Sierra GameKing Rifle Bullets .323 cal .323" 220 gr SBT 50/ct

Sierra GameKing Rifle Bullets .323 caliber 220 grain Spitzer Boat Tail (SBT) ammunition is purpose-built for the 8mm Remington Magnum and represents a proven choice for hunters pursuing North American big game and African plains species. The 220-grain bullet weight delivers the ballistic performance and terminal energy required for ethical, deep-penetrating shots on large-frame game where oversized bore diameters demand specialized projectiles matched to rifle-specific chamber dimensions.

Construction features a heavy double-tapered jacket engineered for controlled, deep penetration through dense muscle and bone. The Spitzer Boat Tail design optimizes ballistic coefficient and long-range velocity retention, critical factors when hunting at extended distances where velocity loss and wind deflection are measurable concerns. The .323-inch bullet diameter is caliber-specific—verify your rifle is actually bored for .323-inch ammunition before purchase, as confusion with neighboring 8mm specifications can result in dangerous pressures or poor accuracy. Sierra's GameKing line has established a reputation for consistent expansion and reliable weight retention across varying impact velocities.

This 50-round count package suits hunters who load for magnum rifles chambered in 8mm Remington Magnum or similar cartridges where ammunition availability is limited and reloading is standard practice. Shooters handloading for long-range or dangerous-game applications will appreciate the bullet's heavy construction and proven field performance. The boat tail configuration also provides advantages for shooters developing precision loads, as it supports tighter velocity spreads and improved downrange accuracy in comparison to flat-base projectiles of equivalent weight.
