For deer hunting, 50 grains of powder and a ball will do the job if you stay close. Also be ready to track. I have a friend that hunts deer with that load. Another one uses 70 grains and a maxiball. The point is, no matter how powerful a load is, it does not good if you do not hit what you aim at. With 50 grains you might not get a pass through. You will get an entry and if you can put that into the vital organs, the deer might run off but it will die. So be ready to track, and maybe without a blood trail.

For moose I have no idea what kind of load would work best.
