I have read a lot about deep cleaning a shotgun on this and other web sites, and recently cleaned my relatively new Moss 535. The procedure i used was from the allaboutshooting website. It seemed like a pretty quick and easy procedure, so it has left me thinking that maybe i am missing something. Does deep cleaning mean POLISHING your barrel also? The polishing procedure as detailed in this web site looks very involved! I know it certainly wouldn't hurt anything to polish a barrel (unless i made a mistake with the drill), but do most of you guys polish to get fantastic patterns?
