I would delete the post above if I could.

.45-70, .405 Grenadier, and the 300gr bullets they each shoot.

.458 Sierra
Dia = .458"
Wt. = 300gr
BC = .145
SD = .204

.405 Hornady
Dia = .411
Wt. = 300gr
BC = .215
SD = .251

Left to right - .45-70 case, 7.62x54R cartridge, .405 Grenadier cartridge, .405 Grenadier case:

Published factory muzzle velocities for .444 and .45-70 are based on velocities from 24" or 26" "test" barrels.
Therefore, all muzzle velocities used for the below cartridges have been "normalized" for a 22" barrel.
