Hornady Rifle Ammunition Features The Hornady Frontier line pairs trusted Hornady bullets with state-of-the-industry loading techniques to ensure every round performs the same as the last. This 5.56 load drives a 55 grain open tip match bullet at 3240 fps generating 1282 ft-lbs of energy at the muzzle for consistent repeatable performance on the range. A ballistic coefficient of .254 keeps the bullet stable through its flight path which matters when precision and consistency from shot to shot are the goal. Quality control procedures applied across every cartridge mean shooters can expect the same reliable function whether loading one round or running through hundreds. Each cartridge is built on a reloadable brass case paired with military-grade boxer primers giving handloaders the option to recover and reload their spent brass after the range session. The open tip match bullet design is well suited to precision practice and training offering more consistent accuracy than a standard FMJ load. Frontier Cartridge covers everything from plinking and target shooting to law enforcement training and self-defense so this load is equally at home on a weekend range trip or a structured training day. Hornady Frontier Rifle Ammunition in 5.56 gives shooters the dependable military-grade consistency they need for serious practice.
