Frontier 556 NATO 62gr FMJ 150 Rd Overview
This is the bulk-packed version of Frontier’s 62 grain 5.56 NATO load, which is also sold in 20 round boxes as item FR260. The heavier 62 grain bullet suits the faster rifling twists found in most modern AR-15 barrels and carries a little better in the wind than 55 grain ball. Loaded to 5.56 NATO pressure in new, reloadable brass, it is aimed at shooters who train often and want consistent, American-made ammunition without constantly reordering small boxes.
Intended Use
This is training and range ammunition. Full metal jacket bullets do not expand and are not designed for hunting or defense. Use it for drills, carbine courses, zeroing and general practice, and carry a dedicated defensive load when it matters.

Bullet and Ballistics
Hornady rates this 62 grain load at 3,060 fps. The heavier bullet offers a slightly better ballistic coefficient than 55 grain FMJ, so it resists wind drift a bit better at longer ranges. It stabilizes best in 1:7 to 1:9 twist barrels; very slow 1:12 barrels may not group it well, so check on paper.
Firearm Compatibility
Fire this ammunition in firearms chambered for 5.56 NATO or 223 Wylde. Rifles marked only 223 Remington may not be rated for 5.56 NATO pressure, so check your barrel and maker’s guidance. Never use it in a 300 Blackout firearm.

Reliability and Testing
Factory ammunition from an established maker is held to consistent standards, but every firearm is a little different. Shoot at least a box through your gun before you rely on any load, and watch for clean primer strikes, smooth feeding and positive extraction. If you shoot more than one load, note where each one prints at your usual distance so you can adjust sights or holds.
Recoil and Shootability
Recoil is light in an AR-15, and the bulk pack makes it easy to run long strings of drills. Hearing and eye protection are essential.
About Frontier Cartridge
Frontier Cartridge is manufactured by Hornady in Grand Island, Nebraska. The brand focuses on dependable, American-made ammunition for practice, training and general shooting, using new brass cases and quality bullets rather than remanufactured components.
Why Buy in Bulk
A 150 round pack covers a typical carbine class or several range trips without opening multiple small boxes, and it keeps you on a single production lot. That consistency means your zero, point of impact and feel stay the same from session to session, which is exactly what you want when building skills.
Storage and Care
Store ammunition in a cool, dry place in its original box, away from solvents and lubricants that can contaminate primers. Inspect rounds for dents, loose bullets or corrosion before loading, and set aside anything that looks damaged.
