Sierra Tipped GameKing Features The Sierra Tipped GameKing bullet in 30 Cal was introduced to give .308 and .30-06 shooters a better chamber fit than earlier heavy bullet offerings. Its jacketed lead construction and polymer tip combine to provide excellent penetration and accuracy on big game while the .543 G1 ballistic coefficient and .264 G7 ballistic coefficient keep velocity and energy retention high at extended ranges. The 180 grain weight and .308 diameter were specifically matched to proper seating depth in both popular 30 caliber cartridges. Hunters pursuing heavier game benefit from the added mass and controlled expansion this bullet is built to deliver. Each box ships with 50 bullets giving handloaders enough material to develop and test a load before committing to a hunting season. The tipped profile improves feeding and initiates expansion reliably on impact which matters when shot placement on big game is not always perfect. Reloaders working up loads for 308 Winchester or 30-06 Springfield rifles will find this bullet suited to both since it was designed around their shared chamber dimensions. For shooters running a 300 Win Mag Sierra recommends its companion 4680 bullet instead underscoring how purpose built this 4681T offering is for its intended cartridges.
