Wonderful story, more like a little saga,about your aquisition,...........Lots of these very good originals were mutilated , here, with .50-70 Govt. "rechambering"........"to have easier access to brass". This was a real shame,as it introduces some weird neck geometry problems into the equation.
Fact is , last I checked, Buffalo Arms had the correct brass in stock, and it was signifigantly more afordable( won't say Cheap, it just don't work that way). Some of my compadres that run the original chambering rave about it's performance.
Yer a lucky man, Roll on!
