I have a 308 Rem AAC that I was about ready to wrap around the nearest tree. I have tried numerous loads/primers/bullets/etc I was using trail boss exclusively at first until I got some great advice on this site. Someone on here suggested International Clays powder. I tried it with 3 different bullets and all of my first 3 shot groups were less than one MOA. In fact, the Hornady 180 RN were under 1/2 moa. Can't wait to get it back out.
