The Hornady Superformance 12 Gauge 2.75-inch 300-grain MonoFlex Sabot Slug 5-round box is a specialized high-velocity shotshell engineered specifically for extended-range big game hunting, trophy whitetail management, and black bear pursuit in shotgun-restricted zones. Conventional Foster-style lead slugs or low-velocity sabots frequently suffer from severe trajectory drop, rapid energy loss, and high wind drift beyond 100 yards, severely restricting effective field range. Hornady overcomes these ballistics constraints by pairing an aerodynamic 300-grain solid copper-alloy MonoFlex projectile with its specialized Superformance propellant blend, delivering laser-flat flight paths, massive downrange energy transfer, and extreme terminal penetration through fully rifled shotgun barrels.
The primary technical advantage centers on Hornady's 300-grain MonoFlex projectile architecture. Constructed from a solid, non-lead copper alloy, the bullet maintains nearly 100% weight retention upon impact, resisting fragmentation even when contacting heavy shoulder bone or dense tissue. The patented red Flex Tip polymer insert preserves meplat aerodynamics in flight while acting as an internal wedge upon impact, forcing open the deep hollow cavity to drive dramatic, reliable expansion across a broad velocity spectrum. Enclosed within a high-speed sabot sleeve, the assembly engages barrel rifling to impart precise spin stabilization before separating cleanly at the muzzle to release the projectile.
Launching its 300-grain monolithic sabot slug at a blistering 1,950 FPS muzzle velocity (generating over 2,500 ft-lbs of muzzle energy), this Superformance loading increases slug velocity by up to 200 FPS over conventional offerings without exceeding SAAMI chamber pressure limits. Assembled using high-strength 2.75-inch hulls, clean-burning progressive propellants, and non-corrosive shot shell primers, the cartridge guarantees smooth feeding, tight pressure integration, and reliable extraction in modern rifled slug guns. It stands as an elite, non-lead choice for hunters requiring rifle-like accuracy and flat trajectories out to 200 yards.
Key Benefits
- Blistering 1,950 FPS Velocity: Superformance propellants maximize velocity output without increasing chamber pressure, flattening trajectory drop.
- 100% Weight Retention Monolithic Bullet: Solid copper-alloy construction eliminates lead core separation and drives deep through heavy hide and bone.
- Flex Tip Polymer Technology: Preserves aerodynamic profile in flight and initiates rapid, reliable mushrooming upon terminal impact.
- Non-Toxic Copper Alloy Construction: Meets non-lead hunting mandates while delivering devastating hydraulic shock on big game.
