[QUOTE="J E Custom, post: 1704625, member: 2736"] I have encountered this many times. (Muzzle brake bore to small) and was making contact with the bullet. This is a very bad for accuracy and the brake it's self. This is one of those times that you want the correct size threads for strength to prevent damage to the rifle or a bystander. I recently had a brake that the bore was undersized after shooting gas check bullets. The gas checks came loose and lodged in the brake bore and the next round went through it, leaving a copper ring in the brake baffle. And in the process, that round left the ring in the second baffle. When this whole process finished all of the ports ended up with a copper ring in every baffle the bore of the brake. after the brake was removed, the barrel and crown was undamaged and the threads had done there job and didn't need re done. The brake was however done and had to be replaced. wanting to know more, I machined the copper out of the first baffle until it was all gone using a strong solvent and it had bonded/welded to the baffle and ended up almost .030 larger than the bullet diameter, so it appeared that the brake had been correctly bored .020 over. I have never seen carbon build up this bad, but normally proper cleaning will prevent this. and if the brake has/needs to be removed to make sure it is clean, it is ok to do so.
