If it were me I'd probably run a 45-70 with a 300 around 2200.. With a decent zero it'll shoot to 200 without much trouble. If you have a reticle that you can holdover with I'd take it to 300, with dialing it being my preferred way of getting it done.
My partner has a Ruger 45-90... I think that might be pretty cool too with pointed bullets.
