The Sellier & Bellot .338 Lapua Magnum Target Match ammunition (SKU: V340412 / SB338LMB) is engineered for precision rifle systems engaging targets at extended distances. Featuring a heavy 300-grain (19.40 g) Hollow Point Boat Tail (HPBT) projectile, this factory match load achieves a muzzle velocity of 2,713 fps (827 m/s) and a muzzle energy of 4,903 ft·lb (6,648 J) from a 690 mm test barrel. Built with high-grade reloadable brass, Boxer primers, and an aerodynamic profile delivering a G1 ballistic coefficient of 0.776, it provides the low drag and high sectional density necessary to maintain supersonic flight beyond 1,200 metres.

Key Features

• Heavy Match Projectile: Loaded with a 300 gr HPBT bullet offering a high 0.375 lb/in² sectional density for stability in flight.
• Aerodynamic Efficiency: Features a G1 ballistic coefficient of 0.776 and a G7 ballistic coefficient of 0.390 to minimise wind drift across extreme ranges.
• Consistent Internal Ballistics: Factory-charged in uniform reloadable brass cases using standard Boxer Large Rifle primers for reliable ignition.
• Standard Chamber Compatibility: Assembled to an overall cartridge length (OAL) of 91.80 mm (3.614 in), weighing 47.2 g per complete cartridge.
• Compact Packaging: Supplied in convenient 10-round retail boxes measuring 49 mm (L) × 101 mm (W) × 97 mm (H) with a total box weight of 0.52 kg.

Who is the S&B Sellier & Bellot 338 Lapua 300 Grain Bthp Match Ammo 10 Rd for?

• Extreme long-range target shooters — provides a high G1 ballistic coefficient of 0.776 that keeps this .338 Lapua Magnum match ammunition supersonic well past 1,200 metres when engaging targets past 1,000 metres.
• Precision rifle competitors — delivers a consistent 2,713 fps muzzle velocity paired with a heavy 300 gr projectile to minimise wind deflection during F-Class and ELR matches.
• Marksmen conducting long-range sniper training — relies on the 10-round box format and uniform 4,903 ft·lb muzzle energy output of this .338 Lapua Magnum cartridge for repeatable ballistic data gathering during training exercises.

Less suitable for: Rifles with barrel twist rates slower than 1:11", which fail to gyroscopically stabilise a heavy 300-grain projectile and require lighter 250-grain HPBT match loads; or target shooting under 300 to 400 metres, where intermediate calibres like .308 Winchester or 6.5 Creedmoor are better suited to prevent excessive recoil and running costs.
