Hornady 450 Bushmaster Super Shock Tip Superformance 250gr. - 20 Rounds

Superformance ammunition is 100 to 200 fps faster than any conventional
ammunition on the market today, and achieves this performance in every gun,
without increases in felt recoil, muzzle blast, temperature sensitivity,
fouling or loss of accuracy. Superformance is a cutting edge technological
advancement in ammunition design that transcends convention and achieves
the highest performance of any ammunition on the market today.
Superformance uses ultra progressive propellants that take your favorite
SST or GMX bullets to levels of performance that are 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. Ultimately this leads to
more recoil and muzzle blast. The Superformance solution is an elegant
approach that 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 provides
increased performance, and 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.
