GameKing Bullets are designed for hunting at long range, where their extra margin of performance can make the critical difference. GameKing bullets feature a boat tail design to bring hunters the ballistic advantage normally found with match target bullets. The 338 Caliber 250 Grain GameKing is an accurate, devastating large game bullet designed for the 338 Winchester Magnum. It is a popular choice for hunters going after Elk, Mule Deer, Alaskan Moose, and African plains game.
