I have been thinking about the 16 1/4" marlin 45-70. Just not sure if the barrel length is to short and losing to much velocity. The 454 casull with a similar barrel also has my attention. If I get another revolver it might be a 454casull.
Will the .454 casull measure up to the 45-70 both shooting 400gr hardcast factory loads in the short barrels? Are handgun powders burning that much faster compared to a rifle cartridge?
