HORNADY MFG CO SST

Hornady 81353 Super Shock Tip 257 Roberts SST 117 GR 20 Round Box

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
ammunition.
