The Hornady Frontier 7.62x51mm 150gr FMJ Ammunition Box of 20 Rounds is a high-grade, military-style range cartridge engineered to supply consistent cycling and dependable tracking across battle rifles, precision platforms, and modern sporting rifles. This specialized training load features a non-expanding Full Metal Jacket (FMJ) projectile crafted using Hornady’s elite component profiles to deliver smooth feeding and completely predictable recoil dynamics. Formulated with temperature-stable propellants and premium military-grade boxer primers, it is built directly on the same automated production lines utilized for official US Military contract ammunition. Utilizing premium, factory-new reloadable brass casings, the cartridge generates uniform internal pressures while maintaining 100% compliance at public or indoor ranges that strictly prohibit bi-metal steel-core options. Carefully packaged in a compact 20-round retail box, this supersonic training load serves as a cost-efficient, high-volume choice for M1A, FAL, SCAR 17, and AR-10 marksmen practicing tactical field drills.
