The Sellier & Bellot .223 Remington 55gr SP (100 Bulk Pack) is factory-loaded centre-fire rifle ammunition manufactured in the Czech Republic for vermin eradication, hunting, and high-volume range work. Built with an exposed lead core and a drawn CuZn 10 tombac jacket (90% copper, 10% zinc), this semi-jacketed soft point bullet delivers controlled terminal mushrooming and reliable weight retention upon impact. Each round is assembled in a Boxer-primed, reloadable brass case with an overall length of 2.189 inches (approximately 55.6 mm). Fired from a 23.5-inch (600 mm) test barrel, the 55-grain projectile produces a muzzle velocity of 3,301 fps (1,006 m/s) and 1,330 ft-lb (1,803–1,822 Joules) of muzzle energy, making it an effective, flat-shooting load within 200 to 250 metres.

Key Features

• Controlled Terminal Expansion: Soft point construction combines an exposed lead tip with a CuZn 10 jacket to provide rapid mushrooming and deep penetration on small-to-medium game.
• High-Velocity Ballistics: Achieves a muzzle velocity of 3,301 fps with a 0.157 lb/in² sectional density and a G1 ballistic coefficient of 0.207 (G7: 0.102).
• Reloadable Brass Cases: Boxer-primed, high-grade brass cartridge cases allow for uniform cycling and subsequent handloading.

Who is the Sellier & Bellot 223 Rem 55gr SP 100 Bulk Pack for?

• Australian pest controllers — requires a fast-expanding 55-grain soft point projectile generating a muzzle velocity of 3,301 fps to ensure immediate dispatch on foxes and feral cats within 200 to 250 metres.
• Small-to-medium game hunters — benefits from 223 Remington soft point ammunition that delivers 1,330 ft-lb of muzzle energy and 689 ft-lb of retained energy at 200 yards for ethical harvesting of goats and small feral pigs.
• Shooters conducting live-fire training and field practice — uses this 100-round bulk pack format to run practical drills with factory-uniform, Boxer-primed ammunition without the premium cost of small-box hunting loads.

Less suitable for: Long-range shooting beyond 300 metres where velocity drops to 1,974 fps and energy falls to 476 ft-lb (heavier, higher-BC match or hunting bullets such as 69gr or 77gr HPBT projectiles suit better), or for large game such as red deer, large boar, and cattle (larger calibres like .243 Winchester or .308 Winchester suit better).
