Federal .223 Rem 5.56 NATO Full Metal Jacket Boat Tail Rifle Ammunition
Federal .223 Rem 5.56 NATO Full Metal Jacket Boat Tail Rifle Ammunition is a SS109 Steel Core Penetrator bullet with 62 Grain bullet weight and 420 rounds.
The two most common 5.56 rounds are the 55gr M193 and the 62gr green tip M855, both of which are used by the US military. Both are FMJBT - Full Metal Jacket Boat-Tail - designs with a cannelure that are capable of reliable, severe fragmentation when they are moving at speeds over 2700fps and fragments to a lesser degree all the way down to 2500fps. This occurs as the projectile hits soft tissue and the bullet begins to yaw. As this happens, the bullet will often break apart at the cannelure due to the stress and separate creating a devastating wound channel.
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 turn every 12 inch twist barreled M16's that would fail to properly stabilize the heavier and much longer bullet - length being a primary factor in bullet stabilization. The NATO SS109 62gr steel core penetrator bullet is used in the M855 round. The steel penetrator makes it more effective at penetrating hard targets and such. Because of the steel core (steel is lighter than lead), the SS109 bullet is actually longer than a completely lead core 62gr bullet would be.
The Federal .223 Rem 5.56 NATO Full Metal Jacket Boat Tail Rifle Ammunition are production overruns or in some cases seconds, which may have been declared as such due to a small sampling not passing military specifications in one way or another.

Each round is brass-cased, boxer-primed, non-corrosive, and reloadable. It is both economical and precision manufactured in the United States. Shipped in a 30 caliber military ammo can.
