The Sierra MatchKing .338 caliber 300 grain Hollow Point Boat Tail (HPBT) bullet is a heavy, high-performance match projectile designed for extreme long-range precision shooting. Featuring a streamlined profile, hollow point tip, and boat-tail base, it delivers an exceptionally high ballistic coefficient for superior stability, reduced wind drift, and consistent accuracy at extended distances. Commonly used in powerful cartridges like the .338 Lapua Magnum, it is favored by competitive shooters and long-range enthusiasts for its uniform construction and reliable performance, and is intended for target shooting rather than hunting.
