S&B 303BRITISH 180GR FMJ 20/400

Description

Sellier & Bellot’s .303 British load in 180-grain Full Metal Jacket configuration is straightforward range and training ammunition for shooters who still run Lee-Enfields, sporterized MkIII rifles, or any other firearm chambered for this century-old British service cartridge. The .303 British remains a viable choice for paper punching and practice, and having a consistent, economical FMJ load matters when you’re putting rounds downrange regularly.

The FMJ bullet construction uses a lead core enclosed in a CuZn 10 gilding-metal jacket. That hard outer jacket prevents deformation on impact, which keeps the bullet from expanding — useful for training because the terminal behavior stays predictable, and the smooth profile feeds reliably through the magazine-fed actions common to .303 rifles. The non-expanding design also means no barrel leading, which simplifies post-range cleaning.

Sellier & Bellot loads this ammunition in boxer-primed brass cases, which makes the spent brass worth keeping if you reload. The cartridge is new production and non-corrosive, so standard cleaning procedures apply — no need for the aggressive bore scrubbing that surplus corrosive-primed .303 demands. With a muzzle velocity of 2,477 fps and muzzle energy of 2,452 ft·lb measured from a 23.5-inch test barrel, the load performs where you’d expect a full-power .303 British to perform. Each box contains 20 rounds.

Sellier & Bellot has been producing ammunition since 1825 and is part of the CBC/Magtech group, giving the operation significant manufacturing depth. This is a practical, no-frills option for anyone who shoots a .303 and wants consistent brass-cased ammunition without surplus-market uncertainty.
