblers and walnut/corncob media are old school. These days many shooters prefer processing brass rapidly with an ultrasonic cleaning machine. When used with the proper solution, a good ultrasonic cleaning machine can quickly remove remove dust, carbon, oil, and powder residue from your cartridge brass. The ultrasonic process will clean the inside of the cases, and even the primer pockets. Tumbling works well too, but for really dirty brass, ultrasonic cleaning may be a wise choice.

READ FULL UltimateReloader.com Article on Ultrasonic Case Cleaning.

Our friend Gavin Gear recently put an RCBS Ultrasonic cleaning machine through its paces using RCBS Ultrasonic Case Cleaning Solution (RCBS #87058). To provide a real challenge, Gavin used some very dull and greasy milsurp brass: “I bought a huge lot of military once-fired 7.52x51mm brass (fired in a machine gun) that I’ve been slowly prepping for my DPMS LR-308B AR-10 style rifle. Some of this brass was fully prepped (sized/de-primed, trimmed, case mouths chamfered, primer pockets reamed) but it was gunked up with lube and looking dingy.”

UltimateReloader.com Case Cleaning Video (7.5 minutes):

Gavin describes the cleaning exercise step-by-step on UltimateReloader.com. Read Gavin’s Cartridge Cleaning Article to learn how he mixed the solution, activated the heater, and cycled the machine for 30 minutes. As you can see in the video above, the results were impressive. If you have never cleaned brass with ultrasound before, you should definitely watch Gavin’s 7.5-minute video — it provides many useful tips and shows the cleaning operation in progress from start to finish.

Ultra Dry Necks After Ultrasonic Cleaning — Some Suggestions

The Ultrasonic cleaning process gets cartridge brass so “squeaky clean” that increased force may be required to seat your bullets, or they may “grab” as they go in the necks. To reduce bullet-seating effort, you may benefit from adding a little dry case lube inside the case-neck before loading (use a nylon brush). Another trick is adding a teaspoon of Ballistol lube to the cleaning solution. That provides a trace lubricant inside the necks, but does not interfere with powder ignition in any way.


The latest Gen2 RCBS ultrasonic cleaning machine has a large 6.3-quart capacity. That’s nearly 100 percent larger than the first generation machine in Gavin’s video. The Gen2 machine, $322.02 on Amazon, features a second ceramic heater and transducer to better clean brass cases and firearm parts. The LED is easily programmable, and the timer can be set for up to 30 minutes of cleaning. The original 3.2 quart capacity RCBS ultrasonic machine, as shown in Gavin’s video, is still available for $166.56 at Midsouth Shooters.

Case-Neck Chamfer Tools — Choosing the Right Option

Neck case chamfer tools Redding Forster Rocket model 15-p
Shown is the Redding Model 15-P Competition Piloted Inside Chamfering Tool with pilot rod that centers in the case flash hole. Also shown is a Forster 45° Rocket Tool.

There are a wide variety of reloading tools designed to cut a slight chamfer in case necks and deburr the edge of the case mouth. You don’t need to spend a lot of money for an effective tool. A basic “rocket-style” 45° chamfering tool, such as the Forster, actually does a pretty good job taking the sharp edge off case mouths, particularly if you use a little scotch-pad (or steel wool) to smooth the edge of the cut. The Forster chamfer tool, shown below, is a nicely-made product, with sharper cutting blades than you’ll find on most other 45° chamferers. It costs $20.99 at Brownells.com.

forster rocket 45 degree neck chamferer chamfer tool

Redding sells a handy piloted chamfering tool with a 15° inside cutting angle and removable accessory handle. This Redding Model 15-P chamferer works really well, so long as you have consistent case OALs. The pilot rod (which indexes in the flash hole) is adjustable for different cartridge types (from very short to very long). This ensures the concentricity of the inside neck chamfer to the case mouth. This quality tool ($35.99 at Brownells) works with cases from .22 to .45 Caliber.

Neck case chamfer tools Redding Forster Rocket model 15-p

Sinclair International offers a 28° carbide chamferer with many handy features (and sharp blades). The $29.99 Sinclair Carbide VLD Case Mouth Chamfering Tool will chamfer cases from .14 through .45 caliber. This tool features a removable 28° carbide cutter mounted in the green plastic Sinclair handle. It is on sale right now for $24.99 at Brownells. NOTE: A hex-shaft cutter head power adapter can be purchased separately for $14.99 (Sinclair item 749-002-488WS). This can be chucked in a power screwdriver or used with the Sinclair Case Prep Power Center.

Neck inside chamfer chamferer case neck tool

Many folks feel they can get smoother bullet seating by using a tool that cuts at a steeper angle. We like the 22° cutter sold by Lyman. It has a comfortable handle, and costs just $11.54 at Midsouth Shooters. The Lyman tool is an excellent value, though we’ve seen examples that needed sharpening even when new. Blade-sharpening is easily done, however.

K&M makes a depth-adjustable, inside-neck chamferer (“Controlled Depth Tapered Reaper”) with ultra-sharp cutting flutes. The latest version, which costs $51.70 at KMShooting.com, features a central pin that indexes via the flash hole to keep the cutter centered. In addition, the tool has a newly-designed handle, improved depth-stop fingers, plus a new set-screw adjustment for precise cutter depth control. We caution, even with all the depth-control features, if you are not careful, it is easy to over-cut, slicing away too much brass and basically ruining your neck. We think that most reloaders will get better results using a more conventional chamfer tool, such as the Forster or Redding 15-P.

K & M K&M neck chamferer reamer controlled depth

One last thing to note — tools like the K&M and the Sinclair chamferer are often described as VLD chamferers. That is really a misnomer, as bullets with long boat-tails actually seat easily with very minimal chamfering. In reality, these high-angle chamferers may be most valuable when preparing brass for flat-base bullets and bullets with pressure rings. Using a 22° or 28° chamferer can reduce the risk of cutting a jacket when using VLD bullets though — so long as you make a smooth cut.

Case-Head Separation — How to Detect Potential Problems

cartridge case separation

We are re-publishing this article at the request of Forum members who found the information very valuable. If you haven’t read this Safety Tip before, take a moment to learn how you can inspect your fired brass to determine if there may be a potential for case separation. A case separation can be dangerous, potentially causing serious injury.

cartridge case separationOn the respected Riflemans’ Journal blog there was an excellent article about Cartridge Case-Head Separation. In this important article, Journal Editor GS Arizona examined the causes of this serious problem and explained the ways you can inspect your brass to minimize the risk of a case-head separation. As cases get fired multiple times and then resized during reloading, the cases can stretch. Typically, there is a point in the lower section of the case where the case-walls thin out. This is your “danger zone” and you need to watch for tell-tale signs of weakening.

The photo below shows a case sectioned so that you can see where the case wall becomes thinner near the web. You can see a little arrow into the soot inside the case pointing to the thinned area. This case hadn’t split yet, but it most likely would do so after one or two more firings.

cartridge case separation

Paper Clip Hack for Detecting Problems
The article provided a great, easy tip for detecting potential problems. You can use a bent paper clip to detect potential case wall problems. Slide the paper clip inside your case to check for thin spots. GS Arizona explains: “This simple little tool (bent paper clip) will let you check the inside of cases before you reload them. The thin spot will be immediately apparent as you run the clip up the inside of the case. If you’re seeing a shiny line on the outside and the clip is really hitting a thin spot inside, it’s time to retire the case. If you do this every time you reload, on at least 15% of your cases, you’ll develop a good feel for what the thin spot feels like and how it gets worse as the case is reloaded more times. And if you’re loading the night before a match and feel pressured for time — don’t skip this step!”

AMP Annealing — R&D, Innovation, and Cutting-Edge Technology

AMP Annealing Made Perfect science under microscope technology

When Annealing Made Perfect (AMP), a New Zealand-based company, first unveiled its original induction annealing machine at SHOT Show 2015, it was big news in the reloading world. This was a real breakthrough — an induction annealer running on electricity that was fully programmable. No more flames to fuss with. The advent of the AMP annealer was a true “game-changer” for the shooting enthusiasts who reloaded their ammo.

The AMP system is based on smart science and modern technology. Right from the start, AMP invested in advanced lab equipment (such as gear for Micro-Vickers hardness testing). AMP also worked with independent outside metallurgical laboratories. And AMP invited shooters from around the world to send in sample cartridge cases. AMP accumulated a huge archive of cartridges from .17 Hornet to an array of .50 BMG wildcats and everything in-between. AMP’s archive includes multiple brands and even different lot numbers of the same cartridge. AMP now offers the most highly developed and precise consumer annealing system on the planet. That is because of the amazing amount of R&D behind the product, plus the use of advanced technologies.

Annealing Under the Microscope — Informative Articles

Alex and Matt Findlay have produced a series of articles called “Annealing Under the Microscope”. The first of these was released in July 2017. Part 1 was a general explanation of annealing, and busted a number of myths. It examined the repeatability of annealing over multiple reloads, and conducted a series of tensile bullet pull tests.

FULL ARTICLE LINK: Annealing Under the Microscope, Part One

Annealing Different Brands of Brass
Part 2 of Annealing Under the Microscope covered an important topic — annealing for different brands of brass. This article examines the reasons why different brands of the same cartridge can require different annealing settings. The article also reveals that lot to lot variations of the same brand of brass can make a big difference.

AZTEC Annealing System — AMP Annealers become Smart Machines
In late 2017, Alex and Matt started the development of their revolutionary AZTEC system, which in effect transformed AMP annealers into SMART annealers. It meant that individual customers could analyse their own cases with laboratory grade accuracy without the need to send samples to the AMP lab for calibration.

Part 3 of Annealing Under the Microscope was released in July 2018 after nearly 12 months of R&D on AZTEC. It focused on how to best utilize this new self-calibration capability. It also highlighted the difference between several “premium” brands of brass compared to cheaper alternatives.

Benefits of Precision Annealing — Accuracy and Repeatability
Part 4 of the series was released in September 2019. It focused on the true benefits of accurate annealing, and the arguments for annealing every reload. The study identified sizing accuracy and repeatability as the key factor. This article also revealed the first prototype of AMP’s new auto bullet seater with seating pressure data capture.

Proof on the Target — Down-Range Benefits of Annealing
In Part 5 of the series, AMP’s experts focus on the real world, down-range benefits of annealing, turned out to be a much more complex process than AMP initially planned. Accordingly, Part 5 was conducted in three stages, with three detailed write-ups.

AMP Annealing Made Perfect science under microscope technology

The Part 5, Stage 1 paper examined sizing accuracy of annealed vs un-annealed cases, taking two sets of three identical Peterson Cartridge .308 Winchester cases through twenty (20) reloading cycles. For every cycle, cases were measured both fire-formed and as re-sized. With each cycle the cases were measured for case length, shoulder bump, neck OD, and head OD.

Field Testing in Tennessee — Proof on Target
The Part 5, Stage 2 article covered detailed ballistic testing using multiple rifles, cartridges, and shooters at the Strategic Edge range in Tennessee.

AMP Annealing Made Perfect science under microscope technology

The Tennessee testing sessions accumulated a wealth of data on velocity spreads and group sizes right out to 1,000 yards. The evidence showed a clear advantage for annealed brass, both for average group size and average Extreme Spread for the groups shot with AMP-annealed cases.
