Well, if that don't burn the monkeys a$$. All my TZZ was, um, ah, aquired from military ranges and the pockets aren't crimped. Easiest way to remove the crimp is with a Dillon Super Swage. I use it for 5.56 brass. Not worth the $ if you don't use it fairly regularly, though. Hey, you could send me the brass!We now own a 1000 rounds of TZZ brass with crimped primer pockets!
