The Sierra .224 55GR Blitzking 1455C is a specialized bullet designed for varmint and small game hunting. Here are key features and information about this bullet:

1. Bullet Type: The BlitzKing is designed for explosive expansion, making it particularly effective for varmints and small game.
2. Ballistic Coefficient: The bullet is engineered with an increased ballistic coefficient compared to a flat-base design. This characteristic enhances its aerodynamic efficiency, contributing to better long-range performance.
3. Accuracy: The bullet inherits accuracy characteristics from the MatchKing line, ensuring precise shot placement.
4. Nose Tips: The nose tips of these bullets are made of a proprietary acetyl resin compound. This material likely contributes to the bullet’s controlled expansion upon impact.
5. Boat Tail Design: The 55-grain #1455C variant features a boat tail design. Boat tails are known for further increasing the ballistic coefficient, which is beneficial for maintaining velocity and stability over longer distances.
6. Muzzle Velocity: The BlitzKing bullets in 22 caliber are designed to be fired at muzzle velocities up to 4400 fps. This indicates that they are suitable for high-velocity applications.
7. Packaging: It comes in a pack of 500 bullets, providing a substantial quantity for reloaders.
