The most useful information I can add is to be wary of using HP's from a rifle at close range. I've seen poor penetration with 240 grain HP's at close range with rifle velocities, (1,750-1,800 fps).
This. I've killed a pile of deer with 44 revolvers and one with a 20" lever gun. Revolver loads pick up about 300 fps in a 20" barrel. A lead SWC or LFN will usually hold together better than the kind of JHP you find in most factory revolver loads.
To answer the original question, a 44 rifle is a good choice for deer out to 100 yards or a bit more.
