Recently, I had discussion with a friends, and everybody had his own idea about cal. 45 boolit for various cartridges. After some head scratching, I came up with this design that incorporates all features required for BP revolvers, as well as center-fire cartridges, like 45 Colt, 45 Schofield and 455 Webley/Eley.
So, here we have .457" dia, 255 grain, FP and HB:
Since the mold will be Cramer style, bottom pins for hollow base could be flipped, or separate pins for solid base used, solid base boolit will have 290 grain.
If there is interest, I will contact Miha at MP-Molds.
