The Sierra MatchKing .338 caliber 250 grain Hollow Point Boat Tail (HPBT) is a purpose-built match bullet intended for precision use in magnum rifle cartridges. It is manufactured to MatchKing standards and is noted for a high ballistic coefficient that supports long-range consistency. Sierra cites reliable performance in magnum cartridges such as the 338 Winchester Magnum and the 338-378 Weatherby. These bullets are reported to shoot well in 338 Winchester Magnum barrels with a 1:12″ twist rate.
MatchKing and Tipped MatchKing bullets are engineered for target and competition use; they are not recommended by the manufacturer for most hunting applications where rapid, controlled expansion is required. For varmint work, Sierra notes lighter-jacketed designs like Hornet Blitz or Varminter as alternatives for more reliable expansion at comparable velocities.
