Hornady SUPERFORMANCE GMX Ammunition 5.56x45mm NATO 55 Grain Gilding Metal Expanding Boat Tail Lead-Free Box of 20
You must be 21 years or older to order ammunition. Ammo must ship UPS ground. Due to Department of Transportation regulations, we cannot accept returns on ammo. Please check local laws before ordering.
Loaded with Hornady's Gilding Metal Expanding (GMX) bullet, this bullet is harder and tougher than a copper bullet and also helps to reduce fouling in the barrel. Made with the same polymer tip bullet used in Hornady's A-Max, InterBond and SST rounds. A GMX bullet expands 1-1/2 times its original size and retains 95% of its original weight. The boat tail design reduces bearing surface in order to increase accuracy and consistency. This bullet gives hunters an expanding monolithic bullet that delivers ultra-flat trajectories and devastating terminal performance. Hornady also lists these as "California Compatible".
Please Note: While the 5.56x45mm NATO will fit in a .223 Remington chamber, the 5.56 is a military round that runs at higher pressures than its .223 counterpart and is not recommended to be fired in a .223 Remington chamber.
