HSM Game King 300 Remington Ultra Magnum Spitzer Boat Tail 180 Grain 20 Rounds

The HSM 300RUM13N Game King 300 RUM 180 gr Sierra GameKing Spitzer Boat Tail ammunition delivers the sort of downrange performance hunters and long-range shooters demand from 300 Remington Ultra Magnum loads, with the Sierra GameKing Spitzer Boat Tail design offering a flat trajectory and excellent ballistic coefficient for tighter groups at extended ranges; the 180 grain weight provides a solid balance of velocity and retained energy for large game hunting, while the brass casing promotes reliable feeding and extraction in bolt-action rifles and magnum actions. In practical use, this round shines on open-country hunts where shots extend beyond typical hunting distances, on mountain stalks where wind-bucking bullets keep wind drift manageable, and at the range when tuning long-range zeroes or testing ballistic calculators; the GameKing series reputation for consistent external ballistics makes it straightforward to predict drop and windage for ethical, one-shot placements.
