Sierra GameKing .224 55gr Full Metal Jacket Boat Tail
The Sierra GameKing #1355 represents a proven design that has served shooters since 1985. This 55-grain Full Metal Jacket Boat Tail bullet combines military-grade construction with hunting versatility.
Design and Construction
The boat tail configuration is the hallmark of this bullet. The streamlined tapered base significantly reduces aerodynamic drag, resulting in:
- Higher retained velocity downrange
- Greater striking energy at distance
- Flatter trajectory
- Reduced wind drift
The exceptionally heavy full metal jacket ensures reliable feeding in semi-automatic platforms while protecting the core. A properly located cannelure allows secure crimping for consistent performance.
Ideal Applications
This bullet was specifically designed to duplicate the military M193 specification, making it an excellent choice for:
- AR-15 and M16 platforms — engineered for reliable feeding and performance
- Ruger Mini-14 rifles — proven accuracy and function
- Varmint hunting — preserves pelts with minimal damage
- Small game — controlled expansion characteristics
- .22 centerfire handguns — non-expanding design minimizes pelt and meat damage
Loading Recommendations
Load to medium velocities for optimal performance. This approach prevents tumbling upon impact and maximizes the bullet's pelt-preservation characteristics. The design is particularly valued by trappers and pelt hunters seeking to minimize collateral damage while maintaining reliable terminal performance.
