Product Summary

Hornady Superformance Ammo is 100 to 200 fps faster than most conventional ammunition on the market today! Designed with cutting-edge technological advancement in ammunition that transcends convention. Superformance uses ultra-progressive propellants at normal charge weights that impart all useable energy to the bullet, reducing the rocket nozzle effect at the muzzle while still increasing velocity. Safe to use in all firearms, including semi-autos, lever gun, and pump actions, without increases in felt recoil, muzzle blast, temperature sensitivity, fouling, or loss of accuracy.

Monolithic, copper alloy GMX bullets deliver controlled expansion and 95+% weight retention. Crimping cannelured and pressure-relieving grooves reduce both bearing surface and fouling, and aid in consistent reloads. High weight-retention is a significant benefit to the GMX and monolithic family of bullets. Box of 20 rounds. Shipped ground only.
