The Sierra Tipped MatchKing (TMK) 77 grain is a precision-focused .22 caliber (.224) projectile engineered for consistent long-range performance. An acetal resin tip reduces drag to improve the ballistic coefficient and supports reliable feeding in magazine-fed platforms. The boat-tail profile and jacketed construction help maintain stability and predictable flight characteristics.
