What up guys. I'm new to the forum. I also just picked up the Big Rock a few days ago. Took it to the range and fired some sig sauer fmj rounds through it (all buds had at the time for range). It didn't place nice with them. Out of the 50 I shot 6 wouldn't fire. Hoping it was just a bad box. Anyway I'm grabbing some small orders from Georgia ammunition to try out. Anyone tried their 10mm yet?
