Sierra 7mm 180 Gr MatchKing Bullets 500 Ct The 7mm 180 grain HPBT MatchKing was created in response to requests from top-level F-Class shooters. Sierra has designed these MatchKingA(R) bullets to provide a higher weight/higher B.C. alternative in our 7mm line. This bullet's 12 caliber secant ogive and lengthened boat tail make it the perfect choice for the discerning 7mm long range shooter.While they are recognized around the world for record-setting accuracy, MatchKingA(R) and Tipped MatchKingA(R) bullets are not recommended for most hunting applications. Although MatchKingA(R) and Tipped MatchKingA(R) bullets are commonly used for varmint hunting, their design will not provide the same reliable explosive expansion at equivalent velocities in varmints compared to their lightly jacketed Hornet, Blitz or Varminter counterparts. This bullet requires a barrel twist rate of 1A-8" or faster.
