If it's a matter of poking holes in paper, a good single shot pistol will do it at quite a distance. Mykeal indicates 6 inches at 50 yards and several of my pistols will do that too. As with most ML guns accuracy is not the issue, the energy falls off.
I can get 2" groups out of my Tradition muzzle loading 45 cal pistol at 25 yards. This is with the 240 Gr tc maxiball. Power charges from 20 g to 35 grains. Not sure what the velocity is, but this should punch right through a deer. Groups at 50 yards should be 4", I would probably limit my shots to 50 yards now. If I practice and could keep the groups tight maybe 75 yards.
