[QUOTE="Painless300, post: 2194098, member: 115546"] My regiment on a new barrel is always clean before the first shot to make sure all cutting oil and debris is removed. Then load up 50 rounds at minimum book loads. Remove ejection plunger to fire form all brass. Shoot 1 and clean, shoot 5 and clean, shoot 10 and clean. Shoot the remaining 34 rounds then clean. I always run my magneto speed to monitor speed. I will then load up another 20 rounds and run a pressure test, again over magneto speed and record all MV's. I will usually start my load work up and by the end the barrel is pretty much broken in. 100 - 150 rounds. [/QUOTE]
