Sierra 4320C Gameking 6.5Mm 120Gr 500/Box
$204.99
The Sierra 4320C Gameking 120-grain 6.5mm bullet is a versatile projectile engineered for hunters and reloaders working with popular mid-range cartridges. Introduced in 2023, this 120-grain Gameking delivers the controlled expansion and penetration the Sierra TGK line is known for, making it a solid choice for deer, hog, and medium-game hunting across multiple platforms—whether you're running a 6.5 Grendel AR, a bolt-action rifle, or stepping up to larger 6.5 cartridges like the Creedmoor or 260 Remington.
What sets the 120 TGK apart is its ballistic coefficient of .466 (G1), which translates to a flatter trajectory and less wind deflection downrange than lighter alternatives. Sierra's reputation for reliability shows up here too: this bullet is designed to expand predictably while maintaining penetration—essential when hunting tougher game or pushing into vermin work on coyotes and similar medium-sized predators. At recommended velocities around 2800 fps for deer-sized game, you get dependable terminal performance without excessive velocity demands on your cartridge.
The 500-round box gives reloaders volume to work with for load development and season prep. Whether you're hand-loading for precision hunting or stocking up for range days, the 4320C is a no-nonsense bullet backed by Sierra's long track record in the field and at the bench.
