Hornady

Frontier® Cartridge is a division of Hornady® that uses state-of-the-industry loading techniques and quality control procedures to ensure the reliability and consistency of every round. Made in the USA with military-grade brass cartridge cases, primers and propellants.

PLEASE NOTE: While the 5.56x45mm round will fit in a .223 Remington chamber, 5.56 is a military round that is loaded to higher pressures, and is therefore not recommended for use in rifles chambered for .223.
