I've got a new 7prc build and after a few shots to zero and another 12 shots trying different factory loads I have a 5 shot 1/2" group from the Fed Terminal Ascent 170gr. This is a Hart barrel and their recommended break in procedure is a little confusing. When should I clean this barrel so I don't screw anything up while it's setting in? Thanks in advance!
