Sierra GameKing Features The Sierra GameKing bullet is a jacketed lead boat tail projectile sized to .308 inch at 180 grains for use in .30 caliber rifle cartridges. The boat tail base shape reduces aerodynamic drag compared to a flat base design which helps the bullet retain velocity further downrange and resist the effects of crosswinds during flight. A synthetic tip integrated into the bullet s design further improves the ballistic coefficient and overall aerodynamics while also initiating more consistent and controlled expansion on impact. Sierra engineers the GameKing line specifically around a combination of penetration and expansion suited to medium and heavy game animals within its caliber range. This 500 count box gives handloaders enough projectiles to work up a hunting load test it extensively and still have a substantial supply left for the field. The jacketed lead construction keeps the bullet compatible with standard reloading dies and presses without requiring specialized equipment. Hunters who load their own .30 caliber ammunition rely on the GameKing s reputation for consistent accuracy and reliable terminal performance on game. For reloaders building precision hunting ammunition in .30 caliber the Sierra GameKing Tipped bullet is a proven choice.
