Thread: Breaking in a new barrel

The truth is probably somewhere in between. The bore is probably the smoother the better, but a few shots, a few cleans, or a few through of autosol is probably not going to fix any burs or machine marks. Lilja states that there is no need indeed serves no purpose to break in, this makes sense because lilja does hand lapping to all their barrels. my view is that all unless you do proper hand lapping, might as well dont do any breaking in. but if you had to spend the money for hand lapping kit, might as well buy a better rifle or at least better barrel in the first place.
