Nick shot 1 in my first target was cold bore shot. Didn't seem to shift hardly any from all the other shots.
It has about 30 rounds through it so I think I am going to give it a scrubbing this weekend.
I know everyone has their "magical" method to everything but Whidden told me with new barrels he shoots 20 rounds then scrubbs the heck out of it and does it this way for first 100 shots. Then after that he lets accuracy dictate when he cleans. Also told me to use JB bore paste or IOSSO every 150 rds to really clean carbon out
