I just got an 1866 in 44-40 and am in need of a suitable mold. Use will be for plinking and maybe cowboy action shooting. Arsenal has this one http://arsenalmolds.com/bullet-molds...it=99999999999
That has my interest because of the light weight using less lead and it has a generous lube groove in case I want to shoot black powder. I've never used a boolit with such short driving band. Do you think it will cause problems with cowboy level loads? Arsenal also has another boolit at 210 grains that looks like a good design but I'd rather go with the lighter one if I can get away with it.
