Now that's an interesting article. IMO, the money quote:

Ah, but the big surprise comes at 0-degrees of elevation which would be more or less a typical shot at a deer on level terrain. Here the rifle, shotgun and muzzleloader projectiles travel 1,408', 840', and 686' respectfully plus ricochet distances of 3,427', 4,365', and 3,812' respectfully. Now the total distances traveled by the projectiles are 4,835' for the rifle, 5,205' for the shotgun and 4,498' for the muzzleloader.

So assuming a solid ricochet, a ML bullet shot level could travel 4498 feet. Surprising.
