Well sort of, there are Many ways to remove metal from the bore and a Sunnen hone would be great but as you said, it is not something most gunsmiths have. There are other ways though. The lead lap has been used for this purpose as long as gunsmiths have honed bores. There is a system that Dennis Potter showed me where he had modified Sunnen parts so they can be driven by a hand drill, genius and it works. I use backbore reamers. I'm sure others have other techniques. I recently cleaned up a set for a client that were .722 and deeply pitted, they really looked bad. We ran the .730" reamer down them and adjusted the chokes afterward. Not perfect but damn close and we still had over .030" walls in the end.

I think that's my Fox pin-gun barrels Steve is referring to. Wonderful job! Steve may not think I his job was perfect, but I do. I'm opening the dove season with the gun. SKB has done some great work for me over the years. I thought it might be appropriate to just say thanks...Geo

i use the sunnen system that Dennis Potter had, works great takes out small amount's and you can get a nice finish.we saved some parker barrels that i thought couldn't be save. i did check the wall thickness quite a lot.

Don't buy them in the first place. A lot of folk don't recognize genius when they see it, or when one says something. Too bad. Best, Ted

Steve, what is the most you have had to take out to clean up a set of barrels that were deeply pitted? In this case it was .008 but have you had to go larger than that? What do use for minimum wall thickness and at what point in the bore?

I have taken out more than .008", I can not remember the exact amount, it was from a damascus barreled Bonehill. I always use a wall thickness gauge and check the barrels throughout. I like at east .025" walls. The Bonehill mentioned earlier was over .045" MWT to begin with. Lots of metal to work with and it remained plenty safe, If memory serves on that one I opened the bore up a bit over .012" so it ended up with nearly .040" walls. On most guns cleaning up .0025" on a side will do wonders.
