The other day I was running some relatively recently bought Speer Blazer Brass 45 acp 230 gr. FMJ RN through my Tisas Tank Commander as I was breaking her in. Back at home I was separating makes of brass to reload and realized that the Blazer Brass was primed with small pistol primers. Have heard of that but never ran across any. Not a big deal for non-reloaders but for those of us who reload it's something to watch out for. May want to open the box for inspection before buying. I'm now trying to figure out how to prime the things as everything I have to prime 45 acp is set up for large pistol primers.
