I use that bullet and am very happy with it, but as with all hollow base bullets, you don't want to overdrive it too hard (fast). A piece of the skirt can break off and lodge in the barrel.
That being said, just do what I did: Go to Hodgdon's website and look up their 45-70 loads. They list 3 levels, all guns, lever guns, and modern high strength guns.
IIRC, I mostly use IMR 4198 and SR4759.
