I'm still considering building a 44-77 but am concerned about availability of brass. Anyone here shooting one? If so where did you get brass or what did you make it from. I understand that it's possible to make it from 45-90 but, the base is 0.015" small. I read that in the distant past Remington made some 44-77 with steel heads and brass bodies. The bodies of the brass portion had a solid base that a screw passed thru and fixed the tube to the base. The screw formed the primer pocket. I suppose I could do something along that line but what a lot of work just to have a classic Sharps caliber. I would much rather buy than make the brass. Suggestions? Ideas?
