Sierra GameKing Features The Sierra GameKing 7mm bullet is built with a Tipped GameKing design combining a polymer tip with a jacketed lead core to deliver both aerodynamic efficiency and controlled terminal performance. At .284 inches in diameter and 180 grains this bullet is sized for standard 7mm cartridges commonly used in big game hunting applications. The tipped design initiates expansion more consistently than a traditional soft point helping ensure reliable performance across a range of impact velocities. A G1 ballistic coefficient of 0.632 and a G7 coefficient of 0.305 reflect the bullet s ability to retain velocity and resist wind drift at extended ranges. Sierra builds the GameKing line specifically for hunters pursuing big game balancing expansion and penetration to deliver effective terminal performance on larger bodied animals. The jacketed lead construction is engineered to hold together through heavy muscle and bone while still expanding to create a wound channel sufficient for quick ethical kills. This 100 count box gives reloaders enough projectiles to work up a hunting load and verify accuracy before heading afield. Sierra s reputation for consistency and accuracy makes the GameKing a trusted choice for hunters who demand dependable performance from their 7mm rifle.
