The Sierra 6.5mm 120-grain Tipped GameKing (TGK) bullet is a versatile hunting and varmint round built for shooters reloading in 6.5 Grendel, 6.5 Creedmoor, .260 Remington, 6.5×55 Swede, and similar mid-range cartridges. Introduced in 2023, this 120-grain rifle bullet combines a ballistic coefficient of .466 (G1) with the controlled-expansion performance that made Sierra's GameKing line trusted by hunters and precision shooters. Whether you're handloading ammunition for deer, hog, or medium game at moderate velocities, or pushing it downrange on coyotes and smaller varmints, the 120 TGK delivers the flat trajectory and reliable terminal performance you need in the field.
With a proven track record among Sierra Team shooters—both AR platform and bolt-action enthusiasts—this bullet is engineered for consistent accuracy and dependable expansion across a range of 6.5 cartridges. The tipped design and jacketed construction ensure that expansion is predictable and penetration adequate for your intended game, without the guesswork of older, untipped alternatives. The .466 BC means less wind deflection and velocity drop over distance, keeping your shots on target even when conditions aren't perfect.
Reloaders working with the 6.5 Grendel should note the recommended maximum velocity ceiling of 2,800 fps for deer and medium game, ensuring you stay within safe and ethical performance parameters. The 100-round box gives you enough bullets to work up loads, test your accuracy, and stock your magazine with confidence. If you're assembling rifle ammunition for hunting or extended range work, the Sierra 120-grain TGK rounds out your options in the increasingly popular 6.5 caliber space.
