Frontier® Cartridge by Hornady® 7.62x39mm Ammunition – 123 Grain Full Metal Jacket – Premium Brass Case – 20 Rounds Per Box – FR420
The Frontier® Cartridge by Hornady® 7.62x39mm M43 Ammunition (FR420) is a premium, American-made centerfire rifle round masterfully engineered to elevate the performance, cleanliness, and accuracy limits of classic intermediate platforms. While the global 7.62x39mm market is oversaturated with cheap, military-surplus imports featuring erratic steel cases, corrosive Berdan primers, and harsh bimetal-jacketed bullets that rapidly erode rifling lines, the Frontier series thoroughly breaks away from those structural liabilities. This match-grade training and defense solution (090255729528) couples standard-setting internal ballistic formulas with premium domestic components, serving as an exceptional primary feed option for AK-47 variants, SKS carbines, and modern bolt-action or AR-pattern hunting rifles.
The structural foundation of this centerfire load relies on a premium, factory-fresh solid brass cartridge case. Unlike steel-cased alternatives that lack elasticity and lead to rough extraction cycles, failure-to-feed jams, and heavy carbon blowback inside your receiver uppers, Frontier’s high-grade brass promotes perfectly smooth, reliable chamber cycling. This ammunition utilizes highly stable, military-grade **Boxer primers and specialized clean-burning propellants**, keeping your firing pins and gas networks clean while leaving the brass completely reloadable. The defining technical edge of the FR420 configuration is its integration of an authentic **Hornady® 123-grain Full Metal Jacket (FMJ) projectile**. Engineered with a lead core and a thick copper jacket, this target-friendly bullet features a non-magnetic profile that lets you train freely at indoor ranges where steel-jacketed surplus rounds are completely banned.
The operational core of this platform is anchored by state-of-the-industry loading techniques and stringent quality control protocols enforced directly by Hornady. Flying out of the muzzle at a uniform **2,340 feet per second (FPS)** with 1,495 ft-lbs of kinetic energy, it yields a highly consistent, flat trajectory loop that simplifies holdover calculations up to 200 yards. Packaged in a compact 20-round box, this non-corrosive milestone provides an excellent cross-application framework—perfectly balancing affordability and precision for high-volume range plinking, competitive 3-Gun tracking strings, tactical training, and light varmint control. This American-engineered upgrade maximizes shot-to-shot consistency for operators who refuse to cycle dirty ammunition through their firearms.
Includes: (1) Factory-Sealed Box of Frontier Cartridge 7.62x39mm 123gr FMJ Ammunition (20 Rounds Total).
*Range Compatibility Guidance: The Hornady FMJ bullets loaded inside this Frontier Cartridge line are strictly non-magnetic and contain zero steel inside the jacket or core structure. They will easily pass target magnet tests, making them completely safe and approved for indoor shooting bays or private clubs that ban foreign steel-case ammo due to fire and backstop damage risks.
