Yes the case of Blazer .45 I shot up was horrendous. And I threw away about a dozen or 15 rounds from the case that were deeply inset. OTOH the last 500 rounds of plain old Remington UMC .45 ball from the Walmart 250 round value packs have shot lights out; shooting into 2" at 25 yards from a 1911. I didn't expect that.
