This is new head stamp military contract green tip M855 ammunition made by Winchester in their East Alton, Illinois plant for the US Military. Winchester Q3269. Federal and Winchester are the domestic suppliers of M855 for the US Military. The NATO SS109 62 grain steel core “penetrator” bullet is used in the M855 round. This ammo is more effective at penetrating hard targets. The US made M855 is painted with a green tip to distinguish it from M193, so that troops do not shoot M855 in their 1:12″ twist barreled M16’s that would fail to properly stabilize the heavier and much longer bullet (length being a primary factor in bullet stabilization).
This is new production. Grade 2 Winchester M855 had been previously been sold in the plain white box labeled M855 Penetrator.
