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 62 grain "green tip" M855 is used by the US military. 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).
