The Sierra GameKing 25 Cal 100 Grain Spitzer Boat Tail is a precision rifle bullet designed for reloaders pursuing medium game and varmints with accuracy and reliable performance at distance. Built on Sierra's reputation for concentricity and uniformity, this 100-grain spitzer boat tail rounds out a capable cartridge offering for hunters who want match-grade components and predictable expansion downrange.
GameKing bullets are engineered for the shooter who refuses to compromise on accuracy or terminal performance. Sierra's four-station jacket draw process creates jackets with exceptional concentricity and uniform taper dimensions—the kind of precision that translates to tighter groups and more consistent ballistics from round to round. The boat tail design improves aerodynamic efficiency, which matters when your shots stretch beyond 200 yards and external ballistics start to matter as much as powder charge.
The 100-grain weight in .25 caliber strikes a practical balance for medium game hunting and serious varmint work. This bullet responds well across a spectrum of velocities, but shooters will find it performs best when ranges exceed 200 yards, where the boat tail geometry and aerodynamic design shine. Reloaders appreciate GameKing bullets for their dimensional consistency and the confidence that comes from knowing each component meets the same tight tolerances. Whether you're fine-tuning a handload for a specific rifle or building ammunition for multiple platforms, the uniformity built into Sierra's manufacturing process takes the guesswork out of component selection.
