Researching on line, I read some Ken Waters load info from years back. He liked 55 gr. H-4831 with 400 gr. bullets at around 1,400 fps. For sure you'd have a case full of powder with that one.

Ive used 55 grains of H4831, Fed 215 primer, Remington cases, with a Remington 405 gr soft point. Out of my Marlin 95 with a 22 inch barrel, it gave me 1286 fps, with the 405 Remington factory load going 1224 fps. The load is very accurate with mild recoil (for a 45-70.) At this speed, the bullet does not expand much, it simply disrupts the nose a little flatter. Lots of penetration, the only one Ive recovered was under the off side hide of a buffalo bull. Deer and pigs it sails through.
It is a case full of powder with that bullet which has the side benefit of preventing the bullet from seating deeper in the case in the magazine from recoil.
