You are on the right track, but that particular rifle is probably not capable of much better. Your reloading process could become very precise and by the results that rifle would give you, you would never know it. The cost might seem unsound, but you would better off with a know proven 1/2 MOA rifle that did not have a sporter stock. It seems that every random shooter has a rifle that shoots 1/2 MOA. Meet a shooter with a 223 bolt gun at the range and when he shoots a 1/2 MOA or less 5 shot group, buy his rifle. I’m saying this as a guy with $10’s K into the shooting sports, much of it unnecessary because no one told me this stuff beforehand.
