I have never lengthen a chamber, but I've "eased" the forcing cones on a few older guns. FWIW, I don't think I'd do it again. For one thing, I don't know that I could tell the difference. It's not like these were skeet guns; shooting them ten times a day is a lot. Destroying originality is like loosing virginity ... it seems like a very good idea at the time, but there's no going back.
As I've gotten older I've decided that the world is full of shotguns. If you're not satisfied, it's easier, cheaper and less destructive to just find a different one than it is to make the one you've got into something it ain't. TT
