The Sierra GameKing Rifle Bullets .25 caliber .257" 117 grain SBT (Spitzer Boat Tail) is a precision projectile engineered for medium-game hunting at extended ranges. Sierra's proprietary four-station jacket draw process produces concentrically uniform jackets with controlled taper dimensions, delivering the accuracy and consistency demanded by hunters working 200 to 500-yard shooting windows. Each box contains 100 rounds, providing a practical supply for both practice and field deployment.
The 117-grain construction strikes a balance between sectional density and velocity in .25 caliber rifles, optimizing for reliable expansion without excessive fragmentation on medium-sized game. The spitzer profile minimizes drag coefficient, supporting flatter trajectories and retained energy at distance—critical factors when shooting beyond 300 yards where bullet drop and wind drift become decisive. The boat-tail design further improves ballistic coefficient, extending the effective range envelope for this bullet weight and caliber combination.
This ammunition is suited for precision reloaders and hunters fielding .25-06 Remington, .257 Roberts, and similar .25 caliber cartridges. The 100-count package supports both initial load development and field-ready inventory. Sierra GameKing bullets are commonly chosen by long-range rifle shooters who prioritize terminal performance consistency and want verified, repeatable ballistics data for trajectory calculation and point-of-aim adjustment at distance.
Handloaders appreciate Sierra's documented velocity and pressure data, which integrate with standard reloading software and ballistic calculators. Consistent jacket-to-core concentricity ensures minimal runout variance and repeatable flight characteristics—a measurable advantage for shooters building loads to sub-MOA precision standards.
