Atomic Ammunition 00459 Rifle Match .223 Rem 77gr Tipped MatchKing - 20 Rounds/Box, 10 Boxes/Case

The Atomic Ammunition .223 Rem 77gr Tipped MatchKing is a match-grade rifle round built for shooters who demand precision at distance. Loaded with the respected Sierra MatchKing bullet—now in tipped form for improved ballistic performance—this ammunition delivers the consistency and accuracy expected on the range and in competitive shooting. Each round is assembled to exacting standards, making it a solid choice for AR-15 builds, bolt rifles, and precision shooting applications where repeatability matters.

What sets match ammunition apart is the attention to quality control in every stage: case selection, powder charge consistency, and bullet seating. The 77-grain Tipped MatchKing bullet profile is optimized for medium to longer-range work, offering a high ballistic coefficient and reliable trajectory. Whether you're fine-tuning loads, working up load data, or simply want ammunition you can trust to shoot the same way every time, this is the stuff serious shooters reach for.

Atomic delivers this ammunition in practical packaging: 20 rounds per box, and a full case contains 10 boxes (200 rounds total). That's enough to run a proper range session or stock up for serious practice without buying in bulk sizes that don't fit your needs. If you're loading an AR-pattern rifle or a .223 bolt gun and you're tired of inconsistent commercial options, match-grade ammunition eliminates one variable from the equation.
