Thread: Thoughts on new barrel ' break-in '

Factory tikka have already had an accuracy test before they leave, so they have already had rounds down the tube. Clean it, send some rounds down range and enjoy it. Grouping from my tikka win mag tightens up after about 15 rounds from new ended up under a inch at 200m on factory ammo. Went home cleaned the shit out of it with copper solvent etc, went back to range took another 15 rounds to get it grouping again.
