Sellier & Bellot Rifle Line .303 British 180 Grain Full Metal Jacket (MPN: SB303A)
Owners of military surplus Lee-Enfield rifles, Pattern 1914 bolt-actions, and classic sporting arms in .303 British face a frequent challenge: finding consistent, non-corrosive factory target loads that mirror original military ball trajectories without causing sticky extraction in aged chambers. Sellier & Bellot engineered their Rifle Line 180-grain Full Metal Jacket (FMJ) loading specifically to resolve this issue. Engineered to vintage military specification standards, this load provides shooters, collectors, and surplus enthusiasts with smooth chambering and dependable accuracy without the barrel-corroding risk of old cordite surplus ammo.
Produced in Europe under strict CIP commercial guidelines, each round features Sellier & Bellot's heavy 180-grain full metal jacket projectile. The bullet’s smooth gilding metal jacket and balanced lead core ensure uniform barrel engagement and stable flight out of traditional multi-groove and Enfield-rifled barrels. S&B seats these heavy-for-caliber projectiles in factory-new, heavy-walled brass cases charged with temperature-stable propellants and non-corrosive boxer primers, making them an excellent choice for target shooters who re-prime and reload their brass.
On the range, expect authentic vintage military ballistic performance with consistent point-of-impact alignment on military ladder sights. Pushing a muzzle velocity right around 2,438 FPS, this 180-grain load generates stable flight paths and manageable felt recoil out of heavy steel actions. The smooth-rimmed brass case ensures positive extractor hook engagement and effort-free ejection across both SMLE turn-bolt actions and commercial hunting rifles alike, making every shooting session reliable and enjoyable.
Armorer Bench Notes & Technical Maintenance Guidance
Shipping Restrictions: Ammunition sales are strictly regulated. Check all state and local laws prior to ordering. Cannot ship to PO Boxes, APO/FPO addresses, or internationally. Must ship via ORM-D / Hazardous Ground transport.
Armorer Tip: The .303 British is a rimmed cartridge designed to head-space on the case rim rather than the shoulder. When loading Lee-Enfield stripper clips or detachable box magazines, always ensure each round's rim is placed in front of the rim below it ("stagger-stacked") to prevent rim-lock during rapid bolt manipulation. Additionally, check vintage firing pin protrusion to ensure clean primer strikes without piercing boxer primers.
