Hornady Superformance 7mm Rem Mag 139gr SST Ammunition

Superformance 7mm Rem Mag factory load | 139gr SST polymer-tipped bullet, BC 0.486 | 3240fps muzzle velocity, up to 200fps faster | InterLock ring for controlled expansion | For deer stalking, management and target work | Stable from sub-zero to desert heat | Box of 20 rounds, item 80593, FAC required

Hornady's Superformance load pairs the 7mm Remington Magnum with a 139-grain SST bullet and progressive propellants that lift muzzle velocity by up to 200fps over conventional factory rounds, without raising chamber pressure or felt recoil. The listed muzzle velocity is 3240fps and the SST carries a ballistic coefficient of 0.486, so trajectories stay flat and predictable across the longer ranges this calibre is built for. The polymer-tipped SST drives back into the lead core on impact for fast, controlled expansion, while the InterLock ring keeps core and jacket together for dependable weight retention and deep penetration. That makes it a sound choice for stalkers and deer managers working open hill or larger species, as well as anyone chasing consistent groups on the range. The propellant is engineered to perform reliably from arctic cold to desert heat, so point of impact holds across the seasons. Supplied in factory boxes of 20 rounds, item number 80593. A valid firearms certificate is required and proof must be provided before purchase.
