Sako MatchKing .338 Lapua Mag 300gr

The Sako MatchKing .338 Lapua Magnum 300-grain (Sako part no. JASTRG338LM300B) pairs Sako’s precision factory loading with the Sierra MatchKing, one of the most trusted match bullets in long-range shooting. Built for consistency and a high ballistic coefficient rather than hunting expansion, this is a load for shooters demanding genuine extreme-range accuracy from a .338 Lapua Magnum rifle. .338 Lapua Magnum was purpose-built for military and precision competition use well past 1,000 yards, and Sako’s own reputation for accuracy makes this a natural factory pairing for shooters who don’t hand-load their own match ammunition.
