Description
Frontier Cartridge is Hornady’s answer to the demand for honest, workaday rifle ammunition built to military production standards without the premium price of a match line. It suits shooters who cycle a high round count through AR-platform rifles — whether for target practice, training drills, or varmint work — and need ammunition that feeds and fires consistently without fuss.
Each round is loaded with a full metal jacket bullet, which keeps barrel fouling manageable over long sessions and ensures smooth feeding through both semi-automatic and bolt-action platforms. The brass cartridge cases are boxer-primed, meaning spent brass is fully reloadable for those who want to recover it. Propellants and primers meet military-grade specifications, and the loading process runs under the same quality controls Hornady applies across its production lines. That consistency matters more than headline velocity figures when you are running drills or keeping a rifle zeroed across a training season.
The Lake City designation reflects that this ammunition is produced at the Lake City Army Ammunition Plant, a government-owned facility with a long production history supplying U.S. military small-arms ammunition. Rounds manufactured there are held to exacting dimensional and pressure standards, which translates directly to reliable function in tightly spec’d chambers. With a muzzle velocity of 3,240 fps and muzzle energy of 1,282 ft-lbs, the 55-grain load sits squarely in the performance range expected for this bullet weight in .223 Remington, making it a straightforward choice for maintaining zero and replicating real-world round performance during practice.
