Federal XM855 is the commercial version of the US military M855 green tip round, the 62 grain standard for 5.56 NATO. This listing is Federal American Eagle XM855 5.56x45mm NATO 62 grain green tip ammo, MPN XM855FL, sold as a 500 round case.
The M855 bullet has a lead core with a small steel penetrator in the nose, identified by its green tip. It is loaded to 5.56 NATO pressure. The heavier 62 grain bullet holds velocity and resists wind better than 55 grain M193, and it stabilizes best in 1:7, 1:8, and 1:9 twist barrels, which covers most modern AR-15 rifles. Shooters choose XM855 to match military ballistics, to zero rifles that will run it, and for training at longer distances. A full metal jacket bullet is not designed to expand, so this is training ammunition rather than a hunting load.
This ammunition fits rifles chambered in 5.56x45mm NATO or 223 Wylde, including AR-15 rifles and carbines, the FN SCAR 16, Sig MCX and M400, IWI Tavor, HK416 and MR556, and Springfield Saint. A common question is whether green tip ammo is allowed at my range. Many indoor ranges and some outdoor ranges ban steel penetrator ammunition because it can damage steel targets and backstops, so check your range rules first, and keep a safe distance from steel targets. Another common question is whether XM855 shoots well in a 1:12 twist barrel. Many 1:12 barrels struggle with 62 grain bullets, so 55 grain ammunition is a better choice there. Do not fire 5.56 NATO in a rifle marked only 223 Remington.
Federal XM855FL is new production ammunition, not reloads, made in the USA. Each round uses a reloadable brass case with a boxer primer and is non-corrosive. This case comes in factory packaging as 25 boxes of 20 rounds for a total of 500 rounds of 5.56 NATO 62 grain XM855. Buying by the case keeps you on one lot so your zero holds.

Ordering through Bulkmunitions was easy and efficient! Now if only they sold 30-06. I plan on purchasing ammo from them the rest of my life especially since they donate back to Christian organizations.
