I've bought some of their .45acp, all went BANG just fine. I think it *might* be remanufactured ammo, not sure, it was a few years ago. But it seems like it was all mixed headstamp brass. Didn't buy any more because I just don't like to mail order ammo, and this was when WalMart had piles of WWB for $29.98/100. Our local store had so much .45 & 9mm, they had to set up a table in the aisle to put it all on.
Plus, I reload now anyway.

I have found Armscor's .223 as about average - better than surplus, less than good Remington or Federal commercial.
Their rimfire ammo sucks though - tried some "Armscor Precision" target .22LR once - wasted good money. Shot worse than Remington Golden Turds, and that's as bad as it gets!
