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 .223 Rem load drives a 55 grain FMJ bullet at 3240 fps generating 1282 ft-lbs of energy at the muzzle for flat-shooting reliable terminal performance on the range. A ballistic coefficient of .243 keeps the bullet stable through its flight path which matters when consistency from shot to shot is 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 non-lead-free FMJ bullet is well suited to high-volume practice and training holding up to repeated cycling through semi-automatic rifles without excessive fouling or feeding issues. Frontier Cartridge covers everything from plinking and target shooting to law enforcement training so this load is equally at home on a weekend range trip or a structured training day. Hornady Frontier Rifle Ammunition in .223 Rem gives shooters the dependable military-grade consistency they need for serious practice.
