Lapua .308 Win Brass on Sale at Bullets.com

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.

Lapua .308 Win Brass

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.

Sinclair Product Report: Thumler’s Tumbler with Stainless Media

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.

I used it for the first time just before the National Matches on some .308 Winchester brass. I just added water and some Simple Green All-Purpose Cleaner and tumbled them for about 45 to 60 minutes. Wow! I have never had cases so clean both inside and out. The tumbler I used was the sample from our photo studio, and someone had left a 223 Remington case in there that was completely tarnished dark green. I left it in to see what would happen, and it came out just as clean as my .308 cases.

A lot of customers, and a couple of our techs, have told me about the good results they get with this tumbler, but I was still very impressed. At Camp Perry, I talked to a few shooters who had used it, and they all had only good things to say about the Thumler system. Of course, being shooters, they all had their own concoctions (recipes) of various cleaners. All I can say is that the Simple Green worked well for me. If you want to try something different for cleaning brass, you might want to give the Thumler system a tryout. The great thing about the stainless steel media is that it never wears out. Buy it once and never buy media again. We sell a kit of the Tumbler and 5 lbs. of media that will save you a few bucks off buying them separately.” — Bill Gravatt

Tips on Case-Trimming from PMA Tool

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.

Wilson Micrometer Case Trimmer

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.

Forster Case Trimmer

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.]

Little Crow WFT

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.

How Cartridge Brass is Made — The Inside Scoop

When we first ran this story a while back, it generated great interest among readers. By popular request, we’re reprinting this story, in case you missed it the first time around. — Editor

Rifle cartridge brass manufacturingPrecision shooters favor premium brass from Lapua, Norma, or RWS. (Lake City also makes quality brass in military calibers.) Premium brass delivers better accuracy, more consistent velocities, and longer life. Shooters understand the importance of good brass, but many of us have no idea how cartridge cases are actually made. Here’s how it’s done.

The process starts with a brass disk stamped from strips of metal. Then, through a series of stages, the brass is extruded or drawn into a cylindrical shape. In the extrusion process the brass is squeezed through a die under tremendous pressure. This is repeated two or three times typically. In the more traditional “draw” process, the case is progressively stretched longer, in 3 to 5 stages, using a series of high-pressure rams forcing the brass into a form die. While extrusion may be more common today, RWS, which makes some of the most uniform brass in the world, still uses the draw process: “It starts with cup drawing after the bands have been punched out. RWS cases are drawn in three ‘stages’ and after each draw they are annealed, pickled, rinsed and subjected to further quality improvement measures. This achieves specific hardening of the brass cases and increases their resistance to extraordinary stresses.” FYI, Lapua also uses a traditional draw process to manufacture most of its cartridge brass (although Lapua employs some proprietary steps that are different from RWS’s methods).

RWS Brass Cartridge Draw process

After the cases are extruded or drawn to max length, the cases are trimmed and the neck/shoulder are formed. Then the extractor groove (on rimless cases) is formed or machined, and the primer pocket is created in the base. One way to form the primer pocket is to use a hardened steel plug called a “bunter”. In the photos below you see the stages for forming a 20mm cannon case (courtesy OldAmmo.com), along with bunters used for Lake City rifle brass. This illustrates the draw process (as opposed to extrusion). The process of draw-forming rifle brass is that same as for this 20mm shell, just on a smaller scale.

20mm cartridge brass forming

20mm Draw Set Oldammo.com

River Valley Ordnance explains: “When a case is being made, it is drawn to its final draw length, with the diameter being slightly smaller than needed. At this point in its life, the head of the draw is slightly rounded, and there are no provisions for a primer. So the final drawn cases are trimmed to length, then run into the head bunter. A punch, ground to the intended contours for the inside of the case, pushes the draw into a cylindrical die and holds it in place while another punch rams into the case from the other end, mashing the bottom flat. That secondary ram holds the headstamp bunter punch.

Lake City Brass bunter

The headstamp bunter punch has a protrusion on the end to make the primer pocket, and has raised lettering around the face to form the headstamp writing. This is, of course, all a mirror image of the finished case head. Small cases, such as 5.56×45, can be headed with a single strike. Larger cases, like 7.62×51 and 50 BMG, need to be struck once to form a dent for the primer pocket, then a second strike to finish the pocket, flatten the head, and imprint the writing. This second strike works the brass to harden it so it will support the pressure of firing.”

Incipient Case-Head Separation — How to Detect the Problem

Here’s an article from a couple seasons back. For safety reasons, we are republishing the story. Recently, one of our contributing writers experienced a similar problem at the range. Here, German Salazar looks at the causes for case-head separation, and he recommends a procedure for inspecting your cases.

cartridge case separationOn his Riflemans’ Journal blog, German Salazar wrote an excellent article about cartridge Case-Head Separation. We strongly recommend that you read this article. German examines the causes of this serious problem and he explains the ways you can inspect your brass to minimize the risk of a case-head separation. As cases get fired multiple times and then resized during reloading, the cases can stretch. Typically, there is a point in the lower section of the case where the case-walls thin out. This is your “danger zone” and you need to watch for tell-tale signs of weakening.

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

cartridge case separation

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

Trim-It Case Trimmer Features Micrometer Cut-Length Control

This new tool trims cases quickly, with precision control over case length via a micrometer-type dial. The folks at ACT Tactical have developed an easy-to-use compact case trimmer called the TRIM-IT. Crafted from 6061-T6 aluminum, this sturdy case trimmer comes with a 100% lifetime guarantee. The $97.50 TRIM-IT features a micrometer that’s built into the unit itself. Caliber-specific inserts (called “Caliber Dies”) index off the case shoulder.

Trim-it Case Trimmer Micrometer Cartridge Brass

The TRIM-IT can work with any hand-drill or drill press. Once you get the hang of it, you can trim a case in 7-8 seconds — that gives you a production rate of 400+ cases per hour. The TRIM-IT delivers repeatable precision to plus/minus one-thousandth. This unit also holds its cut-length setting, unlike some other trimmers which require frequent adjustment.

Trim-it Case Trimmer Micrometer Cartridge Brass

The basic unit ships with two caliber dies, for .223 and .308. Other listed caliber dies include 6.8 SPC, .300 BLK, .30-06, 30-30 Win, 300 Win Mag, 7MM REM, 7.62x54R, and 8MM Mauser. Other cartridge types can be custom-ordered from EZTrimit.com. To change dies, simply loosen the set screw on the TRIM-IT, take the caliber die out, add another one, and tighten the screw — quick and easy.

The built-in micrometer is great. The handy dial gives you a positive, repeatable length setting quickly — no fiddling with locking rings or spacers. Once you get the ring set properly, the cut lengths are consistent from the first case to the last. Expect your case OAL spread to be about +/- .001″ (starting with full-length-sized cases with uniform rim to shoulder lengths). For more information, email sales [at] eztrimit.com or call (562) 602-0080. You can see how the Trim-It device works in the video below.

Defining “Overbore” Cartridges via Comparative Index

What is “Overbore”? That’s a question rifle shooters can debate to no end. This article from our archives proposes one way to identify “overbore cartridges”. We think the approach outlined here is quite useful, but we know that there are other ways to define cartridges with “overbore” properties. Whenever we run this article, it stimulates a healthy debate among our readers — and that is probably a good thing.

Forum Member John L. has been intrigued by the question of “overbore” cartridges. People generally agree that overbore designs can be “barrel burners”, but is there a way to predict barrel life based on how radically a case is “overbore”? John notes that there is no generally accepted definition of “overbore”. Based on analyses of a wide variety of cartridges, John hoped to create a comparative index to determine whether a cartridge is more or less “overbore”. This, in turn, might help us predict barrel life and maybe even predict the cartridge’s accuracy potential.

John tells us: “I have read countless discussions about overbore cartridges for years. There seemed to be some widely accepted, general rules of thumb as to what makes a case ‘overbore’. In the simplest terms, a very big case pushing a relatively small diameter bullet is acknowledged as the classic overbore design. But it’s not just large powder capacity that creates an overbore situation — it is the relationship between powder capacity and barrel bore diameter. Looking at those two factors, we can express the ‘Overbore Index’ as a mathematical formula — the case capacity in grains of water divided by the area (in square inches) of the bore cross-section. This gives us an Index which lets us compare various cartridge designs.”

OVERBORE INDEX Chart

Overbore Index Chart

So what do these numbers mean? John says: “My own conclusion from much reading and analysis is that cartridges with case volume to bore area ratio less than 900 are most likely easy on barrels and those greater than 1000 are hard on barrels.” John acknowledges, however, that these numbers are just for comparison purposes. One can’t simply use the Index number, by itself, to predict barrel life. For example, one cannot conclude that a 600 Index number cartridge will necessarily give twice the barrel life of a 1200 Index cartridge. However, John says, a lower index number “seems to be a good predictor of barrel life”.

John’s system, while not perfect, does give us a benchmark to compare various cartridge designs. If, for example, you’re trying to decide between a 6.5-284 and a 260 Remington, it makes sense to compare the “Overbore Index” number for both cartridges. Then, of course, you have to consider other factors such as powder type, pressure, velocity, bullet weight, and barrel hardness.

Overbore Cases and Accuracy
Barrel life may not be the only thing predicted by the ratio of powder capacity to bore cross-section area. John thinks that if we look at our most accurate cartridges, such as the 6 PPC, and 30 BR, there’s some indication that lower Index numbers are associated with greater inherent accuracy. This is only a theory. John notes: “While I do not have the facilities to validate the hypothesis that the case capacity to bore area ratio is a good predictor of accuracy — along with other well-known factors — it seems to be one important factor.”

Official 26 Nosler SAAMI Drawing Now Available

26 Nosler Cartridge Print SammiNosler has introduced a new 6.5mm (.264 caliber) hunting cartridge, the 26 Nosler. Nosler will initially offer 26 Nosler cartridge brass, and then, eventually, 26 Nosler loaded ammunition.

This new cartridge is designed to be a speedy, flat-shooting hunting cartridge, with performance exceeding a 6.5-284. This is possible because the 26 Nosler is a big, long cartridge with plenty of “boiler room”. Length from base to neck/shoulder junction is 2.33″ for the 26 Nosler, compared to 1.91″ for the 6.5-284 (and 2.04″ for a 7mm Rem Magnum). The 26 Nosler has a 35° shoulder angle and a magnum-size 0.534″ outside rim diameter.

The 26 Nosler cartridge can drive the Nosler 129 grain, AccuBond® LR bullet at 3400 fps. Zeroed at 350 yards, the 26 Nosler has a Point Blank Range of 0-415 yards. Loaded with the 129gr Accubond, the 26 Nosler retains as much velocity at 400 yards as a .260 Rem produces at the muzzle. This makes the 26 Nosler a “quintessential deer, antelope and long-range” cartridge according to company CEO/President Bob Nosler.

Nosler has just released the SAMMI print for this cartridge. CLICK HERE for SAMMI Print PDF.

Tips for Reclaiming .223 Rem Range Brass

Bryce Towsley has authored an informative article on Reclaiming .223 Rem Brass. Writing for Shooting Illustrated Online, Towsley confesses: “I’m a brass horder…. I end every shooting match on my hands and knees. If the rest of the competitors want to litter the range with their discarded cases, I see it as my civic duty to clean up the mess.” If you burn through a lot of .223 Rem ammo on the varmint fields or in multi-gun matches, we suggest you read Towsley’s article.

Towsley advises that you need to be cautious with range pick-up brass: “Range brass is full of dirt, dust, sand and debris that can be damaging to loading dies, as well as causing other problems.” So, range pick-up brass must be cleaned and then sorted carefully. Towsley explains that you should toss brass that is badly dented, and you have to make sure to remove the primer pocket crimp in military brass. This can be done with a crimp reamer or a swaging tool such as the Dillon Super Swage 600. The latter works well, but Towsley cautions: “For the swager to work properly, you must sort the cases by brand and lot, and then readjust the swager for each new lot.”

Trimming Quantities of Brass
Before loading, “reclaimed” range brass should, of course, be full-length sized and you should trim all the brass to the same length. “Cases that are too long can cause all kinds of problems”, explains Towsley.

We envy the system Towsley uses to trim brass. He has a Dillon Rapid Trim 1200B set up on the top of a single-stage press: “You simply insert a case into the shell holder and raise the ram to trim it instantly. The process is so fast, it almost feels like cheating.” The Rapid Trim is a very neat gadget — it even has an attachment for a vacuum hose to remove the cuttings. The photo at right shows a 1200B installed on a Dillon progressive press.

We definitely recommend you read Bryce Towsley’s Reclaiming Range Brass Article from start to finish. The article offers useful advice that will help you reload any rifle cartridge — not just .223 Rem range brass. Towsley also showcases many good labor-saving devices that can speed up and simplify the process of bulk rifle cartridge reloading.

Norma Offers Seven New Types of Cartridge Brass for 2014

Norma cartridge brass 6.5 7mm 300 blackoutNorma is making a big push to expand its presence in the North American market. As part of this effort, Norma is introducing seven (7) new types of cartridge brass for 2014. We’re pleased to report that Norma-USA will be importing top-quality brass for the 6.5 Grendel, and 6.5 Creedmoor, two popular target cartridges. In addition, for 2014, Norma will offer 7mm RUM, 7mm Blaser Magnum, 300 AAC Blackout (300 BLK), .300 RUM, and the .338 Blaser Mag. The Norma brass we have shot in other chamberings (6 PPC, 6mmBR Norma, 6XC, .243, 7mm RSAUM) has all been excellent, giving good accuracy. Case weights were very consistent and the neck-wall thickness was very uniform, particularly with the PPC and BR brass. The new 300 BLK brass is an important offering for AR shooters. (NOTE: You can also make 300 BLK cases from Norma or Lapua .221 Fireball brass).

Though the annealing “shadow” may not be as visible as with Lapua brass, the case necks of Norma brass cartridges are indeed annealed near the end of the manufacturing process. This assures more consistent neck tension — something critical to accuracy. Most of the new cartridge brass offerings should be be available at vendors by early April, 2014. You can get Norma brass from Bullets.com, Grafs.com and Midsouth Shooters Supply, as well as many other online vendors.

New Norma-USA Brass Offerings for 2014:

  • 6.5 Grendel
  • 6.5 Creedmoor
  • 7mm RUM
  • 7mm Blaser Magnum
  • 300 AAC Blackout (300 BLK)
  • .300 RUM
  • .338 Blaser Magnum

Precision Jig for Neck Chamfer Tool

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).
