Frontier Cartridge
Hornady Frontier Rifle Ammunition in 5.56mm NATO is a practical, domestically produced option for shooters who need reliable rounds for training, target practice, or field use. Built on time-tested manufacturing principles, this XM193 loading delivers a 55-grain full metal jacket bullet at 3240 fps, the performance envelope that has defined this cartridge since its inception. Whether you're working up marksmanship at the range, running a rifle class, or putting rounds downrange for personal defense preparation, Frontier ammunition combines consistency with straightforward, honest design—no frills, solid execution.
The foundation of Frontier's reputation rests on process: state-of-the-industry loading techniques and quality control ensure that each round performs as specified. You get brass cases paired with military-grade boxer primers, the kind of components that handle repeated reloading and survive harsh field conditions. The full metal jacket lead-core bullet design cycles reliably through modern direct-impingement and piston-driven platforms, making this load a dependable choice for both semiautomatic and bolt-action rifles chambered in 5.56 NATO.
The 50-round packaging is sized for the shooter who stocks ammunition in working quantities—enough to sustain a serious practice session or training day without excess bulk. At this performance level and construction standard, Frontier fills the role of honest-value ammunition: no premium pricing, no exotic coatings, just American-made rounds that do what they're supposed to do, round after round.
