S&B 338LAPUA 300GR SIERRA 10/100

Description

Sellier & Bellot’s .338 Lapua Magnum Match load is built around the Sierra MatchKing hollow point boat-tail bullet, a projectile that has earned its reputation in long-range competition through dimensional consistency and high ballistic coefficients rather than marketing. At 300 grains, this bullet carries enough sectional density to resist wind deflection and retain velocity at distances where lighter projectiles have already shed meaningful energy. The boat-tail base reduces aerodynamic drag at the rear of the bullet, which helps maintain a stable, predictable trajectory as the round transitions from supersonic to the ranges where .338 Lapua Magnum is most often stretched.

Sellier & Bellot loads this ammunition to match-grade standards, meaning case dimensions, powder charges, and primer seating are held to tight tolerances to keep muzzle velocity consistent from round to round. That consistency matters more at distance than at the bench: a variance of even 20 fps translates to a meaningful elevation shift at 800 or 1,000 yards. Brass cases are Boxer-primed and reloadable, which makes a difference to the serious long-range shooter who wants to recover and resize fired brass for handloading once the factory load has served its purpose.

Muzzle velocity out of a 27.25-inch test barrel is 2,713 fps, generating 4,903 ft-lbs of energy at the muzzle. Shooters running shorter barrels should expect modest velocity losses below those figures. This load is suited to precision rifle competition, long-range target work, and hunters pursuing large or dangerous game at extended distances. Sold in boxes of 10 rounds.
