Remove Military Primer Crimp with Wilson Primer Pocket Reamer

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 $32.00 accessory is used in conjunction with a Wilson case trimmer and case-holder as shown below.

German 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. German cautions: “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? German 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.”

MidwayUSA Pro Series Competition Shooting Mat for $49.99

The MidwayUSA Pro Series Competition Shooting Mat is now on sale for just $49.99, through the end of March, 2013. That’s 51% off the regular $102.99 price. This mat is bigger and better than MidwayUSA’s original shooting mat, with many enhancements. The Pro Series mat measures a full 73.5″ x 35.5″ and the padding is thicker. There is a zippered pocket on the front extension flap to hold ammo or log book. The rubberized contact areas are tan now (rather than black) so they don’t get so hot in the sun. And the designers added webbing “pockets” for bipod feet so you can pre-load the ‘pod with forward pressure. MidwayUSA has done a good job improving a mat that was already a good deal for the money. At $49.99 on sale (through 3/31/2013), this Pro Series mat is a great deal.

MidwayUSA Buyer Reviews:

Five Stars: Great upgrades to the original. It’s bigger in every direction, and the padding is twice as thick. The new knee and elbow pads won’t get as hot as the black material on the old one did, and the new material is “grippier” than the old stuff too. The bi-pod stop is a nice touch if you shoot F-T/R. — Bob M., Missouri, 10/6/2010.

Five Stars: As a competitive shooter my mat is important. The mat I replaced had been with me for about twenty years. It had been with me through the famous weather at Camp Perry, the winds and sand of Grayling 1000 yard matches. My Midway mat arrived shiny and new, full of stuffing, stiff and green. At my next match I found I liked the feel of the mat, it has handles! The rocks and sand on the firing line were not as sharp. The rubber is well-placed. It has proven to be rugged and quite up to the task. I am seeing more Midway mats at matches. A good thing. — Tom, Michigan, 12/26/2012.

Four Stars: I purchased this mat for a 2-day Appleseed event this fall. Good overall quality and more than wide and long enough for my frame. The only drawback and reason for me giving it 4 stars instead of 5 is that the padding is insufficient when placed on top of a rocky surface. I wasn’t looking for a sleeping mat mind you, but you feel every single rock underneath the mat when shooting prone (especially on the elbows), kneeling and when transitioning between positions. Best to use another pad underneath if you are using it on a rocky surface. Most of the other mats out there have the same drawbacks so this is still a great choice at a very decent price. — Chris S., Illinois, 1/6/2013.

Five Stars: This is a great mat for the money. It’s larger, thicker, and stickier than my old one. I could use larger knee area friction pads, but that’s the only complaint. The elbow area is huge and that’s what’s best. Much cooler in the sun, too. Rolls up and rolls out easy. The double-adjustable carry strap has built in loops I use for carrying a rolled up foul weather cover. The fold-out front fly is large and useful. This is a good looking, hard working mat. — Steve R., Illinois, 10/11/2010
