For range ammo.

I have never used Armscor 45acp.  But I really like Armscor 9mm and 223.  I have never had any issues with it.

Shot off a box of 50 the other day with no issues. It is the cheap ammo the local shop is pushing and I haven't heard any complaints up there.

I have not used their .45 ACP ammo, but had barrel blown by a 9mm squib of theirs. Did the warranty thing, they asked for the gun, a Glock 17,  to be shipped to them. Later they informed me they were going to destroy the gun and give me $500 for it, claiming they could not fix the gun as they were not set up for Glocks. All it needed was a new barrel, $150 cost item. I threatened them with legal action if they did not return the gun, got the gun back. Replaced the barrel, gun works fine. In any case, be wary of their products and of their warranty.
