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

Customer Comments
"I unexpectedly needed to find some non toxic waterfowl loads quick, for a .410 shotgun. Mack's was the only one that had Hevi-Shot in .410 with #5 shot. The process of ordering was easy, and it was quickly shipped to my door. I couldn't be more happy with the Mack's, and it made it possible for a little boy to enjoy his first duck hunt." Oct 2015
