1000 Rounds of 62gr FMJ M855 5.56x45 Ammo by Winchester USA Bulk Pack

Is your AR-15 hungry? Then don’t just feed it – treat it to a regular smörgåsbord with this case of 1,000 5.56x45 rounds courtesy of Winchester!

This M855 round’s 62 grain bullet has a little more mass than a regular M193 round. As such it is better stabilized by a faster twist barrel (1:9 or 1:8), but in return it retains greater momentum downrange.

The bullet has a conventional gilding metal jacket – concentric enough to promote target-grade accuracy, and hard enough to feed reliably in any semi-auto. The bullet’s green painted tip shows that its core contains a steel penetrator tip. Like its name implies, a penetrator bullet more reliably pierces barriers such as sheet metal at ranges up to around 330 yards.

Winchester loads this new production ammo with reloadable brass cases and clean-sparking primers and propellant. You can see that these new cases have been annealed, thus ensuring their suppleness over the course of multiple successive handloads.
