Sierra 4345C Tipped Gameking 6.5Mm 145Gr 500/Box
The Sierra 4345C Tipped Gameking 6.5mm 145-grain rifle bullets are designed for reloaders hunting modern cartridges that can stabilize them in a 1:8" twist barrel or faster. These polymer-tipped, boat-tail bullets combine Sierra's proven jacketing technology with a color-coded tip that enhances expansion on impact while maintaining reliable penetration across a range of game sizes—from whitetail to elk and everything in between. If you're hand-loading precision ammunition for medium to large game, these bullets deliver the balance of expansion and penetration that serious hunters demand.
Each box contains 500 bullets, making them economical for both load development and season-long hunting use. The polymer tip design is engineered to initiate expansion reliably while the thick copper jacket controls that expansion, preventing premature failure or over-penetration. This is the kind of predictable performance that separates good hunting loads from ones you'll actually trust in the field.
Sierra built these specifically for the newer generation of high-velocity 6.5mm cartridges that push bullets faster than traditional hunting rounds. The boat-tail design improves ballistic coefficient for flatter trajectories and retained energy downrange. Whether you're building match-grade ammo or hunting loads, this bullet gives you the component quality and consistency that comes from decades of Sierra's reloading expertise.

Frequently Asked Questions
What barrel twist do I need for the Sierra 4345C Tipped Gameking?
These bullets require a barrel twist rate of 1:8" or faster. If your rifle has a slower twist (1:9" or 1:10"), they may not stabilize properly, resulting in poor accuracy and unpredictable performance.
What game can I hunt with these 145-grain 6.5mm bullets?
Sierra designed these bullets for whitetail deer, elk, bears, and other medium to large game animals. The polymer tip and thick jacket work together to deliver expansion and penetration appropriate across that range of game sizes.
Are these bullets suitable for long-range hunting?
Yes. The boat-tail design improves ballistic coefficient, helping the bullets maintain velocity and energy downrange, which supports flatter trajectories and better performance at extended distances when loaded in modern high-velocity 6.5mm cartridges.
How many bullets come in a box?
Each box contains 500 Sierra 4345C Tipped Gameking bullets, giving reloaders a good supply for load development and season-long hunting ammunition production.
