While they are recognized around the world for record-setting accuracy MatchKing and Tipped MatchKing bullets are not recommended for most hunting applications. Although MatchKing and Tipped MatchKing 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. The #1380 was introduced in 1984. This bullet requires a barrel twist rate of 110in or faster.
