The Sierra 1845 GameKing delivers consistent terminal performance for medium to large game hunting with its proven 140-grain spitzer boat tail design. This .270 Winchester projectile combines accuracy with controlled expansion for clean, ethical harvests across varied hunting conditions.
What Makes This Different
Sierra's GameKing construction features a tapered jacket that's thicker at the base and thinner at the nose, creating predictable expansion while maintaining weight retention. The spitzer boat tail profile reduces drag and wind drift compared to flat-base bullets, extending effective range. Independent testing shows consistent sub-MOA groups in quality rifles with proper load development.
Key Features
- 140-grain weight optimized for .270 Winchester ballistics and game from deer to elk
- Spitzer boat tail design reduces wind drift and maintains velocity downrange
- Tapered jacket construction controls expansion while retaining 65-75% bullet weight
- Precision-drawn gilding metal jacket ensures consistent concentricity
- Lead core bonding prevents jacket separation during expansion
- 0.277-inch diameter with tight tolerances for consistent accuracy
- 100-count bulk packaging reduces per-round cost for serious hunters
Field performance data indicates reliable expansion at velocities between 1,800-3,000 fps, making this bullet effective from 25 yards to beyond 400 yards depending on rifle and load. The boat tail configuration maintains stability in crosswinds while the 140-grain weight provides sufficient sectional density for deep penetration on medium game. Sierra's quality control processes ensure each bullet meets dimensional specifications for consistent point of impact.
