    Product Description


    Hornady 81583 Superformance 280 Remington 139GR SST 20 Box/10 Case

    Superformance ammunition is 100 to 200 fps faster than conventional
    ammunition, and achieves this performance in every gun, without increases
    in felt recoil, muzzle blast, temperature sensitivity, fouling, or loss of
    accuracy. Superformance uses ultra progressive propellants that take your
    favorite SST or GMX bullets to levels of performance simply unattainable
    with conventional propellants. In order to get more velocity in the past,
    shooters have used a brute force approach with large charge weights of a
    slow burning powder in a larger cartridge case which ultimately leads to
    more recoil and muzzle blast. The Superformance solution utilizes
    specialized powders at normal charge weights that impart all usable energy
    to the bullet, reducing the rocket nozzle effect at the muzzle while still
    increasing velocity. Superformance is safe to use in all firearms,
    including semi-autos, lever gun and pump actions. Increases in rifle
    performance, no increases in barrel wear and felt recoil, along with
    superior temperature stability are all realized with Superformance
