This question is not just for Ken,but others with more experience than I.I finally got my dies,the scope mounted,trigger cleaned,fixed,and adjusted,bolt and bore cleaned.The rifle is a unfired ' 68 L61R Sako .338 Win Mag.Time to load some and head to the range.I have read all sorts of things for barrel break-in,shoot one,clean one,5 X,etc.I am a bit odd,I am more interested in the why ,than the how.Like what are you doing by this cleaning?
