If the bullets are tumbleing it may fouling matainence.. But more than likely, his bullets are too hard...this was the cause of tumbeling in my 45-120.
This is most likely the case, because a soft(er) bullet will obturate..and they seem to be able to handle more fouling..
Anealing cases will sometimes cut a groups size in half or better....but that is not causing the tumble.

Mister, why do you carry a 45? "Cause Sam Colt don't make a 46."
