Those are the four principles that are the foundation Atomic Ammunition has built their company on. Over the last several years Atomic Ammunition has conducted an extensive due diligence processes to come up with proprietary loadings for rifles and self-defense pistols. They utilized three of the most renowned independent test laboratories in the United States to reconfirm their findings and the safety of each load.

MatchKing rifle bullets are super-accurate bullets with very thin jackets and are held to exacting tolerances in diameter and weight. Their accuracy has been acclaimed worldwide and they have been used to win more target competitions than all target bullets from other manufacturers combined. Weight retention is held to within +/- 0.3 grain.  Sierra has enhanced a segment of the MatchKing line by adding the acetal resin tip, thus crowning the Tipped MatchKing (TMK) bullet line. The major advantage of adding a tip to the bullet is the reduction of drag, producing a more favorable ballistic coefficient. The Tipped MatchKing (TMK) bullet is an excellent choice for Palma and F-Class (FTR / F Open) matches, as well as 3-Gun and various other competitions.  Another benefit is reliable feeding in magazine fed firearms.

Although the MatchKing line is recognized around the world for record setting accuracy, like their untipped counterparts, Tipped MatchKing (TMK) bullets are not recommended for hunting anything larger than varmints.  Having heavier jackets than the Hornet or Blitz line of bullets, these bullets will not provide the same explosive expansion on small varmints.
