I have a nice Remington 5R in 223 Timmeny trigger. From all Ive read it should be a sub MOA rifle. Ive tried a couple 55 grain load, Winchester and Federal, and the old 62 grain green tips and cant bet much below 1.5 moa. Ive checked the scope and dont think its the problem. It could just be that I cant shoot worth a damn but Im wondering if some match or lighter (40 gr...45gr...50gr?) ammo might make a difference.? I know try some but its not easy to find local. Anyone have any experience with this rifle?
