528 rounds of green tip ammo in .30 cal ammo can.

Key Specifications
Bullet Weight: 62-grain full metal jacket (FMJ).
Core Design: Features a steel penetrator tip placed in front of a lead core inside a copper jacket.
Caliber & Pressure: Though often casually called ".223 green tip," it is loaded to 5.56x45mm NATO pressure specs (which are higher than standard .223 Remington).
Casing: Brass-cased, Boxer-primed, and often reloadable (marked "LC" on the headstamp for Lake City Army Ammunition Plant).
 
Common Uses & Limitations
Barrier Penetration: Designed to punch through light steel, vehicle glass, and heavier clothing better than standard 55-grain .223 bullets.
Not Armor-Piercing (Legal Status): Under U.S. federal law, it is classified as a sporting/military rifle cartridge rather than handgun armor-piercing ammunition, making it legal for civilians to own (though some indoor or private ranges ban it).
Range & Defense Restrictions: Many indoor and outdoor shooting ranges prohibit green tip ammunition because the steel core causes sparks and damages steel backstops or targets. It is generally not recommended for home defense because the steel core can over-penetrate walls and pose a risk to bystanders.
