For shooters running Lee-Enfield rifles, Ishapore conversions, or other .303 British platforms, the Sellier & Bellot 180-grain Full Metal Jacket offers a clean-feeding, brass-cased load engineered for range sessions and function drills. Sellier & Bellot has manufactured cartridge ammunition since 1825 in the Czech Republic, now operating under the CBC/Magtech group alongside MEN of Germany. This 303 British load delivers 2438 feet per second and 2376 foot-pounds of muzzle energy from a flat-base FMJ bullet seated in non-corrosive, boxer-primed brass — reloadable and suitable for mil-spec chambers.
Performance at a Glance
The 180-grain projectile uses a full metal jacket with a flat base, which improves feed reliability in worn military-spec chambers and reduces deformation on impact — a design originally intended for furbearer hunting and competitive shooting with historic rifles. Sellier & Bellot brass is drawn to accept large rifle primers (boxer configuration) and can be resized, trimmed, and reloaded for shooters who maintain their own brass stock.
