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. It really is Rocket Science.

The ammo came promptly and in good condition. Cant wait to try it out. I was buying the 5
56 NATO rounds and the online store said 5.56 and .223. The box of ammo states 5.56 NATO ONLY. Not 223. Doesn't matter for me, but someone buying for a .223 would be disappointed and have to return it. I recommend updating the product description. Again, great service

Very consistent and accurate ammunition. Recommended for battle carry. I use it in an AR15 pistol with a 10.5 inch bbl. The velocities exceed my calculations based on the shorter bbl. The chronograph readings for every shot were over 2770 fps. Note that Hornady publishes the muzzle velocity from a 20 inch test bbl.
