Hornady Frontier 7.62x51mm NATO 150 Grain Full Metal Jacket Brass Cased Rifle Ammo, 20 Rounds, FR390
Hornady Frontier FR390 is a 7.62x51 NATO-style FMJ training load for shooters who want a current Hornady Frontier range option instead of hunting or match .308. It belongs on the shortlist for semi-auto .308 owners, especially M1A, FAL, SCAR 17, and AR-10 shooters who prefer lighter FMJ ball for high-volume range work.
Current retail evidence identifies the live Hornady Frontier 7.62x51 NATO FMJ product as FR390 with a 150gr FMJ bullet in 20-round boxes. Accuracy is not match-grade; think zero checks, positional practice, function testing, and steel at ordinary training distances rather than precision load development.
The case for Frontier over generic commercial .308 FMJ is application fit: if your rifle is set up around 7.62 NATO-style ammunition, this is the kind of load to test before spending match-ammo money on practice. Availability can move around, so treat it as a buy-when-you-find-it option and cross-shop other brass-cased 7.62 NATO FMJ loads if current Frontier inventory is thin.
