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 150 Grain Full Metal Jacket GameKing was designed for use in semi-automatic 30 Caliber rifles. Its cannelure is placed to allow use for both 308/7.62 and 30-06 cartridges. Perfect for low to medium velocities where valuable pelts are to be preserved.
