Atomic .223 Rem 77gr Tipped MatchKing Ammo, 50-Round Box

Atomic .223 Remington 77-grain Tipped MatchKing ammunition (part no. 00452) pairs a heavy-for-caliber match bullet with a reliable factory load from Atomic. Sierra’s Tipped MatchKing adds a polymer tip to the legendary open-tip match bullet design, improving the ballistic coefficient for flatter flight and less wind drift at distance while keeping the accuracy pedigree that made MatchKing a favorite among precision shooters. At 77 grains, this is a heavier bullet than the typical 55- or 62-grain range ammo, giving it better long-range performance out of a fast-twist AR-15 barrel. It’s a strong choice for shooters running a precision AR build who want match-grade consistency without hand loading.
