This bullet is designed in the MatchKing® tradition and intended for rifles shooting magnum cartridges, such as the 338 Winchester Magnum and 338-378 Weatherby. 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 VarmintKing counterparts. Please Note!! The #9300 bullet requires at least a 1×10″ twist barrel
