The Sellier & Bellot .308 Winchester 175 Grain HPBT Match Rifle Ammunition (20 Rounds) is precision-engineered target ammunition designed for medium- and long-range shooting disciplines. Loaded with a 175-grain Hollow Point Boat-Tail projectile featuring a CuZn 10 gilding metal jacket and lead core, this cartridge is tuned to maintain aerodynamic stability and resist wind drift over extended distances. Testing from a standard 600 mm (23.6-inch) proof barrel yields a muzzle velocity of 800 m/s (approximately 2,625 fps) and a muzzle energy of 3,632 J, producing a flat trajectory with published manufacturer drop tables extending to 1,000 metres.

Key Features

• Aerodynamic Match Bullet: Incorporates a 175-grain Hollow Point Boat-Tail (HPBT) projectile with a G1 ballistic coefficient of 0.474 and G7 of 0.239 for sustained supersonic velocity.
• Factory Ballistics: Delivers a muzzle velocity of 800 m/s and 3,632 J of energy at the muzzle out of a 600 mm test barrel.
• Reloadable Components: Built with quality Boxer-primed, non-corrosive CuZn 30 brass cases suitable for precision handloading.
• Standard Chambering: Manufactured to an overall cartridge length (OAL) of 71.10 mm to ensure reliable feeding and fit in standard .308 Winchester and 7.62×51mm chambers.

Who is the S&B Sellier & Bellot 308 Win 175 Grain Hpbt Match Ammo 20 Rd for?

• Precision rifle and tactical competition shooters — requires a projectile with a G1 ballistic coefficient of 0.474 and a muzzle velocity of 800 m/s to minimise wind deflection and maintain consistent target engagement across intermediate and extended stages using this .308 Winchester match ammunition.
• F-Class and benchrest target shooters extending past 800 metres — relies on the 175-grain bullet weight stabilised through 1:11" to 1:12" barrel twists to remain supersonic and prevent the early transonic tumbling typical of lighter 147–150 grain factory ammunition when shooting out to 1,000 metres.

Less suitable for: Game hunting or humane culling, as the non-expanding match hollow point projectile does not provide controlled terminal expansion; dedicated soft-point, tipped, or bonded expanding hunting ammunition is required. It is also unsuitable for rifles with slow rifling twist rates of 1:13" or slower, which fail to properly stabilise heavy 175-grain projectiles and require lighter 150- to 168-grain loads instead.
