Product Description The Sierra Tipped MatchKing (TMK) 22 Caliber .224" 77 Grain bullet is an evolution of Sierra&';s legendary MatchKing line. By incorporating an acetal resin polymer tip, Sierra has further refined the aerodynamic profile of this world-renowned bullet, reducing drag and delivering an enhanced ballistic coefficient for superior long-range accuracy. The polymer tip also promotes reliable feeding in magazine-fed firearms, making the TMK equally at home on the precision target range or in the field. The 77 grain TMK is engineered to seat to an overall cartridge length that allows loading into M16/AR15 magazines, offering exceptional versatility across a wide range of shooting platforms. Featuring a copper jacket and a sectional density of .219, these bullets provide outstanding consistency shot after shot. This bullet requires a barrel twist rate of 1x8" or faster and is sold in a generous 500-count box.
