The Sierra GameKing 270 Win .277 140gr HPBT bullets are engineered for hunters who demand both precision and reliable expansion in the field. These projectiles combine Sierra's proven accuracy foundation with hollow-point construction designed to deliver quick, consistent expansion on game. Each box contains 100 rounds of unloaded bullets—the reloading component itself, not factory-loaded ammunition—giving you the control to build loads tailored to your rifle and hunting conditions.
GameKing bullets feature a polymer tip that initiates expansion upon impact, paired with an optimized jacket wall thickness that controls how the bullet opens while retaining weight for deep penetration. The boat-tail design promotes stable flight downrange and supports the ballistic coefficient Sierra has engineered into the profile. This combination makes the GameKing suitable for medium to longer-range hunting where both accuracy and terminal performance matter.
Whether you're reloading for opening day or fine-tuning a new load, the .277 140-grain GameKing offers the consistency and performance characteristics that have made Sierra a trusted name among precision rifle shooters and hunters. The transparent tip provides visual confirmation of uniformity lot to lot, and the hollow-point cavity is sized to work across a realistic range of hunting velocities.
| Caliber | .270 Winchester (.277) |
| Weight | 140 grains |
| Bullet Type | Hollow Point Boat Tail (HPBT) |
| Count | 100 bullets |
| Product Type | Reloading component (unloaded bullets) |
Sierra GameKing bullets are the projectile component only—you'll need to reload them with powder, primers, and cartridge cases to create finished ammunition. This gives reloaders full control over velocity, accuracy, and performance tuning for their specific rifles and hunting scenarios.
Yes. The GameKing line is designed specifically for hunting applications, combining accuracy with controlled expansion and weight retention for ethical, reliable performance on game at field distances.
These .277 caliber bullets are designed for .270 Winchester rifles and other cartridges that use .277 diameter projectiles. Always verify compatibility with your specific cartridge and rifle before reloading.
The transparent polymer tip helps initiate expansion immediately upon impact, while the hollow-point cavity and jacket design control how rapidly the bullet opens. This combination is engineered to deliver expansion across realistic hunting velocities while maintaining sufficient weight retention for penetration.
