The Sellier & Bellot .303 British 180 Grain FMJ Ammunition is manufactured specifically for target shooting, historic service rifle matches, and marksmanship training. Featuring a 180-grain (11.70 g) Full Metal Jacket projectile with a CuZn 10 alloy jacket and a lead core, this factory load is engineered for consistent cycling and minimal barrel fouling in classic military bolt-action rifles. It uses standard reloadable brass cases fitted with non-corrosive Boxer primers and adheres strictly to C.I.P. rimmed cartridge specifications.

Key Features

  • Target-Grade FMJ Projectile: Utilises an enclosed base 180-grain Full Metal Jacket bullet (projectile reference No. 2909) to prevent bore leading during sustained range sessions.
  • Consistent Ballistics: Delivers a muzzle velocity of 755 m/s and 3,335 Joules of muzzle energy from a standard 600 mm test barrel.
  • Aerodynamic Flight Profile: Offers a G1 ballistic coefficient of 0.506 (G7 of 0.255) and a sectional density of 0.266 lb/in² for stable trajectory across standard 100 to 600+ yard target distances.
  • Reloadable Factory Brass: Constructed with non-corrosive Boxer-primed brass cases adhering to standard C.I.P. dimensions for reliable feeding and case life for handloaders.
  • 50-Round Packaging: Packed in 50-round boxes, weighing approximately 1.34 kg unboxed, suited for extended range days and competition stages.

Who is the Sellier & Bellot .303 British 180 Grain FMJ Ammo for?

  • Historic service rifle match competitors — relies on a factory 180-grain FMJ bullet generating 3,335 Joules of muzzle energy to replicate traditional military service trajectory profiles in vintage bolt-action platforms.
  • Lee-Enfield rifle target shooters — uses standard 50-round packaging and an enclosed-base bullet launching at 755 m/s to minimise bore fouling and maintain consistent chamber pressures during high-volume range training.

Less suitable for: Medium-to-large game hunting due to the non-expanding 180-grain FMJ projectile, or for non-.303 British firearms (strictly incompatible with .308 Win / 7.62x51mm and .30-06 chambers); hunters require dedicated expanding soft-point hunting ammunition, while non-.303 owners require cartridges matched to their rifle's specific chamber calibre.
