jOe, I have some shotguns that have been honed to a minimum barrell thickness of less than 20 thousanths. They heve pretty bores and I paid more for them than I should have because of that. I don't think that whoever honed'em out did me any favors. I could probably have the backboring done a thou or so at at time down to an acceptable minimum thickness, but it would just be a bet that the pits would go away that way, and I'd still have the resulting choke change to contend with.

The way I puzzle it out, if minimal backboring would get rid of the pits I don't have a problem (other than cosmetic) anyhow, and if it didn't, I'd have wasted my money...Geo
