So I've had time to bang out several rounds of both the 38 Special and the 308s from USA Ammo. Looks like I either ended up lucky or USA Ammo stepped up their quality control. The 38 specials and the 308 Wins were not nearly as dirty as I thought they would be and most of them seemed pretty consistent, I couldnt tell the difference between factory and the USA Ammo stuff. The grouping with the FMJ 308s were no different from Winchester SuperX PowerPoint 150 grain 308s. Both from friend and I were getting 1 inch groups at 100 yards using slow fire from the bench with both brands.
So if you're willing to wait 3-4 weeks for remanufactured ammo, I suppose USA Ammo is alright, but I'd stll be cautious.
I'm already surrounded by half-dead brainless people already, the zombie apocalypse would just give me a reason to be productive and get rid of them.
