Sierra 6.5mm/.264 Caliber 140-Grain Tipped GameKing Bullets - 500 Count Box

The Sierra 6.5mm 140-grain Tipped GameKing is a purpose-built hunting bullet designed for the modern generation of 6.5 cartridges, especially those with 1-8 twist rates that can really stabilize it. If you're reloading for popular rounds like 6.5 Creedmoor, 6.5 PRC, or similar speedier 6.5s, this is the bullet Sierra designed with you in mind. The polymer tip enhances expansion on impact while the thick jacket controls penetration, making it a capable performer on game ranging from whitetail up through elk and bear. This is the real-world versatility modern hunters are after—one round for multiple applications in a single season.

The 140-grain weight sits in that sweet spot for 6.5 caliber hunting. It carries enough mass for deep penetration and energy retention on larger game, yet remains aerodynamic enough for the flatter trajectories these newer cartridges are known for. The sectional density of 0.287 helps it drive straight through, resisting deflection on angled shots—something that matters when you're in the field and the animal isn't standing broadside.

This box contains 500 bullets, enough for a serious reloading session or an entire season of hunting loads. Whether you're a precision handloader fine-tuning loads for a new rifle or you've been at the bench for years, Sierra's quality and consistency keep velocity spreads tight and groups tight. Just remember: this bullet demands a 1-8 twist rate or faster. Slower twists won't stabilize it properly, and an unstable bullet downrange is a dangerous waste of time and ammo.
