Howdy
Long time no see. Sorry to come back with a question about a shotgun that is specifically not a SXS, but I thought there was probably a pretty good knowledge base over here.
I am looking for information about how Winchester proofed the original 1887 lever action shotguns. Please correct me if I'm wrong, but I believe these were designed for Black Powder, not Nitro powder.
I am looking for any specific information anybody can provide regarding how these shotguns were proofed. Proof loads, pressure levels, etc. The only information I can find on the Web regarding proofing is mostly about English and European standards. I cannot find any information about what kinds of standards American manufacturers used.
Any information is appreciated, including pointers to other information sources.
Thanks
