Special Features
- Frontier Cartridge is a Hornady brand built specifically to deliver military-grade ammunition using the same loading techniques and quality control standards applied across Hornady production lines.
- The 62-grain FMJ bullet uses a boat tail profile, which stabilizes the projectile in flight and contributes to the .274 G1 ballistic coefficient for a flatter trajectory at distance.
- Brass casings are fully reloadable, giving handloaders the ability to reclaim and recondition spent brass for additional use.
- Boxer primers provide reliable ignition across a wide range of temperatures and are compatible with standard decapping and repriming tools used in common reloading setups.
- The non-corrosive formulation protects bore and chamber surfaces during extended range sessions without requiring immediate post-range cleaning to prevent damage.
- Each case packs 25 boxes for a total of 500 rounds, designed for shooters who buy in volume and want consistent lot-to-lot uniformity across a full training supply.
Practical Benefits
- The 5.56x45mm NATO chamber pressure rating makes this load compatible with AR-15 and other modern sporting rifles chambered in 5.56 NATO, delivering the full pressure cycle those platforms are designed to run.
- The 62-grain bullet weight works well for general range training, target drills, and carbine courses where consistent cycling and reliable feeding matter more than specialized terminal performance.
- The FMJ profile feeds smoothly through semi-automatic actions and helps reduce the chance of nose-diving or feed-related stoppages during rapid-fire strings.
- At 20 rounds per box and 25 boxes per case, you can stock a full 500-round training supply from a single purchase and maintain lot consistency across an entire course of fire.
- If you reload, the reloadable brass cases give your spent casings a second life and reduce your long-term cost per round.
- Whether you run carbine drills, train new shooters on an AR platform, or simply need a dependable bulk supply for the range, FR260 gives the high-volume shooter a consistent, no-compromise load to build on.
Frontier Cartridge FR260 in 5.56x45mm NATO is a proven platform for the shooter or trainer who demands military-grade consistency, reloadable brass, and reliable semi-automatic feeding in every box.
