I have a Savage Model 110 E. 30-06

My uncle gave me this gun last year. He gave me various reload rounds. 165's and 180 mags. They were shooting a bit wild. With in 3 - 4 inches at 100 yards on a gun rest.

I figured it was the reloads. So I bought some Federal shure shok 165 sprg. soft points. Still the same results. I know I can buy 150 and 180s.

Any thoughts?
