Sie 30Cal 180Gr Tgk 50/Box
The Sierra 30 Caliber 180 Grain Tipped GameKing rifle bullet is purpose-built for hunters stepping up to heavier game with .308 Winchester and .30-06 Springfield cartridges. Introduced in 2024, this projectile addresses a real need: proper chamber fit and consistent seating in these classic magnum platforms, paired with the terminal performance that comes with a true heavy-for-caliber bullet. If you're running a .300 Winchester Magnum instead, Sierra's #4680 is the better choice for your rifle—this is the ticket for .308 and .30-06 shooters.
The 180-grain mass is no accident. It delivers the penetration and accuracy you need when hunting elk, moose, or other large game, without forcing you into a specialized wildcat or overbore cartridge. The Tipped GameKing design combines Sierra's proven soft-point construction with a ballistic tip, giving you a flat trajectory downrange without sacrificing the controlled expansion that matters on game. With a G1 ballistic coefficient of 0.543, this bullet cuts wind drift and holds velocity better than lighter options in the same caliber, making it a genuine advantage on longer shots across varied terrain.
Each box contains 50 rounds, so you can load a full season's worth of hunting ammo or develop loads for both .308 and .30-06 rifles without multiple purchases. The jacketed lead core and consistent construction from Sierra's equipment means you'll get repeatable velocities and tight groups once you dial in your load.

Frequently Asked Questions
Will these bullets work in my .300 Winchester Magnum?
No—Sierra designed these specifically for .308 Winchester and .30-06 Springfield. If you're running a .300 Win Mag, use Sierra's #4680 bullet instead, which was engineered for that cartridge.

The 180-grain bullet represents a true heavy-for-caliber option that delivers superior penetration and game performance on elk and moose without requiring a specialized cartridge or magnum action. The weight combines with the Tipped GameKing design to provide both flat trajectory and controlled expansion on impact.
Can I use these for long-range target shooting?
Yes—the 0.543 G1 ballistic coefficient and consistent construction from Sierra make these bullets suitable for both hunting and precision rifle applications. The ballistic tip and heavy weight help maintain velocity and trajectory at distance.
How many bullets are in a box?
Each box contains 50 bullets, giving you enough to load a full season of hunting ammunition or conduct comprehensive load development for your .308 or .30-06 rifle.
