The .25 Caliber (.257) 117 grain Spitzer Boat Tail GameKing bullet stands as a testament to their commitment to excellence. Engineered with meticulous attention to detail, this projectile is crafted using Sierra's proprietary four-station jacket draw process—a method that ensures maximum concentricity and uniformity in each bullet produced.

This particular round boasts features that make it an ideal choice for medium game hunting at distances ranging from 200 to 500 yards.

These figures underscore the bullet’s ability to retain energy and trajectory integrity across various ranges.
