lol, take it easy on him guys. (Though I WAS wonderin how a barrel knows the difference? ) ALL guns will "take a set" after 3-4 boxes. Personally I think it's a matter of patience, don't get the gun hot. Shoot slowly and allow cooling between shots. BUT that's advice for ALL guns, regardless of their age. I also like to keep a BoreSnake or cleaning rod beside me while shooting, ESPECIALLY a new one. Later today I am gonna shoot my lil new 22/250 and I am gonna run the snake through it between each shot. No sense in impregnating dust and powder residue into a new bore. Just like clockwork, with every rifle I have they ALL woke up after that 3rd or 4th box (seems like the faster guns take fewer shots, make sense as those rounds are doing more "polishing" with each pass of a pill through the bore!) and I suspect no difference today with my lil Savage.

Good luck and take your time,
RA
