I have been looking for a good buy on a 1,000 round case of .45, 230gr. FMJ for a little over a week now. Today I found what I thought was a good deal. I got 1,000 rounds of CCI Blazer .45 230gr. FMJ for $270.00. When I get home, I realize that this stuff has Aluminum casings. I have never shot aluminum cased ammo before, but since I don’t reload, I don’t see any issues with using it. Any one have experience with aluminum cased ammo? Any concerns with shooting it in my Kimber .45’s?
