Description
The .303 British cartridge has been feeding Lee-Enfields and other Commonwealth military rifles since the late 1800s, and this Sellier & Bellot load keeps that old warhorse cartridge relevant for today's hunters and surplus rifle owners. Sellier & Bellot has been making ammunition in the Czech Republic since 1825, making it one of the oldest continuously operating ammunition makers in the world, and that kind of longevity tends to show up in consistent, well built cartridges like this one.
Sellier & Bellot 150gr Soft Point Ballistics
This load sends a 150 grain semi-jacketed soft point bullet downrange at 2,654 fps, generating 2,346 ft-lbs of energy at the muzzle. The bullet uses a lead core with an exposed tip, so it mushrooms on impact instead of punching a clean hole straight through, which helps transfer energy to lighter and medium sized game like whitetail deer. At a bullet diameter of .311 inch and a sectional density of .222, it's built to the traditional dimensions the .303 British has always used, so it should feed and stabilize properly in Lee-Enfield barrels with their 1:10 twist rate.
Why This .303 British Load Works in Vintage Enfields
The brass cases are Boxer primed and non-corrosive, meaning you won't need to scrub the bore with hot water after a range session the way older military surplus ammo often demanded. That also means the cases can be reloaded if you're into handloading for your Enfield, though as with any rimmed .303 case, keeping fired brass matched to the rifle it was fired in and neck sizing rather than full length sizing will help extend case life. Reports from owners of No.1 and No.4 Enfields, along with sporterized and Lithgow rifles, tend to describe smooth feeding and function with this ammunition, which matters a lot in a rifle design that's well over a century old.
Twenty Rounds Ready for the Range or the Field
Each box holds 20 rounds, enough to check zero, run a few groups, or head out for an afternoon hunt without digging into a case. Whether you inherited a Lee-Enfield, picked one up as a surplus project, or just enjoy shooting a piece of history, this 150 grain soft point gives you a modern, reliable option in a caliber that can be tough to find on store shelves.

Frequently Asked Questions
What rifles is this .303 British 150 gr ammo made for?
This load is built to standard .303 British dimensions, so it's meant for Lee-Enfield No.1 and No.4 rifles, sporterized Enfields, Lithgow rifles, and other bolt actions chambered in .303 British. It uses the correct .311 inch bullet diameter that the caliber requires, unlike standard .308 inch projectiles.
Is this Sellier & Bellot .303 British load good for hunting?
Yes, the 150 grain soft point bullet is designed to expand on impact, which makes it a solid choice for whitetail deer and similar medium sized game. At 2,654 fps and 2,346 ft-lbs of energy, it has enough punch for ethical shots at typical hunting ranges.
Can I reload the brass from this ammunition?
Yes, this ammo uses Boxer primed, reloadable brass cases, which is the standard setup most American reloading equipment is built around. Just keep in mind that .303 British headspaces on the rim rather than the shoulder, so neck sizing only and keeping brass matched to the rifle it was fired in will help it last through more reloading cycles.
Is this .303 British ammo corrosive like old military surplus rounds?
No, this is new production ammunition with non-corrosive primers, so standard cleaning solvents and a normal cleaning routine are all you need after a range trip. That's a real advantage over old military surplus .303 ammo, which often used corrosive priming compounds that required immediate bore cleaning.
