I've decided instead of buying one, i'm gona build it from scratch. This won't be a target gun, just a plinker. I've been having problems finding an action. Mcmillian and Bat both have one for over $2k. Any other company's making action specifically for the 50 Bmg? I don't mind spending the money, just want to see all my choices. Single shot version is more than good enough for me.
