[QUOTE="SMK1000plus, post: 1609976, member: 93846"] If you do decide to just polish the chamber... I use a new brass case in the appropriate cartridge. I drill out the primer pocket and tap it with a 10-32 thread. Be sure it is drilled and tapped centered! I cut the case off just as the shoulder starts to roll away from the body, to ensure that I don't open the case neck or throat area, or change the chamber's headspace. Leave just enough shoulder to ease insertion into the chamber. Screw in a 18" 10-32 threaded rod with a locknut and lock the case to the rod. I also use loctite. If the opening in the case mouth is large enough, I install a lock nut inside the case as well. I chuck the rod and case assembly in a low speed portable drill and coat the brass with JB Compound. It is non-embedding and fairly mild. Polish the chamber for about 10 minutes then clean it and visually check your progress. Repeat until the chamber looks smooth. You may need to make a second or even a third polish case to replace the worn one as you go. When the chamber looks good, verify with a range trip. Repeat process as necessary until your spent brass comes out of the chamber smooth and extracts easily... [/QUOTE]
