45-70 with many powder works. I ahve used RE-7, 4198, Benchmark, H322, 4895, Varget, 335, and 748. They all did quite well. They all need a pretty full case to really burn well and that means velocity and recoil are up.
For a moderate recoiling load I will always turn to 2400. And not just in 45-70. I am to 2400 what Ben is to plain based bullets.
