I have been handgun hunting a long time. I used to load to the max with 240 / 300 grain XTP's. They killed deer. Then I started using 250 / 300 grain hard cast semi wadcutters and flat nose style bullets at about 1000 / 1100 fps, and found they were more pleasant to shoot, and killed deer about the same; usually the deer would run 20 / 50 yards and fall. An XTP hollow point loaded to max, in the chest MIGHT drop a deer a little quicker, but on angle shots, no difference, except the hard cast will penetrate deeper, and usually exit, giving a good blood trail (especially desirable on bear, as bullet holes seem to fill up with fat, limiting the blood trail). What ever load you choose, practice, practice, practice, and limit your shots to the range in which you can keep all your shots on a paper plate from a field position. By the way, the Redhawk is an excellent and strong revolver. I have yet to wear mine out, and not for lack of trying..
