The Sierra GameKing 1625 is a .25 Caliber (.257) 100‑grain Spitzer Boat Tail reloading bullet sold in boxes of 100. Its boat‑tailed design reduces aerodynamic drag to help retain velocity and reduce wind drift at extended ranges. The bullet uses a lead core with a copper jacket produced via Sierra’s multi‑station jacket draw process for consistent concentricity and accuracy. Sectional density is listed at .216, and the GameKing series is positioned for hunting and longer‑range shooting applications.
