Intelli-Dropper Priced Under $200.00: The new Frankford Arsenal Intelli-Dropper will be available very soon from leading vendors such as Midsouth, Grafs.com, and MidwayUSA for around $199.99.
A new electronic powder scale/dispenser just hit the market to compete with units from Lyman, RCBS, and Hornady. The new Frankford Arsenal Platinum Series “Intelli-Dropper” scale/dispenser looks similar to a ChargeMaster Lite, with a LED digital touch-screen. But it is a true “new generation” device with an advanced brain that can “talk” to a Mobile App on your smartphone via BlueTooth. This way you can store powder and load information on your smartphone and then control the scale/dispenser from the App. Advantages? You could list different loads for different bullets, and you can also keep a complete history of your loading for different cartridges. For years this Editor recorded his load data via a spreadsheet on a laptop computer. Now you can have the equivalent of a loading spreadsheet right in your phone.
| Frankford Arsenal Platinum Series Intelli-Dropper FEATURES |
Large Back-lit LCD Display
Auto and Manual Trickle capability
Holds up to 7,000 grains (1 lb) of powder |
Bluetooth Capability
Downloadable App Functionality
App Has Powder and Bullet Databases |
Manual Trickle Capability — Nice!
Another cool feature is that you can use the machine to manual trickle. So you could throw powder rapidly with a manual powder measure then “trickle up” to the final tenth of a grain.
 Intelli-Dropper Controls
The Frankford Arsenal Platinum Series Electronic Intelli-Dropper features an individual powder calibration button for the fastest, most accurate powder measurements. The large back-lit LCD display provides easy-to-see controls. The machine stores load data in your downloadable smart-phone or tablet App. The Intelli-Dropper features BOTH Auto and Manual trickle capability with up to 200 grains of powder per throw. Holds up to 7,000 grains (1 lb) of powder and offers +/- 0.1 grain accuracy.
Mobile App Features
The Intelli-Dropper’s downloadable App features bullet and powder databases, with the ability to add additional bullets/powders. The App stores your load data, and comes with info already stored in the App including cartridge list, powder list. Plus the bullet list is very detailed with bullet type, caliber, weight, ballistic coefficient, sectional density, and length. The App lets you input charge weight, case, primer type, barrel length and more. And the App can even upload photos of your test targets — so you can record group size accuracy results. That’s cool.

The way you drop powder in the case will affect your max powder volume and the load density. Look at the photo above. These photos show the SAME 30.6 grains of powder using four different fill methods. If you are working with a powder that is below max safe pressure at your current “full case” (with room left for the bullet), and you want to get more velocity with that powder, consider a different case-filling technique.
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:

While many of our readers are caught in the wicked cold-spell hitting the North Central states, take heart — spring is right around the corner. That means folks will be getting ready for varmint safaris. Here’s a story that may help you choose a cartridge for your next varmint rifle.
For many years, Ken Lunde journeyed to South Dakota to visit with his father, and do a little varmint hunting. This article features Ken’s Cooper Model 21 Montana Varminter chambered in .204 Ruger. During past varminting holidays in South Dakota, Ken had a chance to try the speedy .204 against his “old reliable” .223. He came to favor the .204 for its accuracy, flat trajectory, and superior performance in the wind. Ken told us: “I love my .223, but the .204 has the edge for Dog-Town duty.”
The Cooper Montana Varminter in .204 Ruger
by Ken Lunde

I’ve been a big fan of Cooper Arms rifles ever since my dad introduced them to me a few years ago. I prefer Cooper Arms rifles over others because they perform as they should out-of-the-box, and have outstanding workmanship and beauty. You get form and function. You don’t need to choose one over the other. For the price one pays, Cooper Arms rifles are a great bargain. I mount a quality scope, usually a higher-end Leupold with a 40mm objective, go through barrel break-in, and they always perform extraordinarily well. I should state that all of my rifle shooting is geared towards hunting. In other words, any shooting I do on paper is treated as preparation for using the same rifle for hunting, whether it’s for varmints such as prairie dogs, or for larger game.
Cooper Varmint Rifles–Components and Variations
The featured rifle is a Cooper Arms M21 Montana Varminter (aka “MTV”) chambered in .204 Ruger. It has a 24″ varmint-taper stainless steel barrel with a 1 in 12-inch twist. This twist rate seems to be typical of .204 Ruger barrels from other manufacturers. The stock is AA+ grade Claro Walnut, and has the varmint fore-end, “Buick” vents, and steel grip cap that are standard on the Montana Varminter configuration. Among Cooper’s three wood-stocked varmint rifle configurations — Varminter, Montana Varminter, and Varmint Extreme — I prefer the Montana Varminter as it seems to be the best balance of value versus features. Plus, I like the “Buick” vents. They’re very pleasing, at least to my eyes. Maybe that’s why I own seven of them, in M21 and M22 actions, and in a variety of calibers. [Editor: Ken’s father has a near-identical .204 Ruger Cooper, with consecutive serial number.]
For this rifle, I decided to mount a Leupold VX-III 6.5-20×40 LR scope with the Varmint Hunter reticle. The rifle came with Leupold STD bases in Matte finish, and I used Leupold 30mm STD rings in Medium height and Matte finish. I took the time to align the bottom rings on the bases, and properly lapped them. Other than mounting the scope, no custom work was done, because none was necessary. The trigger is superb out-of-the-box, which is typical of Cooper rifles.
Load Development and Accuracy
 I first tried factory ammo, loaded with Hornady 32gr and 40gr V-Max. The 32gr load shot the best—five-shot groups were slightly larger than a half-inch at 100 yards. My dad heard that Alliant Reloder 10X was a good powder for this cartridge, and he worked up a load using the Sierra 32gr BlitzKing bullet. He found that 26.5 grains was the right amount for his rifle. Considering that my rifle was probably made on the same day, having a consecutive serial number, I decided to try my dad’s load, along with a half-grain up and down, meaning 26, 26.5, and 27 grains of powder. I, too, found that my rifle prefers 26.5 grains of RL 10X. With this load, I’ve been able to shoot consistent quarter-inch, five-shot groups at 100 yards. Cartridge OAL is 2.353″, or 1.990″ measured from the ogive.
I am using Winchester brass, Federal 205M primers, Alliant Reloder 10X powder, and Sierra 32gr BlitzKing bullets. I use Forster dies, and load with a Forster Co-Axial single-stage press. Here are two typical targets. As you can see, this .204 can shoot.

Cartridge Smack-Down — .204 Ruger vs. .223 Remington
Ken made these comments when he first tested his .204 Ruger vs. his trusty (and very accurate) .223 Remington: “I brought along two rifles. The first was my ‘proven’ varmint rifle, the one chambered in .223 Rem. It has stunning wood, and clearly escaped the factory with AAA grade Claro Walnut. That rifle also shoots consistent five-shot, quarter-inch groups at 100 yards. For the .223, my preferred load uses Winchester brass, Federal 205M primers, Hornady 40gr V-Max bullets (non-moly), and 26.2gr of Vihtavuori N133 powder.
I found that I very much enjoyed shooting the .204 Ruger rifle, which explains why I used only the .204 Ruger during the second trip, although I also brought along the .223. Why did I favor the .204? Well, those little 32gr bullets really zing out of the barrel, with a very flat trajectory, like a .22-250. And, to my surprise, they buck the wind very well, perhaps even better than .223. While I am no ballistics expert, I think that this may be due to its high velocity, clearly over 4,000 fps.”

Here are highlights from an article Glen Zediker wrote for the Midsouth Blog. In this article Glen focuses on cartridge brass for semi-auto rifles, AR-platform guns in particular. Glen notes that semi-autos are tougher on brass than bolt-action rifles, so you need strong, durable brass, that has been full-length sized. And you need to be careful about neck tension, and primers. The article starts with Glen’s recommendations for tough, hard brass, and then includes the points outlined below.
Glen is the author of many excellent books on reloading. This article is adapted from Glen’s books, Handloading For Competition and Top-Grade Ammo, available at Midsouth HERE. For more information about other books by Glen, visit ZedikerPublishing.com.
ONE: Full Length-Size Cases with Adequate Shoulder Set-Back
This is a huge source of debate… amongst my readers, but, since now I’m strictly speaking of semi-auto needs I doubt there will be much dissent: full-length resize all cases! Most cases from most semi-autos will emerge with a pretty well-blown case shoulder [taming down an excessively functioning gas system can reduce this]. Make double-sure you’re sizing the cases down to at least 0.003 clearance. If you don’t there are safety and function problems ahead.
TWO: USE Sufficient Neck Tension
The case neck [must be] reduced an adequate amount to retain the bullet. There should be a minimum net difference of 0.003 inches (three-thousandths) between sized outside case neck diameter and loaded round outside case neck diameter. [Editor — that means at least three thou of “grip”.] Reason: don’t take a chance of inadvertent bullet movement during the recoil and feeding cycles. That movement can be back or forward! It’s easily possible for a bullet to jump ahead when the inertia from the bolt carrier assembly chambers the next round.
THREE: Use Tough Primers
Choose a tough primer! There’s a floating firing pin on an AR15 (M1A also) that is supposed to be held in check but that system doesn’t always work! If you load and extract a round and see a little dimple in the primer, that’s from the firing pin tapping off of it (again, created by inertia of bolt closing). A combination of a high primer and a sensitive primer cup assembly can create a “slam-fire”. Brands? CCI has some mil-spec primers that work well, and I’ve had great success with Remington 7-1/2. Some of the well-respected “match” primers are a little thin. The CCI and Remington also hold up well to the (sometimes) greater firing forces working on the primer (again, from the quick unlocking).
Here’s what I use from Midsouth.
FOUR: Be Sure to Seat Primers Below Flush
And, finally, make double-sure that each and every primer is seated to below flush with the case head! That’s true for any firearm (because it also means that the primer is fully seated) but imperative for safety in a semi-auto. This is especially an issue for those who use a progressive-type loading press.

 Sinclair International has released an interesting article about Case Concentricity* and bullet “run-out”. This instructional article by Bob Kohl explains the reasons brass can exhibit poor concentricity, and why high bullet run-out can be detrimental to accuracy.
Concentricity, Bullet Alignment, and Accuracy by Bob Kohl
The purpose of loading your own ammo is to minimize all the variables that can affect accuracy and can be controlled with proper and conscientious handloading. Concentricity and bullet run-out are important when you’re loading for accuracy. Ideally, it’s important to strive to make each round the same as the one before it and the one after it. It’s a simple issue of uniformity.
The reason shooters work with tools and gauges to measure and control concentricity is simple: to make sure the bullet starts down the bore consistently in line with the bore. If the case isn’t properly concentric and the bullet isn’t properly aligned down the center of the bore, the bullet will enter the rifling inconsistently. While the bore might force the bullet to align itself with the bore (but normally it doesn’t), the bullet may be damaged or overstressed in the process – if it even it corrects itself in transit. These are issues we strive to remedy by handloading, to maintain the best standard possible for accurate ammunition.
The term “concentricity” is derived from “concentric circle”. In simple terms it’s the issue of having the outside of the cartridge in a concentric circle around the center. That goes from case head and center of the flash hole, to the tip of the bullet.
Factors Affecting Concentricity
The point of using this term is to identify a series of issues that affect accurate ammunition. Ideally this would work best with a straight-walled case; but since most rifle cartridge cases are tapered, it equates to the smallest cross section that can be measured point by point to verify the concentric circle around the center. For the examples below, I’m working with .308 Winchester ammo.
Figure 1: The cartridge.
Figure 2: Centerline axis of the case, extending from flash hole to case mouth.
The case walls have to be in perfect alignment with the center, or axis, of that case, even if it’s measured at a thousandth of an inch per segment (in a tapered case).
Figure 3: Case body in alignment with its axis, or centerline, even in a tapered case.
The case neck must also be in alignment with its axis. By not doing so you can have erratic bullet entry into the bore. The case neck wall itself should be as uniform as possible in alignment and in thickness (see the M80 7.62x51mm NATO cartridge in Figure 5) and brass can change its alignment and shape. It’s why we expand the case neck or while some folks ream the inside of the neck and then turn the outside for consistent thickness, which affects the tension on the bullet when seated.
Figure 4: Neck in alignment with center of the case axis.
Figure 5: Variations in case neck wall thickness, especially on some military brass, can cause an offset of the bullet in its alignment. This is an M80 ball round. Note the distinct difference of the neck walls.
Having a ball micrometer on hand helps, especially with military brass like 7.62x51mm in a semi-auto rifle, where there are limits as to how thin you want the neck walls to be. In the case of 7.62 ball brass you want to keep the wall to .0145″.
Figure 6: A ball micrometer like this RCBS tool (#100-010-268) can measure case neck thickness.
Turning the outside of the neck wall is important with .308 military cases regardless of whether you expand or ream the neck walls. There are several outside neck turning tools from Forster, Hornady, Sinclair, and others. I’ve been using classic Forster case trimming (#100-203-301) and neck turning (#749-012-890) tools for 40 years.
Bullet Run-Out
The cartridge, after being loaded, still needs to be in alignment with the center of the case axis. Figure 7 shows a bad example of this, a round of M80 ball. A tilted bullet is measured for what’s known as bullet “run-out”.
Figure 7: An M80 round with the bullet tilted and not aligned with the axis. This will be a flyer!
Run-out can be affected by several things: (1) improperly indexing your case while sizing, which includes not using the proper shell holder, especially while using a normal expander ball on the sizing die (it also can stretch the brass). (2) The head of a turret press can flex; and (3) improper or sloppy bullet seating. This is also relevant when it comes to using a progressive press when trying to load accuracy ammo.
Mid Tompkins came up with a simple solution for better bullet seating years ago. Seat your bullet half way into the case, back off the seater die and rotate the case 180 degrees before you finish seating the bullet. It cuts down on run-out problems, especially with military brass. You also want to gently ream the inside of the neck mouth to keep from having any brass mar the surface of the bullet jacket and make proper seating easier. A tilted bullet often means a flyer.
Figure 8: Proper alignment from the center of the case head to the tip of the bullet.
(NOTE: This links to a Web Archive version of older Sinclair Int’l article.)
*Actually some folks would say that if we are talking about things being off-center or out-of-round, we are actually talking about “eccentricity”. But the tools we use are called “Concentricity Gauges” and Concentricity is the term most commonly used when discussing this subject.

Ultimate Reloader’s Gavin Gear is working on the most comprehensive reloading press comparison video.
UltimateReloader.com is a leading website showcasing reloading hardware and methodologies. Ultimate Reloader’s founder, Gavin Gear, regularly tests the latest and greatest reloading gear, including presses, case prep centers, cleaning systems and more. Gavin, shown above, is currently hard at work on “the mother of all” reloading press comparisons. He has secured 14 single-stage presses and set them up in his workroom/studio. This will be the most comprehensive reloading press video ever created.
Last week, Gavin was working hard in SHOT Show 2019 in Las Vegas, finding new products, and interviewing some important folks in the shooting sports industry. Here are four videos Gavin released this week for his Ultimate Reloader YouTube Channel.
New Products from Ruger for 2019
Gavin says: “I’m a big fan of Ruger rifles, in fact my first rifle was a Ruger 10/22! Since then I’ve published a lot of stories covering the Ruger Precision Rifle, and other Ruger products. While at the SHOT show this year I visited the Ruger booth, and got the scoop on the latest rifle offerings from Ruger.” Below is also an Ultimate Reloader preview video of the Ruger American Rifle in 6.5 Creedmoor and “Go Wild Camo” livery.
Here are some interesting comments from Gavin’s YouTube viewers:
“It’s amazing how low price [Rugers are] while still being made in the USA. Great job Ruger!” — J. Allen
“I own the RPR in 6.5, 5.56 [.223 Rem], .22 rimfire. The rifles are cheap it’s the bi-pods, rings, optics that make you dig deep in the wallet.” — 2d Amendment
“I am really digging the Ruger American Go Wild Camo, what an absolutely beautiful gun[.] I had a friend … with the 22 inch barrel and is hitting solid MOA groups out to 200.” — F. Earnest
New Products from Lyman for 2019
Lyman Products rolled out three impressive new reloading presses last year. This included an 8-station turret press, a beefy O-frame press, and a versatile C-Frame compact press.
Following up on last year’s successful product launches, for 2019 Lyman is releasing some impressive new tools and gear, including a cool new case trimmer and a deluxe shooting mat. In this video, Gavin interviews Lyman engineer Spencer Karoll, who discusses Lyman’s new product offerings.
Interview with Hornady President Steve Hornady
Gavin reports: “One of the great things about going to the SHOT Show is the people you get to talk with. At last year’s SHOT Show, I met Steve Hornady and talked for a few minutes. This year I [wanted] to have a conversation with Steve on camera! Steve was game, so here it is– a discussion about Hornady’s history, Hornady’s business philosophy, and Steve’s thoughts on new products like the 300 PRC.”
.224 Valkyrie Status Report — Info from Federal
Since its debut just before SHOT Show last year, the new .224 Valkyrie cartridge has been a “hot topic” in the gun industry. In this video interview Gavin covers the .224 Valkyrie’s first year. This video reveals key facts, clarifies misconceptions, and explains how Federal Premium has worked with the shooting community to realize the full potential of this cartridge.

Don’t have time to neck-turn hundreds of cases? Don’t want to invest in your own annealer? Want to try a Dasher or 6 BRA but don’t like the hassle of fire-forming? Then give Darrell Jones at DJ’s Brass a call at 205-461-4680. He can handle all the difficult brass forming/brass restoration chores efficiently and affordably. And Darrell’s turn-around time is typically very fast.
Hydro-Forming News — .284 Shehane, 6 PPC, 6 BRA, 6 Dasher and More
NEW for 2019! Darrell also just got a custom hydro die for the .284 Shehane, a wildcat based on the .284 Winchester. This is a very popular option for F-Open Shooters. He is also doing a ton of fire-forming for the 100/200 benchrest crowd, hydro-forming 220 Russian into 6 PPC. And he tells us “Those guys in Montana are keeping me very busying hydro-forming the 6BR Ackley (6 BRA). NOTE: Darrell offers Free Annealing with hydro-forming services, which starts at $60 per 100 cases.
 With the price of premium brass topping $1.00 per case for popular match cartridges, it makes sense to consider annealing your brass to extend its useful life. You don’t want to chuck out brass that costs a buck a case (or more)! Forum member Darrell Jones offers a full range of brass prep, brass forming, and brass restoration (annealing, ultra-sonic cleaning) at very affordable prices. Starting at just $20 per 100 cases ($25/100 for magnum cases), Darrell’s company, DJ’s Brass, will anneal your used brass using the impressive Bench-Source annealing machines.

The U.S. Army Marksmanship Unit publishes reloading “how-to” articles on the USAMU Facebook page. One Wednesday “Handloading Hump Day” post covered preparation of once-fired 5.56x45mm brass. This article, the first in a 3-part series, has many useful tips. If you shoot a rifle chambered in .223 Rem or 5.56x45mm, this article is worth reading. And visit the USAMU Facebook page for other hand-loading tips.
This week, Handloading Hump-Day will answer a special request from several competitive shooters in Alaska. They asked about procedures for morphing once-fired GI 5.56mm brass into accurate match brass for NRA High Power Rifle use. The USAMU has used virgin Lake City (LC) 5.56 brass to win National Championships and set National Records for many years. In this 3-part series, we’ll share techniques proven to wring match-winning accuracy from combat-grade brass.
Preparing Once-Fired GI 5.56 Brass for Reloading (Part 1 of 3)
Assuming our readers will be getting brass once-fired as received from surplus dealers, the following steps can help process the low-cost raw material into reliably accurate components.
1. Clean the Brass
First, clean the brass of any dirt/mud/debris, if applicable. Depending on the brass’s condition, washing it in a soap solution followed by a thorough rinsing may help. [This step also extends the life of the tumbling media.] Approaches range from low-tech, using gallon jugs 1/2 full of water/dish soap plus brass and shaking vigorously, to more high-tech, expensive and time-consuming methods.
2. Wet-Tumbling Options (Be Sure to Dry the Brass)
When applying the final cleaning/polish, some use tumblers with liquid cleaning media and stainless steel pins for a brilliant shine inside and out, while others take the traditional vibratory tumbler/ground media approach. Degree of case shine is purely personal preference, but the key issue is simple cleanliness to avoid scratching ones’ dies.
Shown below are Lake City cases after cleaning with Stainless Media (STM). Note: STM Case cleaning was done by a third party, not the USAMU, which does not endorse any particular cleaning method.
If a liquid cleaner is used, be SURE to dry the cases thoroughly to preclude corrosion inside. One method is to dump the wet brass into an old pillow case, then tilt it left/right so the cases re-orient themselves while shifting from corner to corner. Several repetitions, pausing at each corner until water stops draining, will remove most water. They can then be left to air-dry on a towel, or can be dried in a warm (150° F-200° F max) oven for a few minutes to speed evaporation.
3. Inspect Every Case
Once dry, inspect each case for significant deformation (i.e., someone stepped on it), damaged mouths/necks and case head/rim damage. Some rifles’ ejectors actually dig small chunks of brass out of the case head — obviously, not ideal for precision shooting. Similarly, some extractors can bend the case rims so badly that distortion is visible when spinning them in one’s fingers. These can be used for plinking, but our match brass should have straight, undamaged rims.
Dented case mouths are common, and these can easily be rounded using a conical, tapered tool, [such as a .223 expander mandrel. A dummy 7.62 or .30-06 cartridge with a FMJ spitzer can also work.] If most of your brass is of one headstamp, this is a good time to cull out any odd cases.
4. Check the Primers Before Decapping
Your clean, dry and inspected brass is now ready for full-length sizing, decapping and re-priming. Historically, primer crimps on GI brass have caused some head-scratching (and vile language) among handloaders. Our next installment will detail efficient, easy and practical methods to remove primer crimp, plus other useful handloading tips. Until next week, Good Shooting!
NOTE: The USAMU Handloading (HL) Shop does not RE-load fired 5.56 brass. We use virgin LC brass with our chosen primer already staked in place. However, our staff has extensive personal experience reloading GI brass for competition, which will supplement the Shop’s customary steps. In handloading, as in life, there are many ways to accomplish any given task. Our suggestions are note presented as the “only way,” by any means. Time for loading/practicing is always at a premium. Readers who have more efficient, alternative methods that maintain top accuracy are invited to share them here.
