Norma Match King ammunition in .338 Norma Magnum (brand part no. 20185272) loads a 300-grain open-tip match bullet built specifically around the cartridge that was designed to shoot it. The .338 Norma Magnum was engineered from a clean slate to fire a 300-grain Sierra MatchKing bullet with the best possible accuracy and the highest velocity achievable while keeping the loaded round at 3.68 inches or less, so the case and the bullet were built as a matched pair from day one. The open-tip match design keeps the bullet’s jacket thin and uniform for extreme long-range consistency rather than for hunting-style expansion. For .338 Norma Magnum shooters who want the cartridge running the bullet it was purpose-built around, this rifle ammunition is the factory answer.
