Smoothing A Rough Bore

[Ninering62]

What color? Some are much more aggressive than others ...

WHITE- I cut a piece of white scotch brite pad, wrap it around - for a .50 use a .45 bore brush then I use JB bore compound, but other stuff works too.

some guys are making out like they are working on an artery. the barrel is steel and smoothbore. wrap steel wool around a brush chuck the rod in a drill and on medium speed clean it up

I've wrapped steel wool around a bore brush for a tight fit then applied whatever compound I was using to it. That is cheap, easy & works fine.
