i shoot 27grs imr 4198 with a 300gr cast bullet(no filler) for 1200-1300fps in a 1876 made in 1883. its four inches high at 50yds and right on at a 100yds. with your rifle made with modern steel you could go a little higher and also use jacketed bullets. cases are easy to make,shorten 45-70 cases and you may have to thin the rim a little. i took a 45-70 seat-crimp die and had it shortened 3/8 inch(it still can be used on regular 45-70,s) to seat and crimp the 45-60,s. eastbank.

AA5744 Load

4198 Load

I used almost nothing other than 4198 for my 45-70 ammo until I gave AA5744 a try. I usually stick with time tested powders that are associated closely with a particular caliber but this time I'm making an exception. AA5744 was specifically designed to better fill large Black Powder cases and IMO it works very well. I found it to be an accurate powder that's easy to use. I like it, I like it a lot! (with a 405gr LRNFP bullet)
