.243 Caliber HPBT MatchKing Since its introduction several years ago, the 107 grain HPBT MatchKing bullet #1570 has been used successfully in a variety of competitive disciplines. This bullet has set new records and won national championships in such diverse competitions as National Match High Power and Silhouette. These competitions all have at least one requirement in common: extreme accuracy at long range. 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 18 or faster. Description: Diameter (inches) 0.243 Weight (grains) 107 Gr.
