below can be seen 44 Mag and 45-70 cartridges .... the 45-70 is considerably longer and a tiny bit wider .... with a 300 grain bullet the max recommended load for :

a 44 Mag is 15.0 grains of AA#7 which generates 1387 fps

a 45-70 is 58.0 grains of AA2015 which generates 2128 fps

no common powders are shown for these calibers so for this illustration I picked 2 powders made by the same company .... as can be seen, the difference is considerable

What about that old standby for the .44 mag 2400?

Nosler does recommend 2400 for 44 Mag but not for 45-70

over the years we've found W296 to work well for our hunting loads

Couple more comparo shots for your thread.


45/70 405 gr bullets on left, 44 mag cartridge, 45 ACP cartridge, 45/70 300 gr bullets


The 405 gr 45/70 bullet is about the same size as a 45 acp round.

I've used 26 grs. of 2400 in 45/70 with cast bullets ranging from 330 to 550 grs.
