It's not right to extrapolate from one rifle to an entire model of rifle in every other caliber, especially when the experience is with some oddball, hard-kicking specialty rifle.
A lightweight carbine firing a 270-grain bullet at 2600+ fps is going to be a challenge for a human to shoot small groups, whatever its locked down inherent accuracy may be.
All my .375 H&Hs have been really accurate, but they all had 23 to 25 inch barrels, and weighed at least 9 lbs with iron sights.
