I've pretty much decided to use it and not hone nor polish the bore. It's really not all that bad and doesn't seem to affect the patterning. It's not my main gun by a long shot, just a kind of trifle.

So long as I don't look down the bore too often, I should be OK. I don't think polishing the bore is nearly as questionable as lengthing the chamber, which I am not going to do either.
