Hornady SST Sabot Slug 12 Gauge, it delivers true 200 yard accuracy and you'll achieve sub-2" groups at 100 yards. The 300 grain FTX projectile lead and fires it at a blistering 2000 fps. The sharp point increases the ballistic coefficient of the FTX, allowing it to fly faster, farther and on a flatter trajectory. On impact, the Flex Tip initiates expansion at all velocities.
Not considered to be very effective against Zombies. Because for at least a little while (maybe too long), you have flaming walking dead still coming toward you. Of which could ignite other things thus limiting escape.
