[QUOTE="Kennibear, post: 899690, member: 51650"] I have used Barnes' CR10 on a new factory cut rifling barrel that seems to foul pretty fast. I leave it in for about 15 minutes after applying with a nylon brush. It cleans the best of the products I have tried although I haven't tried them all. My custom E.R.Shaw is a button rifled barrel and the bore is characteristically smooth. It fouls less. Cold hammer forged barrels (using the H&K process) have a very smooth finish. Hand lapped barrels are the best finish possible. Your barrel does not seem out of the ordinary range of experience. Clean as needed. I would try a break in any how. Couldn't hurt. KB [/QUOTE]
