We know that many of our readers are now tumbling their brass in liquid media rather than dry media such as corn-cob or walnut shells. When done with STM stainless tumbling media (small ss pins), this system really does work, producing brass that is clean “inside and out”. The only down-side to wet tumbling is that sometimes the inside of the caseneck gets so “squeaky clean” that bullets take more effort to seat. This can be remedied with the use of a dry lube inside the necks. When cleaning with stainless tumbling media you’ll need a quality tumbler that is water-tight. The wet-tumbler of choice is the Model B Thumler’s Tumbler. Featuring a bright-red, side-loading drum, the Model B Thumler’s Tumbler is reliable and built to last.
A while back, Bill Gravatt, then President of Sinclair Int’l, had a chance to evaluate the Thumler’s Tumbler and the wet-cleaning process for cartridge brass. Bill came away a believer: “I wanted to share with you my experience using the Thumler’s Tumbler and stainless steel pin media to clean brass.
What’s the next best thing to a stockpile of gleaming, freshly-loaded ammo? How about a movie showing gleaming, freshly-loaded ammo being made — from start to finish? The five-minute video below shows the ammunition production process at the Lake City Army Ammunition Plant, a division of ATK. Lake City is the largest producer of small arms ammunition for the U.S. military, producing roughly four MILLION small-caliber rounds every day.
This promotional video does go a bit overboard at times in a self-congratulatory sense. But the video is definitely worth watching — it is fascinating to watch the process of creating cartridges — from the drawing (or extrusion) of raw brass into casings to the placement of projectiles and primers.
Quick History of Lake City Ammunition Plant Lake City Army Ammunition Plant (LCAAP) is a 3,935-acre government-owned, contractor-operated facility in Independence, Missouri that was established by Remington Arms in 1941 to manufacture and test small caliber ammunition for the U.S. Army. The facility has remained in continuous operation except for one 5-year period following World War II. As of July 2007, the plant produced nearly 1.4 billion rounds of ammunition per year. Remington Arms operated the plant from its inception until 1985, when operations were taken over by Olin Corporation. From April 2001 through the present, it has been operated by Alliant Techsystems (ATK), which in February 2015 split into two separate companies, Orbital ATK and Vista Outdoors.

Here’s something you don’t see every day — pistol-caliber Lapua brass. We shoot superior Lapua brass in our rifles, and now you can get the “good stuff” for your 9mm pistols too. It’s nice to know that Lapua 9mm brass is available for those guys who accept “nothing but the best”. Grafs.com received a special order of 9mm Luger (aka 9x19mm or 9mm NATO) pistol brass made by Lapua. It is available right now for $19.99 per 100-count bag or $179.99 per 1000-count box. That’s 38% off the regular 1K box price.
When It Pays to Shoot Premium Pistol Brass
Is this Lapua 9mm brass worth the price compared to the cheaper alternatives (such as once-fired police range pickups)? We think the answer depends on your application. If you shoot a 9mm pistol in Bullseye competition, yes it makes sense to get the Lapua. Or, if you have a 9mm revolver that carries the shells in a moon clip, the Lapua brass may be worth getting. With a 9mm revolver, your brass is not marred by an extractor claw and then ejected on to the ground. If we had the impressive new 8-shot, Miculek Edition Smith & Wesson model 929 9mm revolver (below), we’d definitely shoot Lapua brass.

Forum member Erik Cortina recently launched his own YouTube Channel dedicated to precision reloading and accurizing. Erik’s videos demonstrate the proper use of specialized reloading tools and provide helpful hints. Erik’s latest video is about the “mother of all brass trimmers”, the Giraud powered case trimmer. Erik says: “It you do volume reloading… this is the only trimmer to get. It not only trims to length but it also chamfers your case mouth inside and out.” In his video, Erik offers some very clever and useful tips that will help you get the most from your Giraud.
The Giraud trimmer is very precise. When set up correctly, it can trim brass with amazing consistency. In the video, Erik trims 5 pieces of brass in 15 seconds (6:32 mark). He then measures all five with precision calipers (7:00-8:08). All lengths are exact within .0005 (half a thousandth). Erik notes that the Giraud trimmer indexes off the case shoulder. As long as you have fire-formed brass with consistent base-to-shoulder dimensions, you should get very consistent trim lengths.
The secret to the system is a 3-way cutting head. This cutter can be swapped in and out in a couple minutes with wrenches provided with the kit. Erik has three different heads; one each for 6.5mm, 7mm, and .30 caliber. The video shows how to adjust the cutting heads to match caliber diameter (and to get the desired amount of inside/outside chamfer).
This is a manufacturer’s photo showing an older model.
To trim and chamfer cases, you simply insert them nose-first into the cartridge-specific case-holder. Erick offers a smart tip — He uses a die locking ring to position the cartridge holder (3:15). This can be locked in place. Erik says die locking rings work much better than the hex-nuts provided by Giraud (with the hex-nut, one must re-set cut length each time you change case-holders.)
The Giraud can be used in either horizontal or vertical modes. Erik prefers to have the trimmer aligned vertically, allowing him to push cases down on the trimmer head. But the trimming unit has twin sets of rubber feet, allowing horizontal or vertical orientation.
Improved Case-Holder Made with Chamber Reamer:
For his .284 Shehane, Erik had to create his own case-holder (Giraud does not make one for that wildcat cartridge). Erik used his chamber reamer. To his surprise, Erik found that the brass was easier to trim in the custom case holder (compared to the Giraud-made spring-loaded holders). With a perfect fit, trimming and case extraction went more smoothly and the process was easier on his hands. (See 9:00-10:00). Based on Erik’s experience, you may want to create your own custom case-holder.
Trim Bullet Meplats Also
With a special bullet-holder fitting and meplat cutter head, the Giraud power trimmer can be used to trim bullet meplats. Trimming meplats can help make the Ballistic Coefficents of a batch of bullets more consistent. Uniforming meplats is also often done as a first step in the process of “tipping” bullets to improve BC.

Get an inside look at the how ammunition is made with this step-by-step production guide from Hornady. The video begins by showing the stages in production of a lead-core jacketed bullet with exposed tip, such as the Hornady Interlock. Next, at the 1:38″ time-mark, the video shows how cartridge cases are made, starting with small brass cups (photo right). The brass is lengthened in a series of stages involving annealing, drawing, polishing, and the formation of the case head with primer pocket. Finally, at the 2:40″ time mark, the video shows how bullets and powder are seated into cartridge cases on the Hornady assembly line. In the final production stages, the completed ammunition is tested and packaged.

In our Shooters’ Forum a reader asked: “How much neck tension should I use?” This prompted a Forum discussion in which other Forum members recommended a specific number based on their experience, such as .001″, .002″, or .003″. These numbers, as commonly used, correspond to the difference between case-neck OD after sizing and the neck OD of a loaded round, with bullet in place. In other words, the numbers refer to the nominal amount of interference fit (after sizing).
While these commonly-used “tension numbers” (of .001″, .002″ etc.) can be useful as starting points, neck tension is actually a fairly complex subject. The actual amount of “grip” on the bullet is a function of many factors, of which neck-OD reduction during sizing is just one. Understanding these many factors will help you maintain consistent neck tension as your brass “evolves” over the course of multiple reloadings.
Neck Tension (i.e. Grip on Bullets) Is a Complex Phenomenon
While we certainly have considerable control over neck tension by using tighter or looser bushings (with smaller or bigger Inside Diameters), bushing size is only one factor at work. It’s important to understand the multiple factors that can increase or decrease the resistance to bullet release. Think in terms of overall brass-on-bullet “grip” instead of just bushing size.
One needs to understand that bushing size isn’t the beginning and end of neck tension questions, because, even if bushing size is held constant, the amount of bullet “grip” can change dramatically as the condition of your brass changes. Bullet “grip” can also change if you alter your seating depth significantly, and it can even change if you ultrasonically clean your cases.
Bullet grip is affected by many things, such as:
1. Neck-wall thickness.
2. Amount of bearing surface (shank) in the neck.
3. Surface condition inside of neck (residual carbon can act as a lubricant; ultrasonic cleaning makes necks “grabby”).
4. Length of neck (e.g. 6BR neck vs. 6BRX).
5. Whether or not the bullets have an anti-friction coating.
6. The springiness of the brass (which is related to degree of work-hardening; number of firings etc.)
7. The bullet jacket material.
8. The outside diameter of the bullet and whether it has a pressure ridge.
9. The time duration between bullet seating and actual firing (necks can stiffen with time).
10. How often the brass is annealed
— and there are others…
Seating Depth Changes Can Increase or Decrease Grip on Bullet
You can do this simple experiment. Seat a boat-tail bullet in your sized neck with .150″ of bearing surface (shank) in the neck. Now remove the bullet with an impact hammer. Next, take another identical bullet and seat it with .300″ of bearing surface in another sized case (same bushing size/same nominal tension). You’ll find the deeper-seated bullet is gripped much harder.
Neck-Wall Thickness is Important Too
I have also found that thinner necks, particularly the very thin necks used by many PPC shooters, require more sizing to give equivalent “grip”. Again, do your own experiment. Seat a bullet in a case turned to .008″ neckwall thickness and sized down .003″. Now compare that to a case with .014″ neckwall thickness and sized down .0015″. You may find that the bullet in the thin necks actually pulls out easier, though it supposedly has more “neck tension”, if one were to consider bushing size alone.
In practical terms, because thick necks are less elastic than very thin necks, when you turn necks you may need to run tighter bushings to maintain the same amount of actual grip on the bullets (as compared to no-turn brass). Consequently, I suspect the guys using .0015″ “tension” on no-turn brass may be a lot closer to the guys using .003″ “tension” on turned necks than either group may realize.
Toward a Better Definition of Neck Tension
As a convenient short-cut, we tend to describe neck tension by bushing size alone. When a guy says, “I run .002 neck tension”, that normally means he is using a die/bushing that sizes the necks .002″ smaller than a loaded round. Well we know something about his post-sizing neck OD, but do we really have a reliable idea about how much force is required to release his bullets? Maybe not… This use of the term “neck tension” when we are really only describing the amount of neck diameter reduction with a die/bushing is really kind of incomplete.
My point here is that it is overly simplistic to ask, “should I load with .001 tension or .003?” In reality, an .001″ reduction (after springback) on a thick neck might provide MORE “grip” on a deep-seated bullet than an .003″ reduction on a very thin-walled neck holding a bullet with minimal bearing surface in the neck. Bushing ID is something we can easily measure and verify. We use bushing size as a descriptor of neck tension because it is convenient and because the other important factors are hard to quantify. But those factors shouldn’t be ignored if you want to maintain consistent neck tension for optimal accuracy.
Consistency and accuracy — that’s really what this all about isn’t it? We want to find the best neck tension for accuracy, and then maintain that amount of grip-on-bullet over time. To do that you need to look not only at your bushing size, but also at how your brass has changed (work-hardened) with time, and whether other variables (such as the amount of carbon in the neck) have changed. Ultimately, optimal neck tension must be ascertained experimentally. You have to go out and test empirically to see what works, in YOUR rifle, with YOUR bullets and YOUR brass. And you may have to change the nominal tension setting (i.e. bushing size) as your brass work-hardens or IF YOU CHANGE SEATING DEPTHS.
Remember that bushing size alone does not tell us all we need to know about the neck’s true “holding power” on a bullet, or the energy required for bullet release. True bullet grip is a more complicated phenomenon, one that is affected by numerous factors, some of which are very hard to quantify.

Every year we anxiously await the new product announcement from Lapua. In 2014, Lapua brought out new bullets and new cartridge brass — .221 Fireball and .50 BMG. For 2015, Lapua once again brings out new brass offerings, this time three new flavors of cartridge brass, all made to Lapua’s exacting standards. First, Lapua will introduce factory 300 AAC Blackout (300 BLK) brass. This promises to take this highly-efficient, AR-friendly .30-caliber cartridge to another accuracy level. Second, Lapua will offer premium brass for the 7mm-08 cartridge, a very popular round among hunters and silhouette shooters. Lastly, in 2015, Lapua will produce 8x57mm JS brass. That’s good news for fans of this classic Mauser cartridge.
300 AAC Blackout Brass
Lapua’s Press release states: “Few cartridges have generated as much immediate interest as the 300 Blackout. Standardized by AAC, this diminutive cartridge is derived from the 223 Remington. Intended specifically for use in suppressed firearms, the versatility of the Blackout has appealed to a much broader range of shooters than just the audience for which it was originally designed. [Originally] intended to drive 220 grain bullets at subsonic velocities, the switch to lightweight bullets such as the 125 grain offerings delivers performance very similar to the venerable 7.62×39 cartridge. This makes the 300 Blackout potent enough for a wide range of shooting tasks, from certain tactical applications to many short range hunting situations involving medium-sized game. The ability for many 5.56mm/223 systems to be switched over to the 300 Blackout, merely by changing barrels, makes this an incredibly versatile combination. Lapua brings over nine decades of case manufacturing knowledge, precision and quality to the new Blackout, assuring the shooter of the very best performance.”
7mm-08 Remington Brass
Lapua notes that it’s new 7mm-08 brass is made to very high standards, benefiting hunters as well as competitors: “The 7mm-08 came to dominate the High Power Silhouette rifle game shortly after its introduction, offering a superb combination of power, light recoil and accuracy. Since then, it has also been used to win National Championships in High Power competition, and become a staple for hunters as well. With ballistic performance exceeding that of the time honored 7x57mm Mauser, but suited to a shorter action, the 7mm-08 is an ideal cartridge for most big game hunting. Lapua brings… state-of-the-art manufacturing methods, combined with old world craftsmanship, to the production of these cases. Primer pockets and flash holes are held to strict tolerances to withstand repeated firings and reloadings. After final necking of the case, they are finished with the proper anneal [for] accuracy and durability.” Lapua also notes that it offers two new 7mm Scenar bullets, which will work very well in the new 7mm-08 cartridge brass.
8x57mm JS Brass
Last but not least, Lapua is producing 8x57mm JS brass. Lapua notes that: “When the 8x57mm JS cartridge was introduced in 1905, its innovative use of a high velocity and relatively light weight pointed bullet design revolutionized infantry combat. An outgrowth on the original 8x57J military round, the 8x57mm JS round served the German military in both world wars, and became a popular sporting cartridge in any area where there was a strong German influence. From African plains game to European stag and boar, the 8mm Mauser has earned an enviable reputation as a big game round in a wide array of conditions. Accurate, versatile and powerful, the 8x57mm JS still serves the sporting community well for a host of hunting applications. In answer to the requests of the many devotees of this fine cartridge, Lapua is pleased to announce our introduction of the new 8x57mmJS case. The new 8x57mmJS will deliver the same accurate, reliable performance for which Lapua cases are world renowned. This means tough, durable cases that will not only withstand repeated loadings, but retain their accuracy shot after shot. [Lapua’s 8x57mm JS brass offers] very tight tolerances in neck wall concentricity and overall uniformity.”

Many shooters, particular those who shoot vintage military rifle matches, reload once-fired military cartridge brass. This brass may be high-quality and stout, but you may encounter a primer crimp* that interferes with the seating of a new primer. There are a variety of dedicated, military-crimp tools on the market, such as Dillon’s excellent Super Swage 600 tool that “rolls the crimp away”. But the Dillon tool costs $100.95 and takes quite a bit of room on your reloading bench. If you don’t want to drop a C-note and give up valuable bench space — here’s another (much cheaper) solution.
If you already have a Wilson case trimmer set-up, you can ream away those military crimps using an affordable Wilson accessory — the Primer Pocket Reamer (large #PPR-210, small #PPR-175). This $32.99 accessory is used in conjunction with a Wilson case trimmer and case-holder as shown below.
In the older Riflemans Journal website, the Editor, “GS Arizona”, shows how to use the Wilson primer pocket reamer to remove military crimps on Lake City .30-06 cartridge brass. He explains: “The case goes into the Wilson case-holder, the same one used for case trimming, and the reamer replaces the trimmer head in the tool base. The threaded rod on the left side, which is normally used to regulate trim length has no use for this operation and it is simply backed out. Hold the case-holder as you turn the reamer into the primer pocket, it cuts easily and quickly. The reamer will stop cutting when the proper depth is reached.”
Do you really need to do this operation with military-crimped brass? Yes, and here’s why: “any attempt to prime the case without removing the crimp will simply result in a mangled primer that cannot be expected to fire and certainly won’t fire reliably.”
*Why does military brass has a primer crimp? GS Arizona answers: “The crimp is nothing more than an intentional deformation of the case around the primer pocket, the purpose of which is to retain the primer in the case despite high pressure situations in machine guns and other automatic weapons where a loose primer may cause a malfunction. As reloaders, our task is to get rid of the remnants of the crimp in order to allow re-priming the case.”

Do you shoot a .308 Winchester (and who doesn’t)? Well here’s a great deal on Lapua .308 Win brass, the best you can buy. Ultra-consistent, Lapua brass stays strong for many reloading cycles, even with stout loads. Lapua is the choice of most F-TR competitors who shoot the .308 Win in competition.
The .308 Win Palma version brass (item BL11071) features small primer pockets. Some people believe the small primer pockets help the cases deliver a lower Extreme Spread (ES) and (maybe) withstand high pressures for more loading cycles. YMMV, but we do like the small-primer-pocket .308 Win Lapua brass and it’s our first choice for target applications.
Both types of Lapua .308 Winchester brass are now available at very attractive prices from Bullets.com: $61.95 for large primer pocket brass, $69.95 for small pocket brass. This cartridge brass is in stock today and ready to ship. CLICK HERE to order.
10/1/2014 Update: Sale Inventories of the Small Primer Pocket .308 Win Palma brass are sold out. You can still buy this brass, but the regular price is $79.95 per 100 cases.

The folks at PMA Tool, makers of arbor presses, neck-turning tools, and other case-prep tools, offer some good advice about case trimming on the PMA Tool Blog. Here we reprint a PMA blog post that explains case trimming basics and helps you choose the right case-trimming tool for your needs.
Case Trimming Basics
Trimming the cartridge case to the proper length is a crucial step in case preparation that should not be overlooked or underestimated. The cartridge case or the rifle can be damaged, or even worse you get badly injured. In most instances cases should be trimmed after firing and sizing. Trimming new brass is necessary for a lot of wildcats and can be beneficial in some instances, but by and large, trimming new brass is not necessary for most situations (unless you are neck-turning). Cases should be trimmed after you have sized the case, because the expander ball on the decapping pin can (and will) stretch the neck. Those of us who neck size should get into the habit of trimming after sizing as well. This is a good rule of thumb to go by, and hopefully it will keep you safe during the reloading and shooting process.
There are so many case trimmers out there that work, deciding which one is right for you can be confusing. Even though I have trimmed thousands of cases, using about every method possible, I can’t answer the question of what case trimmer is right for you because of all the variables that may be involved. I can, however shed some light on the subject.
The two most popular designs of trimmers either index (1) off the base or the head of the case, (2) off the shoulder or datum line of the case. There are pros and cons to each and it all depends on what you are willing to live with.
Indexing off the Base (Case Head)
Let’s talk about the first one I have listed, indexing off the base, or the head of the case. The pros to this method are that you can achieve a very accurate over all length and that is after all, what it is all about. The cons to this method are that you can get some variation doing it this way. Let me explain, the base is not always square to the body or can be damaged during firing especially if it is fired through a military style rifle with a very aggressive ejector. These cases should be discarded, but sometimes they can be overlooked. This condition can lead to an over all length that is incorrect. The case head being out of square will be corrected upon firing, however that case will wind up being shorter than the rest of your cases, possibly creating a difference in the neck tension on the bullet. The more you can do to eliminate variables in your reloads the better off you are going to be. This method can also be very slow, and if the user gets careless the result will be a inconsistent over all length.
Indexing off the Shoulder (Datum Line)
The second method I mentioned, trimming off the shoulder or the datum line of the case, has its pros as well. I have found this to be the quickest of the methods and very accurate as well. After the case has been sized through the die the dimensions (particularly the headspace) of the cases are usually very uniform and exact, this allows the case to be trimmed by indexing off the shoulder. This method can be done very quickly, by hand, or by powering either the case, or the trimmer. You also don’t have to worry about the case heads being out of square with the body using this method. Generally the trimming time is cut in half, and this leads to greater focus on the job, without becoming careless. [Editor’s Note: The World’s Finest Trimmer (WFT) is one power device that indexes off the shoulder datum. It works fast and is very precise. The new WFT 2 Model with interchangeable trim chambers works with multiple cartridge types.]
Summary
The choice is yours to make. I hope that this was some help to you, whether you are looking for your first trimmer or looking to replace the trimmer you have. Just remember to always put safety first and accuracy second, and you will start making little bug holes in no time.
