Each Wednesday, the U.S. Army Marksmanship Unit publishes a reloading “how-to” article on the USAMU Facebook page. Yesterday’s “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 next Wednesday for the next installment.
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.
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.
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.
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.

For a few years now, Lyman has offered the Case Prep Xpress, an all-in-one case prep center that chamfers necks (inside and out), cleans and uniforms primer pockets, brushes the inside of case-necks, and uniforms flash holes. The unit can also ream out the crimps on military brass. However, the Lyman Case Prep Xpress does NOT trim cases.
The Lyman Case Press Xpress comes with all the necessary tools and attachments (listed below), so you don’t have to purchase extra accessories. The 5 gear-driven heads on the unit are powered by a high torque, low-speed motor ideal for case prep operations. Lyman’s Case Prep Xpress features handy storage areas for accessories, a removable brass shavings dump pan, and a handy clean-up brush.
Lyman Case Prep Xpress Includes:
Inside Deburr (VLD) Tool
Outside Deburr Tool
Flash Hole Uniformer
Primer Pocket Uniformer (Large & Small)
Primer Pocket Reamer (Large & Small)
Primer Pocket Cleaner (Large & Small)
Case Neck Brushes (25, 30, 38 & 45 Cal)
Case Neck Lube (Mica)
Removable Brass Shavings Dump Pan
In the two years that this product has been on the market it has been a hot seller. We’ve used the Case Prep Xpress. If you’re prepping hundreds of cases, this unit will save considerable time and reduce hand/finger fatigue. While the Case Prep Express is not as sturdy as the metal-bodied Hornady prep center, the Lyman unit offers a lot of functionality for the price ($108-$125 at various vendors).
Video clearly illustrates all case prep functions. Worth watching.
You can find Lyman’s Case Prep Xpress for under $120.00, making it much less expensive than the larger Hornady Case Prep Center, which runs about $400.00. The Hornady unit is beefier, and will trim cases. However, we think the compact Lyman unit makes sense for guys who already have a good case trimmer, such as a Forster or Wilson. The Lyman Case Prep Xpress is hundreds of dollars less than the Hornady prep center. The money you save will buy lots of bullets and brass.
Case Prep Xpress $108.08 at Midsouth
The Lyman Case Prep Xpress is sold by most of the big vendors. The best current price we found was at Midsouth Shooters Supply, which sells the Lyman unit for $108.08.

California shooter Mark LaFevers has come up with a slick, adjustable fixture that delivers a precise, repeatable inside-neck chamfer every time. He uses a Holland Case Mouth Chamfer Tool with a 14° cutter, but this set-up works equally well with other chamferers with an extended handle. With Mark’s tool jig, the Holland Tool inserts through the top, indexing vertically off a shoulder. A small recess is cut in the center of the wood base for the case head. The tool mount can be raised or lowered with the adjusting bolts on all four corners. Simply slide a trimmed-to-length case in the middle, give the Holland Tool a few spins, and you get a perfect, identical chamfer every time. Now that’s ingenuity! Mark isn’t planning to produce these commercially, but he’s happy if someone wants to copy his jig design.
NOTE: In the photos above, you see an older version of the tool. Hollands has improved the design of its current 14° Chamfer Tool. The cutting head now has a 3-flute design that provides a smoother, chatterless cut. The head is now made of carbide so it cuts faster and holds its cutting edge longer. This tool is available from Holland’s Shooters Supplies for $32.00 (item CMCT-CAR).

Folks have asked if there is a tool that can remove obstructions from a Lapua small, BR-sized flash hole without opening the hole size. The Lapua PPC/BR flash hole is spec’d at 1.5mm, which works out to 0.059055″. Most of the PPC/BR flash-hole uniforming tools on the market use a 1/16″ bit which is nominally 0.0625″, but these often run oversize — up to 0.066″.
If you want to just clear out any obstructions in the flash hole, without increasing the flash hole diameter, you can use an inexpensive “pin vise” with an appropriate drill bit. For $1.00, eHobbyTools.com sells a 1.5mm pin vise bit, item 79186, that matches the Lapua flash hole exactly. Other vendors offer a #53 pin vise bit that measures .0595″ or .060″ (depending or source). An 0.0595″ bit is close enough. You can find pin vises and bits at hobby stores.

Hornady offers a handy power case prep tool driver (item 050160) with three power stations. Hornady basically took its previous single-drive Power Case Prep Assistant (item 050155) and added gearing to run three different heads. It took some clever engineering to accomplish this while maintaining the small footprint of the original one-head machine. MSRP for the new Case Prep Trio (item 050160) is $129.39. If you can live with a single power take-off, the older one-head Case Prep Assistant is still offered on “close-out” at some vendors. If you look around you may find one for as little as $79.99.
Hornady calls its updated machine, with 3-tool capacity, the Lock-N-Load® Case Prep Trio. With three active stations, you can chamfer, deburr and clean primer pockets without having to change tools. The Case Prep Trio ships with inside chamfer, outside chamfer, and deburr tools. You can also use the machine with other optional 8/32 threaded accessories such as primer pocket reamers and case neck brushes. Conveniently, the Case Prep Trio has on-board storage for your tool-heads.

Forum member Danny Reever and this Editor recently discussed how novice reloaders can struggle with the fine points of reloading, making errors in seating depth, bushing choice, or sizing their cases. We agreed that a good resource covering more than “Reloading Basics” is sorely needed. Danny reminded me that Glen Zediker’s excellent Handloading for Competition book has been available since 2002. Danny says this may still be the best guide in print for those getting started in precision reloading, though the book is not without flaws.
Danny observed: “I consider this still the best book out there on the subject. I’ve bought a lot of other books only to be sorely disappointed after spending $30-$40 of my hard-earned cash. This book is not one of those! I’ve read and re-read Zediker’s treatise at least four times and refer to it often for advice while reloading. My number one suggestion for those who buy the book is to sit down with a highlighter and read it cover to cover. It’s well-written with a bit of humor and it is not boring.”
Extremely comprehensive, Zediker’s book covers nearly all of the key factors involved in accurate reloading: case sorting, brass prep, load development, neck-sizing, full-length sizing, bushing selection/use, tool selection, priming, powder measurement, and bullet seating. The book also explains how to test and evaluate your ammo, and how to monitor and interpret pressure signs.
There are many “must-read” sections in Zediker’s book, according to Danny: “The section beginning on page 161 dealing with concentricity (and how to achieve it) is excellent. Likewise the Load Limits section discussing pressures offers very valuable advice and info. You should also read Zediker’s commentaries about load testing, powders (burn characterics etc.), and the effects of temperature.”
Zediker has conveniently provided a detailed summary of his book on the web, complete with table of contents, sample pages (PDF format), and dozens of illustrations. Shown above is just one small section that covers ejectors.
High-volume hand-loaders can save time and effort by using power case prep machines. High Power shooters and varmint hunters, in particular, need to process large quantities of cartridge brass. One of the more versatile power case prep units on the market is the new Case Prep Xpress from Lyman. With five (5) power take-offs conveniently arranged on top of the machine, you can perform multiple functions quickly. Watch the video to see the unit in operation.

Here’s a user review from a Lyman Case Prep Express Owner: “The Lyman unit has more than adequate power/torque, unlike some other case prep units on the market, plus a solid exterior case, plus a decent selection of threaded tools. I’ve prepped several thousand cases without a hitch. I have no complaints or criticisms.”

Hornady has a new, compact, one-station Case Prep Assistant for 2011. This handy, affordable unit easily fits on your benchtop. The dual-voltage (110v/220v) Case Prep Assistant can power inside and outside chamfer tools as well as neck brushes and primer pocket cleaners/uniformers. Included with the Case Prep Assistant are chamfer and deburr tools, with plenty of onboard storage for optional case prep accessories such as primer pocket cleaners, case neck brushes and other 8-32 thread tools. The unit is compatible with both 110V or 220V power. The Case Prep Assistant retails for under $90.00 — Midsouth Shooter’s Supply has it for $83.88 currently.
The new compact Case Prep Assistant complements Hornady’s large Case Prep Center, introduced in 2010. The large prep center performs all case prep functions, including case trimming which is handled by a vertical (drill-press-type) motorized trim station. Cases are held with a cam-lock shell-holder and then lowered vertically on to the spinning trimmer head. Hornady’s Dave Emary demonstrated both products for us at the 2011 SHOT Show. Dave then told us about the Vintage Sniper Rifle Matches which he has helped organize for the CMP.

Lyman has introduced a handy new multi-function Case Prep Tool. Most serious reloaders employ a variety of tools to chamfer and de-burr case mouths, and to clean and uniform primer pockets. As you may need four or five separate tools to do all these tasks, keeping track of all those gadgets can be a challenge. The Lyman Case Prep Multi-Tool makes life simpler. The Multi-Tool comes with six matching tool-heads, all of which conveniently store inside the orange-anodized aluminum handle.
Lyman’s new double-ended Case Prep Multi-Tool is a smart design. It holds tools on both ends, and the orange handle unscrews in the middle to provide secure storage for all necessary case prep fittings: Outside Deburring Tool, VLD Inside Deburring Tool, Large & Small Primer Pocket Cleaners, and Large & Small Primer Pocket Reamers. Both ends of the handle are threaded, allowing two heads to be mounted at the same time.
COMMENT: Priced at $24.95 MSRP, the Lyman Case Prep Multi-tool is a good value, considering what it would cost to buy a full set of case prep tools one by one. However, we wish some of the tool heads had better cutting edges out of the box. For the Multi-tool heads (as with most Lyman cutting tools), you’ll benefit by honing the cutting edges with a good whetstone or blade sharpener.

Gas gunners take note — for 2010 Redding has created new “National Match” reloading sets in .223 Remington, .308 Winchester, and 30-06 Springfield. These new three-die sets are designed expressly for the AR15, M1A, and M1 Garand used in High Power comps and Garand matches. These kits include a full-length sizing die, a Competition Seater Die, and a taper crimp die. Previously these dies were only offered individually. If you’re shooting an AR, Garand, or M1A, these new sets may be just what you need.
In addition to the National Match die sets, Redding has added new calibers to its die catalog for 2010. Complete die sets will now be offered for the popular 6.5 Creedmoor, the 260 Rem Improved 40° (also know as the 260 Ackley), and the 458 Socom. This should please the growing numbers of High Power shooters using the 6.5 Creedmoor, and the tactical guys looking for more velocity than a standard 260 Rem can deliver.
New Complete Basic Reloading Set
For shooters just getting started in reloading, Redding has put together a new basic reloading package that contains virtually everything you need except a press and dies. Redding’s new Versa Pak includes a reloading scale, powder measure, case trimer, powder trickler, case lube pad, funnel, deburring tool, and other case prep tools. In addition, the Versa Pak comes with the Hodgdon Reloading Manual and Redding’s excellent Advanced Handloading DVD. The Versa Pak will retail for about $350.00. That may sound like a lot, but if you add up the cost of all the gear included in the Versa Pak, it is a good value. You’ll also save time (and shipping costs) by acquiring all the essential tools at one time.
