The Sierra GameKing .375 caliber 300 grain Spitzer Boat Tail (SBT) bullet is a precision-engineered projectile intended for large-game and magnum-class rifle applications. Sierra forms the jacket using a heavy cup and a four-station draw to produce consistent dimensions, and inserts a hard 3% antimony lead alloy core for controlled performance. This bullet is designed especially for the .375 H&H Magnum and is used in comparable high-powered cartridges where retained weight, penetration, and ballistic efficiency are required.
