5.56x45mm – 55 gr FMJ-BT – Federal (XM193BKX) – Bulk 1000 Rounds

Loose bulk packaging removes the cost of individual cartons and lets you fill magazines straight from the box. This listing is Federal American Eagle 5.56x45mm NATO 55 grain full metal jacket boat tail XM193 ammo, MPN XM193BKX, sold as a 1,000 round bulk pack.

This loose-pack XM193 is listed at 3,240 fps with 1,282 ft-lbs of muzzle energy. XM193 is the commercial version of the military M193 ball round, loaded to 5.56 NATO pressure. The boat tail FMJ is accurate enough for zeroing and practice at typical carbine distances and stabilizes in every common AR twist. It is a training round, ideal for drills, carbine courses, and steel targets. A non-expanding bullet is not appropriate for hunting.

This ammunition is for rifles chambered in 5.56x45mm NATO or 223 Wylde, including mil-spec AR-15 rifles and carbines, the Ruger Mini-14 marked 5.56, the Springfield Saint and Saint Victor, the IWI Tavor X95, the Sig MCX, and the FN SCAR 16S. A common question is whether this ammo can be shot in a 223 Remington rifle. It is not recommended, because 5.56 NATO runs at higher pressure than a 223-only chamber is designed for. Another common question is how to store a loose bulk pack. Transfer the rounds to sealed ammo cans with desiccant to keep them dry over the long term.

Federal XM193BKX is new production ammunition, not reloads, made in the USA by Federal. It uses reloadable brass cases with non-corrosive boxer primers. This listing ships as 1,000 rounds of 5.56 NATO 55 grain FMJ-BT packed loose in one bulk box. Bulk buying from one lot lowers your cost per round and keeps the same load in every magazine for a full training season. One thousand rounds is roughly a two-day carbine course plus months of follow-up practice for a single shooter.
