The Sellier & Bellot .223 Remington 77gr HPBT Match Ammunition (Product Code: SBV342252) is engineered for long-range precision rifle shooting and benchrest competition. Loaded with a heavy 77-grain (5.00-gram) Hollow Point Boat-Tail projectile, this cartridge provides superior aerodynamic efficiency and wind resistance compared to standard 55gr or 62gr factory loads. It features a CuZn 10 tombac jacket, standard boxer-primed reloadable brass casings, and non-corrosive primers for consistent ignition.

Key Features

• Match-Grade Boat-Tail Projectile: Utilises a 77gr HPBT bullet with a high G1 ballistic coefficient of 0.376 (G7 = 0.193) to reduce drag and maintain supersonic stability at extended distances.
• High Muzzle Energy: Produces a factory-rated muzzle velocity of 861 m/s (2,825 fps) and 1,853 J (1,364 ft·lb) of muzzle energy from a standard 20-inch (51 cm) test barrel.
• Quality Reloadable Components: Built with premium boxer-primed brass cases adhering to standard SAAMI .223 Remington dimensions, measuring 57.0 mm (2.244 in) in overall cartridge length.
• Long-Range Aerodynamics: Maintains flight stability and trajectory retention across practical target engagement distances ranging from 300 to 800 metres.

Who is the Sellier & Bellot .223 Rem 77gr HPBT 20 Pack for?

• Precision Rifle Competitors — Requires the aerodynamic efficiency of this .223 Remington match ammunition's 0.376 G1 ballistic coefficient to maintain trajectory retention and resist wind deflection across target distances from 300 m to 800 m.
• Sport Shooters with Fast-Twist Rifles — Delivers optimised gyroscopic stability and match-grade consistency when paired with modern rifle barrels featuring a 1:7" to 1:8" twist rate capable of fully stabilising the heavy 77-grain projectile at an initial velocity of 861 m/s.

Less suitable for: Rifles featuring slower twist rates such as 1:12" or 1:14", which fail to stabilise the 77-grain bullet and cause tumbling or severe accuracy loss; these setups require lighter 52gr to 55gr projectile ammunition instead.
