This guy will also make any semi auto shoot. My first center fire in 1980 was a Rem 742 semi-auto chambered in 30-06. I was lucky to get a 5" group out of it at 100 yds. At the time I was coming out of the military, and my opinion of semi auto's was really poor. I started reloading at the time because "those that know all" said I could tune the gun with some reloads. I got it down to a 3" group, but thats not good enough. Prior to that I had LOTS of experience with the M-16A1. It really sucked to have to stop in the middle of a fire fight to clear a jam and clean it so it would shoot again.
