IMI Razor Core 5.56 NATO 77gr Sierra Matchking HP - Box of 20

IMI Razor Core pairs the legendary 77-grain Sierra MatchKing hollow point boat-tail bullet with 5.56 NATO-spec cases, giving precision shooters a similar concept to the U.S. military's Mk 262 loading at a more accessible price point.

Features:

• 77-grain Sierra MatchKing hollow point boat-tail bullet with a cannelure for consistent seating
• Muzzle velocity around 2,740 fps and muzzle energy near 1,283 ft-lbs from a 16-inch barrel
• Annealed brass cases with neck and primer sealant for reliability in adverse conditions
• Crimped, lacquer-sealed military-style primer for dependable ignition
• Higher ballistic coefficient than standard 55- to 62-grain 5.56 loads for reduced wind drift
• Requires a 1:8 twist barrel or faster to stabilize the heavier 77-grain bullet
• Similar in concept to the U.S. military's Mk 262 loading, though a distinct product

The 77-grain Sierra MatchKing has built its reputation on winning more rifle competitions than every other manufacturer's target bullet combined and pairing it with 5.56 NATO-spec cases gives precision rifle owners a genuinely accurate loading for extended-range work without paying custom-load prices for similar performance.

IMI has manufactured combat-proven ammunition and defense systems since 1933, qualified for use by the Israel Defense Forces, the U.S. military, and NATO nations, bringing that same manufacturing pedigree to the commercial ammunition market.
