Expanding Cartridge Brass in Stages with Progressive Press

Darrell Jones DJ's Brass Service expanding brass 6mmBR 6BR BRX 30BR Hornady press
Photos from DJ’s Brass Service.

Have you ever expanded a .22 or 6mm cartridge all the way up to .30-caliber? If so, you know this can be a difficult procedure that stresses the case necks and neck-shoulder junction. A significant neck-size expansion done in one big jump can increase run-out, cause doughnuts, or worse yet, even split the brass. Therefore you want to proceed in increments, increasing the neck diameter in stages. One smart way to do that is to use a Progressive Press. This article explains how…

The most successful short-range benchrest-for-score cartridge is the 30 BR. That cartridge, as well as 30 BR variants such as the 30 BRX, all start with the 6mmBR Norma parent cartridge, typically with Lapua 6mmBR brass. To get a nice 30 BR case you want to expand in stages, increasing the inside neck diameter incrementally from .243 to .308.

Darrell Jones of DJ’s Brass Service creates thousands of 30 BR cases each year. He has found a clever way to speed up the process — Darrell uses a Progressive Press. He runs his 6BR brass through four (4) separate Hornady neck-sizing dies with expander mandrels. First there is a .257 die, followed by .264 (6.5mm), .284 (7mm), and then .308. Then a fifth and final K&M die provides one last, slight expansion so the newly-fashioned 30 BR cases perfectly fit the arbor of Darrell’s neck-turning tool.

So to repeat, the case starts as .243 (6mm), then moves in up stages .257, .264, .284, and .308, with a final “finishing” step prior to neck-turning. You can see the expansion in this video, which starts with 6mmBR brass that was first hydro-formed to 6 BRX:

Watch 6mm Cases Expanded to 30-Caliber (6BRX to 30 BRX)

For this demo video, Darrell expands just one case at a time. However, he can also put multiple cases in the progressive — one per station. This takes a little more effort, Darrell says, but the results are still excellent. Darrell tells us: “I do put multiple cases in the progressive to save time. The results are the same — I just wanted to show a single-step process and how it reduces run-out by not stressing the shoulder with one big expansion from 6mm straight to 30 caliber. Doing the operation in multiple stages avoids binds and helps keep the shoulders concentric.”

This same multi-stage procedure can be use to expand other cartridge types. For example you could take .221 Fireball brass in stages up to .308 to create 300 Blackout brass.

Darrell uses caliber-specific, Hornady neck-sizing-only dies with elliptical expanders. Darrell tells us: “The Hornady elliptical expander has a reduced bearing surface that puts less strain on the brass when expanding the necks to the next size.” The fitting at the bottom of the die is the Lock-N-Load die bushing that allows fast die changes.

These particular cases used in the video were first hydro-formed to 6BRX then expanded to 30 BRX before neck turning. DJ’s Brass offers hydro-forming for many popular wildcat cartridges such as 6 PPC, 6mm Dasher, and .284 Shehane.

Progressive Presses — Video Showcase of Six Machines

ultimate reloading progressive press review dillon Mark 7 rcbs lee hornady

COVID-19 stay-at-home orders have created abundant free time at home for millions of Americans. To fill otherwise empty hours, we know many readers have been reloading ammo — LOTS of ammo. And quite a few of you folks are thinking of getting a progressive press to increase output. Because multiple operations take place with a single pull of a lever, a progressive press can produce way more ammo in a given period of time than any single stage press. With a progressive, on the ram up-stroke, the multiple stations can simultaneously remove spent primer, full-length size case, drop powder, seat bullet, and crimp (if desired). Most progressives are also set up to prime cases with the ram in the lower position — though some guys prefer to prime manually.

Progressive presses aren’t just for high-output pistol ammo or bulk rifle ammunition. Good progressives can be adapted to do certain reloading tasks for top-on-the line match ammo. You might use a progressive for decapping, priming, and sizing, then throw powder and/or seat bullets separately. Some Champion shooters do use progressives to load their match ammo! For example 5-Time National Long Range Champion John Whidden and 2020 Berger SWN F-Open Champion Jay Christopherson both use progessive presses for some (but not all) operations.

To help you get started with progressive presses, here are five videos from UltimateReloader.com that cover six popular machines, from the elite Mark 7 Evolution to the inexpensive Lee Pro 1000. With many of these machines you can add separate vertical bullet feeder systems that further increase loading efficiency.

Introduction to Auto-Indexing Progressive Presses

USAMU Progressive Press auto  self-advancing

On Wednesdays, The U.S. Army Marksmanship Unit regularly publishes reloading “how-to” articles on the USAMU Facebook page. One “Handloading Hump Day” article, part 5 of a 6-part series, relates to reloading on Progressive Presses. This article concerns proper procedures for Auto-Indexing Progressives, which advance the shell-plate with every pull of the handle. Auto Progressives are very efficient, but they also require special attention and focus, because so many things are happening at once. You need to train yourself to watch every station. If you run a progressive press now, or are considering getting a progressive, we recommend you read this article. Visit the USAMU Facebook page for other helpful handloading guidance.

Progressive Loading Presses — Self-Advancing Shellplate Type

USAMU Progressive Press auto  self-advancing
Photo courtesy UltimateReloader.com.

Recently, we addressed manually-operated progressive presses for the beginning handloader. This type press requires one to manually advance the shellplate after each handle stroke. An advantage for beginners is that nothing happens at any station until the loader wants it to. This helps users avoid problems from clearing malfunctions without noticing that the shellplate has advanced itself. (Read Previous USAMU Article on Manual Progressives.)

The next, more luxurious type progressive press advances the shellplate automatically whenever the handle is cycled. [Editor: This is also called an “Auto-Indexing” Progressive Press.] Typically, each stroke automatically sizes and primes a case, operates the powder measure (if used) and seats a bullet. Some also have case feeders that automatically put a new case in the shellplate with every cycle. Others require the loader to insert a case each cycle. With both types, the loader usually puts a bullet on each sized/primed/charged case.

[CAVEAT: While our Handloading Shop has several progressive presses, ALL of our powder charges are thrown/weighed by hand. We do not use powder measures on our presses. Our progressives are used for brass preparation, priming, seating, etc., but not for fully-progressive loading.]

The manually-advanced press can be a boon to beginners, but as one gains experience it can be a mixed blessing, depending on one’s style. If one pays close attention to every operation and loads without distractions, the manual press is very reliable and allows full scrutiny of each round as it is loaded. However, if one easily drifts into day-dreaming, or isn’t focused on paying careful attention at all times, the manual progressive can be a bit of a liability. The opportunity for forgetting a powder charge, leading to a squib load, is ever-present. [Editor: A lock-out die can help reduce the risk of a squib load, or a double-charge. See below.]

The automatically-advancing progressives help prevent this by ensuring a powder charge will be dropped each time the handle is operated. Experienced handloaders often appreciate this feature due to the savings of time and effort. Individual preferences between the two press styles are influenced by several factors. These include one’s comfort with more- vs. less-complicated mechanisms, how often one changes calibers (case feeders often must be converted, in addition to dies and shellplates), how many rounds one loads annually, relative ease of changing primer mechanisms from small to large, etc. Automatic progressives and their caliber conversion kits tend to be significantly more expensive than manual progressives and caliber conversions from the same maker.

One USAMU handloader, who likes simple, bullet-proof machines and maximum efficiency when converting presses, owns two manually-advanced progressives. One is set up for large primers, and the other for small primers. He can change calibers in the twinkling of an eye. As he loads for many different calibers, this fits his style. Another handloader here is just the opposite. He loads for a few calibers, but in larger quantities. He much prefers his self-advancing press with case-feeder for its speed. He makes large lots of ammo in a given caliber before switching, to improve overall efficiency. His caliber conversion kits are more expensive than those for the manually-advanced progressive, but he uses fewer of them.

Whichever type one chooses, it is VERY important to buy quality gear from a manufacturer with a long, well-established track record for quality, durability and good customer support. Avoid jumping on the “latest, greatest” model until it has a proven track record. For example, this writer knows a loader who got a brand-new, expensive, self-advancing model press some years back, shortly after its introduction. As is too often the case these days, the manufacturer released it before all the “bugs” were worked out.

Better Safe Than Sorry — the RCBS Lock-Out Die
RCBS Makes a “Lock-Out Die” that senses the powder charge. This will halt the Progressive press if you have a double charge, or an undercharge. Your Editor has the Lock-Out Die on his RCBS Pro 2000. It has “saved his bacon” a half-dozen times over the years. It can be used on Dillon and Hornady progressives as well as RCBS machines.

It would not fully seat primers to the correct depth. No amount of adjustment, extra force, or fiddling would do better than to seat primers barely flush with the case head. Any inattention could result in a slightly “high” primer, protruding above the case head. It created a risk for slam-fires, particularly in semi-autos without spring-retracted firing pins, such as the M1 or M1A. In desperation, he had a machinist buddy study the problem and machine a new part to correct it. No dice. Its engineering didn’t permit full primer seating, even with extended parts. He now wishes he’d heeded his shooting buddies’ advice to stick with the “tried and true,” reliable performer they all used.

Whichever press one selects, see if the maker has a kit or list of commonly-replaced parts. Having needed springs, pins, etc. on hand in the rare event that one breaks or “goes missing” can save the day when one is busy loading for a match! Another tip for improving one’s overall loading efficiency (rounds loaded with minimal set-up/tear-down time) is to plan one’s handloading by primer size. For example, if your machine is set to use small primers, load all the calibers that you intend to that take small primers, before converting the press to load large-primer calibers.

In our next chapter, we’ll discuss peculiarities of progressive loading for rifle cartridges, with remedies for problems such as excessive cartridge-case headspace variation when sizing, tips for ensuring best powder charge consistency, and so on. Until then, be safe, and good shooting!

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.

USAMU Tips for Using a Progressive Reloading Press

Accurateshooter.com USAMU progressive press reloading

Each Wednesday, the U.S. Army Marksmanship Unit (USAMU) publishes a reloading “how-to” article on the USAMU Facebook page. In this article, the USAMU’s reloading gurus help you avoid potentially disastrous mistakes with a progressive — such as double powder changes. The USAMU experts caution that: “beginners would be better served by starting on a single-stage press”. That said, owning a progressive makes sense if you shoot more than 100 centerfire rounds a week. If you own a progressive press, or are thinking of buying one, you should read this article.

USAMU Reloading

For those interested in progressives, we’ll examine different key features among the types and relate them to handloading processes. The first, and simplest, type is the manually-advanced progressive. The shellplate holds the several cartridges being processed with each stroke of the handle. On these presses, the loader must manually advance the shellplate after each handle stroke.

While this obviously slows production vs. a press that cycles the shellplate automatically, this feature does have advantages though. (The disadvantages follow shortly.) No case is advanced to the next station until the operator deliberately does so – which is especially helpful for the new handloader.

Problems that arise during loading can be diagnosed and fixed without fears of some “extra” operation happening unnoticed with cartridges at the other stations. Beginners NOTE: one way to positively prevent this risk is to remove the cases from each press station when a problem emerges, before beginning diagnosis. Usually, however, experienced loaders omit this step as a time-saving measure, being confident in their understanding of the loading machine, process and the appropriate remedy.

Progressive press reloading ultimate reloader USAMU

If all cartridge cases are left in place, the operator must monitor what’s happening at each station. For example, raising the press ram twice may result in a double-charge of powder. With rifle cartridges, this usually results in a massive powder over-flow, alerting the loader to the problem. With pistol cases or small rifle charges in large cases, such an over-flow isn’t guaranteed. [Editor — one way to be sure you don’t have an overcharge or undercharge is to use a Lock-Out Die — see below.] The manually-advanced progressive keeps all operations under the loader’s control at all times. This is intuitively easier for the beginning loader to understand and to operate with confidence.

However, this same characteristic can be problematic if the loader isn’t paying 100% attention to what they are doing during routine operation. Some new handloaders apparently aspire to load progressively while daydreaming and paying little attention to the operation. Their plan is to feed components in, like feeding potato chips to a monkey, while good ammo drops out at the other end. Unfortunately, such an approach may likely result in something other than “good” ammo dropping out at the end…

Forgetting to cycle the shellplate when appropriate will cause problems. As with all handloading, distractions MUST be kept to a minimum for safety purposes. Never watch TV, talk with friends, or have other distractions (such as a rambunctious pet or child) in the room when loading. Avoiding distractions will do much to ensure that one produces consistent, high-quality ammunition, free of defects. For example, when a case doesn’t line up correctly with the case mouth expander or powder drop tube, a difference in “feel” often alerts the loader to correct the problem without ruining a case. If one is interrupted or becomes distracted, be certain to examine ALL cases in the shellplate before resuming loading.

Better Safe Than Sorry — the RCBS Lock-Out Die
RCBS Makes a “Lock-Out Die” that senses the powder charge. This will halt the Progressive press if you have a double charge, or an undercharge. Your Editor has the Lock-Out Die on his RCBS Pro 2000. It has “saved his bacon” a half-dozen times over the years. It can be used on Dillon and Hornady progressives as well as RCBS machines.

Other advantages of the typical manually-advanced progressives are that they are usually simpler in design, with fewer moving parts to get out of adjustment. This appeals to the mechanically dis-inclined! Caliber conversion kits are usually cheaper and take less time to install. This especially benefits the enthusiast who reloads for a wide variety of calibers.

However, many popular manually-advanced progressives have fewer die stations than the higher-end, auto-advancing machines. One item that is very useful when actually dispensing powder on a progressive press is a cartridge case powder-level sensor. This warns if powder levels in each case are too high or too low; however, it does require a die station of its own.

This condition (incorrect powder charges) often results from powder (especially extruded rifle powder) “bridging” in the powder measure. That is, one charge doesn’t fully empty into its cartridge case. This leaves some extra powder hanging up in the measure to join the normal charge in the next case. With some extruded powders, this can be quite obvious without a sensor. However, the sensor can detect small variations that would not be obvious to even an experienced, attentive operator. Considering the machine’s potential to use a powder sensor in addition to one’s other customary dies is a wise idea.

Similarly, pistol shooters are best served to seat bullets and crimp cartridges in separate operations. This should be taken into account when selecting a progressive press. Whenever loading fully-progressively, choosing powders that dispense very easily, e.g., ball/spherical or very fine-grain extruded powders, can help keep charges quite uniform.

Precision Handloading for Pistols — Tips from the USAMU

USAMU Service Pistol Handgun Tip Advice Reloading

Each Wednesday the USAMU offers tips for handloaders on the USAMU Facebook page. This article from the “Handloading Hump-Day” archives should interest pistol competitors, an any shooter who enjoys getting the best possible accuracy from their fine pistols. In this article, the USAMU’s experts share key tips that can help optimize your pistol ammo. Follow this tips to produce more consistent ammo, that can shoot higher scores.

Optimize the Taper Crimp
One often-overlooked aspect of handloading highly-accurate pistol ammunition is the amount of crimp and its effect on accuracy. Different amounts of taper crimp are used with various handloads to obtain best accuracy. The amount is based on bullet weight, powder burn rate and charge, plus other factors. It is not unusual for our Shop to vary a load’s crimp in degrees of 0.001″ and re-test for finest accuracy.

USAMU Service Pistol Handgun Tip Advice ReloadingUse Consistent Brass
Brass is also important to pistol accuracy. While accurate ammunition can be loaded using brass of mixed parentage, that is not conducive to finest results, particularly at 50 yards. It is important for the serious competitor/handloader to use brass of the same headstamp and ideally one lot number, to maximize uniformity. Given the volumes of ammunition consumed by active pistol competitors, using inexpensive, mixed surplus brass for practice, particularly at the “short line” (25 yards), is understandable. However, for the “long line” (50 yards), purchasing and segregating a lot of high-quality brass to be used strictly for slow-fire is a wise idea.

Importance of Uniform COAL
Uniformity of the Case Overall Length (COAL) as it comes from the factory is also important to achieving utmost accuracy. More uniform case lengths (best measured after sizing) contribute to greater consistency of crimp, neck tension, ignition/burn of powder charge, and so on. Cartridge case-length consistency varies from lot to lot, as well as by maker. Some manufacturers are more consistent in this dimension than others. [Editor’s note: It is easy to trim pistol brass to uniform length. Doing this will make your taper crimps much more consistent.]

Primers and Powders — Comparison Test for Accuracy
Pay attention to primer brands, powder types and charges. Evaluating accuracy with a Ransom or other machine rest at 50 yards can quickly reveal the effect of changes made to handload recipes.

USAMU Service Pistol Handgun Tip Advice Reloading

Bullet Selection — FMJ vs. JHP
Bullets are another vital issue. First, there is the question of FMJ vs. JHP. A friend of this writer spent decades making and accuracy-testing rifle and pistol bullets during QC for a major bullet manufacturer. In his experience, making highly-accurate FMJ bullets is much more difficult than making highly-accurate JHPs, in large part due to the way the jackets are formed. Small die changes could affect accuracy of FMJ lots dramatically.

The CMP now allows “safe, jacketed ammunition” in Excellence-in-Competition (EIC) Service Pistol matches, although wadcutter ammunition is prohibited. Thus, the option to use very accurate JHP designs simplifies the life of CMP Service Pistol shooters in pursuit of the prestigious Distinguished Pistol Shot badge.

Hopefully, these tips will be helpful to any pistol shooters interested in accurate handloads, not just “Bullseye” shooters. Small tweaks to one’s normal routine can pay big dividends in improved accuracy and make practice and competition more rewarding.

Stay safe, and good shooting!

Keepin’ It Safe: Seven Tips for Reloading Safety

seven reloading safety tips powder primers brownells manual

You can never be too safe when hand-loading your own ammunition. This helpful Brownells video outlines the Seven Fundamental Reloading Safety Tips. This is important information for novice hand-loaders and a good refresher for those with reloading experience!

Summary of the Seven Safety Tips:

1. Store your reloading supplies in a safe and dry location, away from children and away from any possible source of ignition. It is also smart to keep your powder and primers separate.

2. Get and use respected reloading manuals, especially for new cartridges. Start low and work up slowly while watching for warning signs of pressure and/or case fatigue.

3. Locate your reloading activity where you will not be distracted. If you get interrupted, stop. (Distractions will eventually lead to mistakes.)

4. Do NOT mix powders. Keep your powders clearly marked and dated. You can use masking tape to write the date on the container.

5. If you load the same cartridge type for different firearms, make sure your ammo headspaces properly in each gun.

6. Check cases frequently. Look for split necks, case head separation or other signs of fatigue and excessive pressure.

7. If reloading military brass, be aware that case capacity is usually reduced, and initial loads should be at least 10-15% lower than published data.


Here are some other tips that will help your avoid making costly mistakes (such as using the wrong powder, or undercharging a case):

  • Powder Type — Always double-check the label on your powder containers. After placing powder in the powder measure, put a piece of tape on the measure with the powder type written on it. Some guys write the powder type on a card and place that right in the hopper.
  • Scale Drift — Electronic balances can drift. If you are using a digital powder scale, calibrate the scale with a test weight every 50 rounds or so.
  • Case Fill — If you throw more than one charge at a time, look INSIDE every case before seating a bullet. Squib charges can be dangerous if you don’t notice them before firing the next round.
  • Progressive Presses — When using a progressive press, consider using an RCBS Lock-Out Die. This will detect a low charge and stop the machine. These dies will work with RCBS, Hornady, and Dillon progressives.

USAMU Advice for Progressive Press Users

Accurateshooter.com USAMU progressive press reloading

Each Wednesday, the U.S. Army Marksmanship Unit (USAMU) publishes a reloading “how-to” article on the USAMU Facebook page. In this article, the USAMU’s reloading gurus address a question frequently asked by prospective handloaders: “Should I buy a single-stage press, or a progressive?” The USAMU says the best answer is Solomon-esque in both its wisdom and simplicity: “Get BOTH!” However, there is definitely more to the issue, as the USAMU explains below.

USAMU Reloading

Progressive Press Safety Considerations by USAMU Staff
Many are the beginning handloaders who have asked a friend about their “setting up” a progressive press for them. The idea is that the newbie could then just feed in components and crank out buckets of practice ammo without needing to really learn much about handloading. Tempting though this might be, that’s simply not how it works. Such an approach might be ok if there were never a malfunction with either press or operator, but that’s unrealistic. Our hypothetical newbie would then lack the knowledge to problem-solve most situations.

Worse yet, several different handloading operations would be occurring at different stations on the progressive press at the same time. It takes an experienced operator to keep track of, and truly understand the significance of, all those potential mini-problems. Loading without this experience is a recipe for potential disaster – such as a double powder charge (especially with pistol cartridges) dropped while the loader was attending to some other function, etc. Progressives are an animal unto themselves, and while they offer many benefits, they do take some getting used to – even by experienced handloaders!

ILLUSTRATIVE HORROR STORY
Here, enter a 40-year veteran handloader who decided to jump onto the progressive bandwagon late in his career, having used only single-stage presses all his life. A High Master NRA High Power Rifle competitor, he had no background in competitive pistol shooting, where historically most progressive presses are found.

Experienced Action Pistol shooters have typically encountered multiple episodes in which shooters “skipped” a powder charge for some reason, leading to a squib round and a bullet possibly lodged in the bore. Thus, at matches, it’s reflexive for them to yell “STOP!” in unison if they see a shooter get a “click” vs. a “bang”, and rack the slide to keep firing. This writer has personally seen several pistols saved in just such scenarios over the years.

Click No Bang — What NOT to Do
Our High Master set up a popular progressive press and began turning out .223 Rem 100-yard practice ammo with abandon. He was using a moly-coated 52gr match bullet and an economical, fast-burning surplus powder that gave great accuracy. Once on the range, he began practicing strings of rapid-fire. All was well, until he heard “Click!” rather than “Boom”.

Lacking the above experience or onlookers to halt him, he reflexively operated the charging handle on his expensive, custom NM AR15 Service Rifle, and the next trigger squeeze reportedly registered on seismographs over at least a three-state radius. He sat, uninjured but bewildered, until the hail of expensive bits and pieces quit raining down around him.

When the smoke cleared, he immediately cursed the horrid, evil, demonically-possessed progressive press for this, his first-ever reloading mishap. His $1400 NM upper was ruined, but thankfully, his $800 pre-ban lower… and he had escaped injury.

This tale is told not to discourage the use of progressive presses, but to emphasize the need to EASILY and IMMEDIATELY KNOW what is happening with the press at each station, every time the handle is cranked. Not to do so is, as they say, “bad ju-ju.”

It illustrates why we at the USAMU Handloading Shop agree in recommending that new handloaders should begin with a single-stage press. Once one thoroughly learns the steps in each phase of handloading by repeated experience, then one will be qualified to move on to a progressive press.

The single-stage press will REMAIN virtually indispensable for one’s entire handloading career, even after having purchased a progressive press (or two). There are endless small projects that are best handled on a single-stage press, and a poll of USAMU’s Handloading staff reveals that not one would willingly be without his single-stage press, despite owning at least one progressive.

A typical order for this shop may be 25,000 rounds, so [speeding up] the lubrication process can be a real time-saver. While your ammunition lots probably aren’t this large, the efficient methods discussed here may help save a considerable amount of time over your handloading career. Our case lubrication rates range from 1500-1600 cases per hour, to 2400-2500 cases per hour, depending on caliber.

This shop uses virgin brass, whereas most home handloaders use fired brass, which necessitates some small changes at times. These will be discussed as they arise. Begin with fired brass that has been tumbled clean.

Ensure as much tumbling media as possible is removed from the brass, as when it gets into a size die, it can dent cases significantly. This is a good time to round out dents in the case mouths using a tapered tool to prevent damage from the decapping stem.

First, dump the clean cases into a large box or reloading bin. Shake the bin back and forth so that many cases are oriented with the mouths up. Next, pick up as many cases as is convenient with the mouths “up”, from natural clusters of correctly-oriented cases. With 7.62mm-size cases, this is usually 3-4, and with 5.56mm cases, this can be up to 8-10. Place the cases into the rack slots, mouth-up. Doing this in groups rather than singly saves considerable time. Once these clusters have been depleted, it will be time to re-shake the bin to orient more cases “up.”.

Naturally, adjust the spacing to best fit the calibers you reload. We have found this size … convenient for handling through the various phases of case lubrication/transfer to progressive case feeders for processing. Note that the 1/2-inch angle does not cover much of the critical case area at the base, just forward of the extractor groove, where most re-sizing force will be exerted. As the USAMU uses virgin brass, less lubrication is required for our brass than would be needed for Full Length (FL) sizing of previously-fired brass.

NOTE: The amount applied using our rack is easily enough for our purpose. If using fired brass, be sure to adequately lube this base area to avoid having cases stick in the full-length sizing die.

Using a spray lube, coat the cases adequately, but not excessively, from all sides. Be sure to get some lube into the case mouths/necks, in order to reduce expander ball drag and case stretching/headspace changes. The spray lube this shop uses does not harm primers or powder, and does not require tumbling to remove after lubing.*

Take a close look at the photo above. The USAMU shop uses a common kitchen turntable, which allows the rack to be rotated easily. We place this in a custom-made box which prevents over-spray on to floors and walls.

Angled Box Method for Smaller Cases to be Neck-Sized
A refinement of the above method which especially speeds processing of 5.56x45mm cases is as follows. A small cardboard box which holds about 100 cases is fitted with an angled “floor” secured by tape. With the smaller 5.56mm cases, usually about 8-10 cases per handful can be picked up, already correctly-oriented, and placed into the box together. This prevents having to place them into the rack slots, saving time.

HOWEVER, note that this does not allow nearly as much lube access to the case bodies as does the rack. For our purposes — neck-sizing and setting neck tension on new brass, this works well. If using this procedure with fired brass, take steps to ensure adequate lube to prevent stuck cases.

As always, we hope this will help our fellow handloaders. Good luck, and good shooting!


*A two-part test performed here involved spraying primed cases heavily, while getting more lube into the case mouth/body than even a careless handloader would likely apply. The second part of the test involved literally spraying considerable quantities of the lube directly into the cases, drenching the primers. After a several-day wait to allow the lube to penetrate the primers, they were then fired in a test barrel. All fired normally; no unusual reports were noted. This bolstered confidence that normal amounts of the lube would not adversely affect our ammunition, and we have been pleased with the results over several years.

Primer Seating Depth Uniformity and Accuracy

Each Wednesday, the U.S. Army Marksmanship Unit publishes a reloading “how-to” article on the USAMU Facebook page. Yesterday’s post covered primer seating depth. This article offers many useful tips — including a clever way to measure primer seating depth with ordinary jaw-type calipers. Visit the USAMU Facebook page next Wednesday for the next installment.

USAMU reloading tip

Primer Seating Depth — Why Uniformity is Important
The first concern is for safety: for that reason, primers should be seated below flush with the case head. One primary cause of “slam fires” (which includes catastrophic failures from firing out of battery) is “high,” or protruding primers. These stand above the case head, are readily felt with simple finger-tip inspection, and may fire when slammed by the bolt face and/or a floating firing pin in feeding.

Here at the USAMU, we ensure our rifle primers generally run -0.003″ to -0.005″ below the case head. Maximum primer depth is -0.006″ and minimum is -0.002″. Upon inspection, any cases with high primers will be corrected before loading. Aside from improving ballistic uniformity, ensuring the primers have proper compression upon seating also helps reduce possible misfires. These can be caused by the firing pin’s expending part of its energy either seating the primer or having to deform the primer cup enough to reach the anvil.

SMART TIP: How to Measure Primer Seating Depth with a Set of Calipers
A zeroed, precision set of standard calipers will also measure primer seating depth. (You don’t really need a custom tool.) Merely close the jaws and place the calipers’ narrow end squarely across the center of the case head/primer pocket. Keeping the narrow end in full contact with the case head, gently open the jaws, and the center bar will extend until it reaches the primer face. Voilà! Primer depth is read on the dial. Taking a few measurements to ensure accuracy and repeatability is recommended until one is familiar with this technique.

Brass and Primer Defects Can Cause Seating-Depth Variances
Factors affecting variance of primer seating depth include brass maker and lot number — all primer pockets are not created equal! Another factor is the primer manufacturer and individual primer lot. We’ve encountered occasional primer lots by top-quality makers that included some primers with slight defects affecting seating. While finely accurate, these primers were out-of-round or had small slivers of cup material protruding which affected primer feeding or seating depth.

Has one’s brass been fired previously? If so, how many times and the pressures involved also affect future primer seating. Obviously, this is another factor in favor of segregating one’s high-accuracy brass by maker, lot number, and number of times fired, if possible.

Measuring Primer Seating Depth with Purpose-Built Gauge
The next question, “How do we measure primer depth?” happily can be answered using tools already owned by most handloaders. [See tip above on how to measure depth with calipers.] At the USAMU, we have the luxury of purpose-built gauges made by the talented machinists of the Custom Firearms Shop. One places the primed case into the gauge, and the dial indicator reads the depth quickly and easily. The indicator is calibrated using a squarely-machined plug that simulates a case head with a perfectly flush-seated primer, easily giving meaningful “minus” or “plus” readings. The gauge is usable with a variety of case head sizes.

Primer Seating with Progressive Presses
Methods of primer seating include hand-seating using either hand held or bench-mounted tools, vs. progressive-press seating. Progressive presses may either seat by “feel,” subjective to each operator, or by using a mechanical “stop” that positively locates primers nearly identically every time. Testing here has shown that we get more uniform seating with the latter type progressive press, than we do with a high-quality bench-mounted tool lacking a positive stop.

Primer stop depth adjustments on our main progressive presses involve turning a punch screw in and out. While the screw is not calibrated, fine “tick” marks added to the top of the press help users gauge/repeat settings by “eye” efficiently with practice. Then, once a sample of primed cases is run to confirm the range and accuracy of depths, the identifying lot number and maker is noted on the press for reference. When it’s necessary to switch brass/primer lots, changes are easy to make and settings are easily repeated when it’s time to switch back.
