Hornady

Hornady Superformance ammunition transcends convention and achieves the highest performance of any ammunitinon on the market today with cutting edge technological advancement in ammunition design. By using ultra progressive propellants, your favorite SST or GMX bullets achieve levels of performance that are simply unattainable with conventional propellants. In the past, shooters have used a brute force approach of using large charge weights of a slow burning powder in a larger cartridge case which ultimately this leads to more recoil and muzzle blast. The Superformance solution is an elegant approach that utilizes specialized powders at NORMAL charge weights. This in turn imparts ALL useable energy to the bullet reducing the rocket nozzle effect at the muzzle while still increasing velocity! 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 safe to use in ALL firearms, including semi-autos, lever gun and pump actions. Hornady Superformance increases rifle performance with no increases in barrel wear and felt recoil along with superior temperature stability. 20 Round Box Features and Specifications: Manufacturer Number: 82223 Caliber: .338 Winchester Magnum Bullet Type: SST Polymer Tip Bullet Weight: 200 Grains Rounds: 20 Rounds per Box Muzzle velocity: 3030 fps Bullet Diameter: .338 Muzzle energy: 4076 ft/lbs Jacket Material: Copper Core Material: Lead Tip Material: Polymer Sectional Density: .250 Ballistic Coefficient: .455 Casing: B rass Uses: Medium to Large Game
