OK, after further review, I've checked the barrel end and the end has been reamed over size. So that there's no chance of bullet bounce.
As far as the polishing process goes, I don't know as I hired a local gunsmith to do it for me. I've recently seen some of his work and was all googly eyed.
I asked him if he could do some stuff for me and I'm very happy with the end result.
At a very reasonable price I might add.
I've already had a couple requests to have one done.
He has an FFL, so shipping directly to him is not a problem.
He also does many many other custom things. Not just wheelguns either.
Jewling, trigger jobs, Action jobs, Competition stuff.

More stuff to follow, I'm sure of that.
