5.56x45mm – 62 gr TMJ – Federal (XF556T62SS) – 500 Rounds

Federal 5.56 NATO is a staple for AR-15 owners who want reliable, affordable training ammunition from a major American maker. This listing is Federal 5.56x45mm 62 grain Total Metal Jacket (TMJ) training ammo, MPN XF556T62SS, sold as a 500 round case for range practice, carbine courses, and stocking up.

This load is a Federal contract overrun, packaged in plain 100 round boxes, and the cases carry FC 24 headstamps. A Total Metal Jacket bullet is fully enclosed in copper, including the base, so no lead is exposed at the back of the bullet. That reduces airborne lead at the firing line and is why many ranges that restrict exposed lead allow TMJ. The 62 grain weight is the same class as standard M855 style 5.56 loads, so it shoots close to the point of impact of the 62 grain ammo many shooters already zero with. It is a non-expanding training round intended for paper, steel, and drills, not for hunting.

This ammunition is for rifles chambered in 5.56x45mm NATO, including AR-15 rifles and carbines, the Ruger Mini-14, the Springfield Saint, and other 5.56 platforms. A common question is whether 5.56 can be fired in a rifle marked 223 Remington. 5.56 NATO is loaded to higher pressure than 223 and uses a different chamber throat, so fire it only in rifles marked 5.56 NATO or 223 Wylde, which also safely fire 223. Buying a 500 round case gives you enough for a full carbine class or several months of regular practice, and steel target shooters should check whether their range allows copper jacketed rifle rounds on steel at close distance.

Federal XF556T62SS is new production ammunition, not reloads, made in the USA. Each cartridge uses a brass case with a boxer primer and is non-corrosive, and the boxer primed brass is reloadable for handloaders who save their range brass. Buying by the case also keeps you on one production lot, so point of impact and velocity stay consistent from box to box. This case comes in factory packaging as 5 boxes of 100 rounds for a total of 500 rounds of 5.56x45mm 62 grain TMJ.
