Sierra Bullets .338 Caliber 300 Grain Hollow Point Boat Tail MatchKing Rifle Bullets. The huge 300 grain match bullet is a trendsetter. 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. Please Note The #9300 bullet requires at least a 1 10? twist barrel.
