Thanks Brian - good point. I did consider that and you are clearly right. In my case it wouldn't shift enough to be problematic but that would have to be considered on a case x case basis. I wouldn't want to go more than about .02 off center, personally. The area I would want to study closely and understand clearly before adjusting flats would be the fore iron.
I have to say, I'm really glad that Tom asked his question because I got the chance to learn that I don't know what it is I think I know about double gun design. I've got some studying to do before so much as putting a file to any working surface. The barrel face is nested in the breech face - that sends forces somewhere, and it's not how I visualized it, at all. Heck, I'm feeling uneasy about a simple shim at this point. I can gather and cipher some numbers and all but, can anyone point me to some legitimate working / manufacturing drawings of a box-lock action? Reference materials that will short-circuit the learning curve?
