Hi
You should read the stickies at the top of this forum there's lots of good info/advice there.
Here's a quote from a post by quickdtoo about chamber polishing:
Quote:
Aside from keeping the chamber clean and dry, you can polish the chamber with a bore mop wrapped with a patch and some JB Bore compound or Flitz metal polish. Add the tip section of a 3 piece cleaning rod chucked in a drill and polish for a minute or two staying away from the throat and moving the mop in and out of the chamber so the polish job is even. Change the patch and add more polish a few times....works for me, have never had a stuck case that wasn't my fault for not wiping out the chamber before firing a round.
