that's kinda why I wanted to try some other ammo first before I did anything else, I've shot quite a bit of Magtech over the years and never had any trouble so maybe I just got a hold of a bad lot or something, A guy suggested earlier that I call Magtech and check the lot number with them. I bought about 5 boxes of the stuff at a store that was closing here in OKC about 2 months ago so I can't take it back now!
