223 Rem – 55 Gr FMJ-BT – Hornady (80275) – 500 Rounds

Shooters who want practice ammo built with the same care as a premium load often reach for Hornady. This listing is Hornady Custom 223 Remington 55 grain full metal jacket boat tail ammo, MPN 80275, sold as 500 rounds in 50 round boxes for AR-15 training, varmint rifle practice, and steel target shooting.

Hornady rates this load at 3,240 fps with 1,282 ft-lbs of muzzle energy. The 55 grain boat tail bullet offers a slightly better ballistic coefficient than flat base ball ammo, shooting flat and holding velocity well across common carbine distances. Light recoil makes it easy to spot hits and run fast drills. Because it is a full metal jacket bullet, it does not expand, so it is for target practice and training rather than hunting, where an expanding bullet is required.

This ammunition fits rifles chambered in 223 Remington and 5.56x45mm NATO, including AR-15 rifles from Ruger, Smith and Wesson, Colt, and Daniel Defense, plus the Ruger Mini-14, Savage Axis and 110, Tikka T3x, Howa 1500, CZ 600, and Mossberg MVP. A common question is whether 55 grain bullets stabilize in a fast 1:7 barrel. Yes. Faster twist barrels stabilize light bullets well, and 55 grain loads also work in slower 1:9 and 1:12 barrels. Another common question is whether 223 ammo is safe in a 5.56 chamber. Yes. 223 Remington is safe in 5.56 and 223 Wylde chambers.

Hornady 80275 is new production ammunition, not reloads, made in the USA in Grand Island, Nebraska. It uses reloadable boxer-primed brass cases and non-corrosive primers. This listing ships as 10 boxes of 50 rounds for 500 total from one lot, which keeps your zero and function consistent from the first magazine to the last. The 50 round boxes are also convenient for loading a full set of 30 round magazines at the range.
