The Sellier & Bellot .300 Winchester Magnum 168 Grain Hollow Point Boat-Tail (HPBT) Match Rifle Ammunition (model V341662) is engineered for precision benchrest and long-range sport shooting. Delivering a muzzle velocity of 3,018 fps (920 m/s) and a muzzle energy of 3,398 ft·lb (4,613 Joules) from a 23.5-inch (600 mm) test barrel, this factory-loaded cartridge provides flat trajectories and predictable downrange flight for consistent shot grouping.

Key Features

• Match-Grade Aerodynamic Profile: The 168-grain HPBT projectile design minimizes aerodynamic drag with a G1 ballistic coefficient of 0.458 (G7 = 0.231), maintaining supersonic flight past 400 yards at 2,232 fps.
• Factory-New Reloadable Cases: Built with high-uniformity, boxer-primed brass cases and non-corrosive propellants suitable for precision handloading.
• Barrel Twist Compatibility: Optimised for target rifle barrels with a 1:10" to 1:11" twist rate.
• Standard Overall Length: Measures 3.339 inches (84.8 mm) in cartridge overall length for reliable cycling and chambering in standard .300 Win Mag chambers and magazines.

Who is the Sellier & Bellot 300 Win Mag 168 Grain BTHP Match Ammo for?

• Long-range precision benchrest sport shooters — Drives a high initial muzzle velocity of 3,018 fps paired with 3,398 ft·lb of muzzle energy, giving this 300 Win Mag match ammunition the speed required for flat trajectories between 100 and 800 metres.
• Target shooters demanding match-grade projectile consistency — Employs a 168 grains hollow point boat-tail bullet with an aerodynamic G1 ballistic coefficient of 0.458 to minimize wind drift and sustain shot-to-shot consistency in 1:10" to 1:11" twist barrels.

Less suitable for: Terminal medium-to-large game hunting, where thin-jacketed HPBT match bullets risk premature fragmentation on bone rather than controlled expansion (demanding dedicated hunting-specific rounds with expanding soft point or bonded projectiles), or extreme long-range competition beyond 1,000 metres, where heavier 190-grain or 220-grain match ammunition is required to provide higher ballistic coefficients that resist wind drift.
