[QUOTE="BountyHunter, post: 414320, member: 12"] Mikecr The wipeout, ME and others will take out the carbon if you use a hard bristle brush. Let them set and then scrub. I use Wipeout exclusively now for carbon and use a borescope also. Occasionally I might have to revert to a little ISSO or JB. If you have firecracking, then be very careful removing too much copper. It will lead to bullets catching on the edges of the holes and the mild firecracking quickly turning into "alligatoring" with big chunks missing. When that happens you are SOL and time to get a new barrel. We had a guy who kept getting bullet blow up on a 10 shot string with a new barrel and finally found an "occlusion" (hole) in the metal where it had been rifled and surfaced when a little material was worn off. Caught the bullets some and tore the surface slightly we think resulting in the blowup at the 50-100 yd mark when it got hot. So it does not take much As for the aftermarket barrels not coppering. Most of the mftrs have procedures to get the barrels as smooth as possible. Often double lapping. Even then they will tell you that have to cut off the last 1 to 1.5 inches of the blank at the breach and this is with "master" lappers. No one is going to equal that after it has been crowned. Even their best lappers will bell the muzzle crown and ruin the accuracy if not cut off and recrowned. BH [/QUOTE]
