A few of those groups are decent for factory ammo. Pass three shots depending on the barrel steel and heat shots can start walking. When you go to shoot a critter you'll have a cold bore. My Rem 760 06 and Win 94 30-30 will start walking after three shots will darn near max loads slightly on the third shot. Sometimes it can be a rare sporter barrel that wont walk after getting warm. Are you shooting pre-fouled. A lot of that factory ammo also doesn't have the highest BC's in bullet application either subject to the wind. There's a lot of issues getting below 1 MOA with guns at the range like bedding, sun on target, target type, the day of the individual shooter, plus other issues. Reloading your own usually helps a lot. Any way with the 06, so what if your off 2" at a couple of hundred yards it don't mind.
