High Performance Rifle Barrel Cleaning

This is the cleaning method that I've converged on for cleaning high performance precision rifle barrels. It uses abrasive compound rather than traditional carbon/copper solvents. The benefit of this method is that in addition to removing fouling, it also smooths the barrel from fire cracking. High performance rifles that burn a lot of powder cause accelerated erosion in the breach end of the barrel. This erosion is accompanied by fire-cracking with increases friction and causes the following bad effects: 1) The roughness acts to increase the friction of the bullet going down the barrel. This increases the back-pressure on the powder burn, causing it to burn hotter/faster which elevates pressure and velocity, often outside the safe or desirable window. 2) Excessive barrel roughness in high performance rifles can result in bullets failing in flight. Cleaning with abrasives as prescribed in this video will keep your high performance rifle functioning in a consistent velocity window, as well as inoculate you from bullet failures.
