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 of match bullets.
This bullet was developed after extensive research and a year and a half of testing by Sierra, and it exemplifies our commitment to quality and performance of our products. The jacket of this bullet is formed from the heaviest Sierra cup through Sierra's unique four-station draw to very precise dimensions. A very hard 3% antimony lead alloy core is inserted, and the bullet is given the classic Sierra SBT shape. Designed especially for the 375 H&H Magnum cartridge, this bullet has excellent expansion and deep penetration on heavy game at all ranges for a wide variety of hunting situations. Sierra has received many reports of 5-shot groups at 100 yards that measured less than half an inch extreme spread! An exceptionally high ballistic coefficient and smashing down-range performance combine to make this an ideal bullet in a 375 H&H Magnum or 378 Weatherby Magnum for the largest game on the North American continent and for heavy thin-skinned African game.
The streamlined tapered base of the boat tail bullet greatly reduces drag, which results in higher retained velocity, greater striking energy, a flatter trajectory and less wind drift than comparable flat base bullets.
