Bought two bricks of this stuff a couple of years ago. Pulled a couple of boxes that summer, stored the rest in my fort. Shot one box out of an early 2000's Mk II. Had one case blow out at the rim. First time I'd had that happen in around 15k rounds of shooting 22. CCI, Federal, Winchester, Remington all good.
Decided to try another box of the Armscor yesterday. Using a different MK II this time, mid 90's vintage. Last mag out of the box resulted in this. 
Knew it as soon as I pulled the trigger. I can't find a photo of the first incidence, but it was the same as this one. I'm done with this stuff in my pistols. It will be blasting ammo for my 10/22's and lever guns. I consider two blown cases in 100 rounds bad stuff. Guess it wasn't such a good deal after all. Makes me question the quality of the Armscor 300 Blk and 10mm brass I've bought. |
