There is a long standing tradition in the South of driving deer with hounds and using shotguns loaded with large buckshot, 0 and 00 sizes being the most popular, with 00 probably carrying the polls. It is effective, when used in tightly choked guns, out to about the range that slugs can be counted on to hit a deer's vitals out of a smoothbore shotgun with a bead for a sight.
Some of us call the big buckshot pellets "blue whistlers". A broadside shot is very effective. A frontal shot in the chest, not always so much, IMO.
