At the time of writing (February, 2025), there simply aren’t many varieties of factory-loaded 400 Legend ammunition available. If you want out-of-the-box subsonic performance, your options are pretty much limited to the ammo you’re now looking at. It’s Winchester Super Suppressed!

This cartridge’s propellant charge isn’t weak. Its bullet is just very heavy, and therefore incapable of breaking the 1,125 fps sound barrier (Winchester recorded the round’s 1,060 fps and .318 G1 ballistic coefficient with the aid of a 20” test barrel). It’s ideal performance if you’re trying to make the most effective use of a suppressor, though you can look forward to quiet performance even if your muzzle lacks any devices.

The open tip is designed for target shooting. Its nose cavity and jacket aren’t designed for terminal expansion (though we’re sure you could successfully implement this ammo during a battle against varmints). The open tip’s jacketed base conserves accuracy by minimizing lead fouling, and it has a welcome effect on suppressor baffles as well. Made in America!
