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 which 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 provides increased performance, and is safe to use in all firearms, including semi-autos, lever gun and pump actions.

I used this ammunition during a recent guided hunt in Australia. We were in New South Wales, and were doing a long range hunt for Koala Bears. I was regularly smacking these furry darlings at ranges up to 600 yards, as measured by my Burris Eliminator III laser-rangefinding scope. The terminal effects were devastating. It was particularly remarkable because Koalas are generally taken by head shots, so not as to damage too much meat. Their pelts, once thoroughly tanned, also make excellent parchment or lamp shades. I bagged my limit (28) in just 3 days, then got to lie on their lovely beaches for the next 4 days. A truly remarkable hunt, made possible by Hornady's excellent ammunition.
