Jparker29... scoped or open sights? What distance? Bore clean? All things being equal would the rounds be so far apart as that? Maybe, but does not seem likely unless the barrel is worn out. Scope loose? My weapons like certain ammo better than others but they tend to group together. Its just that some hit where I aim and some others don't. They hit elsewhere but they tend to group together. I think the best ammo for your hunt will be the round you can group under two inches at 100 yards. My old Winchester model 70 sears and roebuck '06 puts three rounds under a dime at 100 yards for me.
