[QUOTE="J E Custom, post: 701620, member: 2736"] Very good advice indeed +++++ The best finish for a chamber is the one that a good chamber reamer leaves. If it is a good reamer and it is cut correctly there are no marks,scratches, rings or chatter marks and the finish is smooth and almost shiny. Polishing a chamber is not recomended because if you remove scratches you have to remove metal and change the original dimensions even if only buy a 100th of a thousandth. also the cartrige/brass needs something to grip in order to keep from excessively loading the bolt lugs and abutments as Geargrinder stated. The best way to clean debris out of a chamber if to use the same reamer that cut the chamber and make one full turn by hand applying little or no pressure. Obviously this is hard to do if you dont have the original reamer but it is the best way.(Never use a different reamer because they are never exactly the same). All ways inspect the chamber with a good bore scope or make a cast of the chamber using Cerrosafe and then if nothing is there you don't risk ruining a perfectly good chamber. I recomend orienting the head stamp at 12;00 and firing the round then after extraction you can figure out if it is consistantly in the same spot. Sometimes it is striking something on ejection (Scope base, turret,back of reciever, Etc) so make sure that it is something in the chamber before even considering messing with the chamber. I have had to set back to many chambers that were polished wrong and caused problems afterwards. Just some advice for what it is worth. J E CUSTOM [/QUOTE]
