This heavy bullet has Sierra's classic spitzer boat tail shape for high ballistic coefficient and high ballistic efficiency downrange. It delivers accuracy well under one minute of angle. This bullet has an extremely heavy double-tapered jacket and an extremely hard core for absolute control of expansion on heavy game. It is suitable for all North American big game from elk and moose to the large and dangerous Kodiak bear and suitable for all large thin-skinned African game in rifles firing the 375 H&H Magnum cartridge. The excess velocity of maximum loads in the 378 Weatherby Magnum cartridge makes this bullet too light for close range and dangerous game. However loaded to the correct velocity levels this bullet has proven itself in the game fields around the world.
