I've watched people shoot semiautos at 200 and 300 yards with the typical bulk 5.56 and 7.62 fmj and the groups weren't pretty.
I did a favor for a friend of a friend and mounted a scope on a new Rem 700 VTR in 308, and also did a prelim sight in with a couple of varieties of 147 fmj that had been supplied with the rifle and scope. The groups were bad enough that I thought there could be a rifle problem, a scope problem, or both.
I couldn't let it go at that, so I went home and used the brass to make up an old school M1A 168 grain match load with 3031. Voila, .75 moa five shot groups.
