[QUOTE="PNWdude67, post: 2193490, member: 110615"] Do what makes you feel good. There is no evidence that one way is better than another. My theory, no evidence to support, the lighter the contour the more excessive heat from high round count strings shot rapidly the more negative effect on the barrels performance do to irreparable damage. Break in for me consists of running a dry patch or two down the new barrel, firing some rounds, cleaning with carbon remover after 50 and firing 100 more. Then load 25 to check accuracy and velocity with the projectile and powder of choice with 5 charge weights expected to be near a known velocity node. If it’s all new to me, chamber bullet case etc, I do a ladder test to determine a starting point. Then clean about every 300 rounds for life of the barrel. If it needs to cool I stop shooting for a bit, works every time. [/QUOTE]
