McMillan used to build Sharps clones. I bought this barrel from them in the late 90's. I turned the thread, tapped the action and voila, it fit nicely.
It's 416 SS, 32", 18.25" twist, 45 cal.
At this point, no chambering. Will not be used in BPCR competition.
I could stay with 45-70 government. But I could chamber in something else. Will have to do a lot of research and look for brass availability. Probably 5 candidates to work with. Not sure which way to turn, but I have 500 qty of 45-70 brass. Might be best just to stay here.
