Hornady Frontier 223 Rem 55gr FMJ 20rd Box

Frontier Cartridge puts Hornady bullets on top of military grade primers and propellant. This is the everyday 223 Rem load: a 55gr full metal jacket at a listed 3,240 fps and 1,282 ft-lbs.

It is the round for zeroing, drills and high volume practice from an AR-15 or a bolt action 223. The 55gr FMJ matches the weight most shooters already zero with, so it is easy to swap in for training. It is loaded as 223 Rem, not 5.56 NATO. 20rd box.
