Even bubba's pissin hot 3.5 magnum bird shot is probably not getting above 300 or 400 feet vertical for starters, and then you've either got to deal with hitting it dead on with a tight pattern wad or accepting that the shot is going spread enough to make it unlikely to hit it. So far as I have ever seen the energy in a shot shell wad dissipates much faster than a regular bullet, and I think you're better off trying to hit it with a regular old 556.
