greetings all, sorry for the delay, my father passed right before christmas and things slowed down here. I have fitted the forearm lug and believe I have some proof loads built that will tell me what I need to know. I am aware that a book on building side by side rifles has been authored and its a good writing however I feel that there could be more. I don't intend to re-write whats in print but add to. It may be in multiple volumes. With so many questions surrounding this subject and so many DG fans out there it seems a shame not to provide the good and bad of building a double rifle. Anyway if no one else is interested my son will one day have volumes to read. I have countless notebook binders full of side by side shotgun slug gun building stories and theories and quite a few pictures. Thanks for the interest.
