Reloading for 45/70 is.. used to make a box or two at a time, now it's 100. Everything from 300-340gr cast at subsonic over unique or trail boss to 480-500gr at shoulder breaking ~1500-1600 ish.. I'd hunt polar bears with one of Ben's 480gr hard cast over 33-36gr of IMR 4198.. That's my load in my rifle, don't start there.
Another .45-70 fan here.
It's a great cartridge to reload with minimal effort.
My current favourite powder is Trail Boss, topped off with some dacron as filler.
If you are working up a load, with a minimum amount of brass, you can do it at the range with a Lee Hand Tool, dies, case lube, scale (most important IMHO) hand primer, primers, powder(s) and bullets.
If you're using new brass, remember to trim and de-burr it.
I agree whole heartedly about Ben's 480 WFN, although I'm partial to 3031.
