Frontier Cartridge Military Grade 300 AAC Blackout 125 Grain FMJ ammunition delivers reliable, American-made performance for shooters running suppressed or unsuppressed setups. Built on Hornady's proven manufacturing standards, this 300 Blackout round pairs a 125-grain full metal jacket bullet with military-grade components—brass cases, boxer primers, and consistent propellant loads—so you get the same velocities and accuracy shot after shot, whether you're training, testing a new rifle, or running drills.
The 125-grain FMJ bullet weight sits in the mid-range for the caliber, balancing velocity and terminal performance. Full metal jacket construction means a harder-hitting, deeper-penetrating round that works across a range of applications: target shooting, training scenarios, and medium-game hunting on lighter-bodied varmints. If you're building or running a 300 Blackout platform—especially one optimized for subsonic work—this is ammunition engineered to perform with the precision you'd expect from a major ammo manufacturer.
Frontier's state-of-the-art loading processes and quality control mean no surprises: each cartridge comes off the line with the same attention to detail. Brass cases are reloadable if you're a handloader, and the non-steel-core bullet composition keeps you legal at most ranges and hunting areas. This is the kind of ammo you load into your magazine without hesitation, whether you're running it through an AR-15 platform, a bolt gun, or a pistol chambered in 300 Blackout.
