I' m with Mauser06 on this one. except I would stae that a 4" group isn' t even necessary- an 8 inch group at 300 yards would be good enough provided you are consistant and base your group size on many more than the 3 shots you use to sight in a rifle a week before deer season. If you can keep 10 shots in a row within a pie plate at the maximum distance that you will be hunting at from an improvised position, you will do alright. Shooting a 1/2" 3 shot group at 100 yards really doesn' t mean much and isn' t even an accurate representation of the limitations of your rifle. Shooting from a bench means even less unless you are going to set up the same shooting bench at the edge of a field pointing at a bait pile at a known distance.
