Sierra: These bullets have been designed for the 338 Winchester Magnum cartridge. This 250 grain #2600 bullet also is ideal for the 340 Weatherby Magnum. Controlled, but reliable expansion and deep penetration are assured by an extra heavy double-tapered jacket in the 250 grain #2600 bullet, and hard core. The Sierra Spitzer Boat Tail shape assures a flat trajectory, minimum wind sensitivity and precise accuracy at long range for both bullets. Hunting rifles have shown extraordinary accuracy with this bullet in spite of the robust recoil of maximum loads. The 250 grain #2600 bullet has proven to be one of the finest 338 caliber hunting bullets in the world for heavy game. Whether the game is western elk or mule deer, Alaskan moose or bears, or African plains game, there simply is no better bullet for a magnum rifle in 338 caliber.
