Description
The Hornady SST slug is built for deer hunters running fully rifled barrel shotguns who want genuine extended-range performance from a 12-gauge platform. It is not a general-purpose shell — it is purpose-designed to take full advantage of the spin imparted by a rifled bore, which stabilizes the projectile in a way that smoothbore barrels cannot replicate, allowing consistent accuracy out to ranges where traditional Foster-style slugs have already lost their usefulness.
The bullet itself uses Hornady’s Flex Tip design, the same concept applied across their centerfire SST line. On impact, the polymer tip initiates expansion reliably even at the lower velocities that occur at distance, helping the projectile open consistently rather than relying solely on hydraulic pressure. The 300-grain slug leaves the muzzle at 2,000 feet per second, generating significant downrange energy in a package that still fits a 2-3/4-inch chamber. That combination of weight and velocity produces a relatively flat trajectory for a shotgun slug, which is what makes true 200-yard shooting practical rather than theoretical.
Because this load is optimized for rifled barrels, it should not be fired through a fixed choke or a smoothbore barrel — the rifling on the slug shank is designed to engage the bore, and running it through the wrong platform will both degrade accuracy and risk damaging a tightly constricted choke. Hunters who already have a dedicated slug gun with a rifled barrel will find this a well-matched load for whitetail and similarly sized game at distances that exceed what most slug ammunition is designed to handle.
