RE: Aluminum bullet cassings
shot those brass cased blazer 45 acp's today, guess what.... They are centerfire and totally reloadable. they are in my next batch of brass to be tumbled I will soon find out how they do as reloaded ammo. My guess would be the CCI brass cases are speer cases with a CCI headstamp.
They were very clean burning and were also very inexpensive, asfar as factory pistol ammo goes im gonna continue to buy these.
