I bought 500 pieces of .308 LC brass for my 24" 308 I plan on shooting out to 1000yrds. So far, I've had much better luck with commercial brass than with the military stuff. I bought the mil brass because I thought it would be better in the long term since it's thicker and presumably more durable. I'm on a budget and can't afford a bunch of lapua brass so I'd like to figure out how to make this mil brass work. I have yet to try fire-formed brass and still have some research to do on the matter.

Is it even worth wasting my time with this brass? What can I do to shoot tighter groups with it? I'm currently loading 175 SMKs and 178 A-Max bullets over IMR4320 using an RCBS depriming/resizing die in a Lee beginner kit.

Thanks!
