BORE SMOOTHING

Buy some JB Bore Compound or Iosso Bore cleaner. These are pastes, very mildly abrasive, designed to clean bores without harm. Put this paste on a patch that fits snugly and work it back and forth in the bore until the patch becomes a loose fit (usually six to 8 passes).
Do this at least a dozen times. This will remove factory preservatives and help smooth the bore somewhat.
If the chambers are rough, this may also be done but do so by hand. Resist the temptation to chuck your cleaning rod in a drill; you can too easily enlarge the chamber.
After the bore or chambers are smoothed, remove the paste with patches wet with Ronson lighter fluid. Lighter fluid evaporates without leaving behind deposits.
