Description
This is straightforward ammunition made for anyone who shoots .303 British rifles regularly. Sellier & Bellot has been making quality ammunition since 1825, and this load carries that tradition forward with practical, dependable performance.
The 180 grain full metal jacket bullet is designed to cycle smoothly through most .303 rifles and provide the kind of consistent accuracy you need for zeroing scopes or honing your marksmanship at the range. The FMJ construction keeps things simple and effective, with a lead core backed by a copper jacket that handles the pressures without complaint.
Brass cases built for reloading
Each round uses a non-corrosive, boxer-primed brass case that handles reloading well. That matters if you shoot regularly. The brass isn't so brittle that it splits after a single firing, and plenty of dedicated reloaders appreciate having quality once-fired cases to work with. Muzzle velocity runs around 2438 fps with about 2376 foot-pounds of energy at the muzzle, which is typical for factory .303 British loads and pairs well with the 180 grain weight.
What to expect at the range
Rifles fed this ammunition tend to run without hiccups. The rounds feed cleanly, eject reliably, and don't produce excessive fouling. Real-world testing shows 3 to 4 inch groups at 100 yards from quality .303 rifles like Lee-Enfields, which is perfectly acceptable performance for practice and general shooting. Recoil stays gentle and consistent, which makes extended range sessions manageable even with rifles that have seen some age.
Made to military specs
Sellier & Bellot produces this ammunition in the Czech Republic to military specifications, and the parent company now includes CBC and German ammunition producer MEN, putting this in the hands of experienced manufacturers. Each box contains 20 rounds packaged simply and clearly marked.
