For fully rifled barrels, add the accuracy and impact of Hornady’s SST bullet to a traditional lead-core slug, and you’ve got a shotgun that can outperform some centerfire rifles. Thanks to Flex Tip technology, SST Shotgun Slugs expand quickly and reliably. The reigning champ in slug states, SST slugs deliver sub-3″ groups at 100 yards and pack a target dropping punch up to 1,793 foot pounds of energy in 12 gauge.
