I'm going to loading for a BM 24" heavy fluted match barrel. I've had good results for my .308 bolt with LC brass & Sierra MK bullets. I want to make this AR15 all it can be! Any advice on brass, powder, bullets, etc. would be helpful. This is primarily going to be a long distance weapon and I don't have a lot of experiance with heavy bullets (55 gr.+)
in .223. Any advice on what 'long distance' for this weapon is realistic would also be appreciated. Thanks!
