Description
Sellier & Bellot has been making ammunition since 1825, and their 357 Magnum 158-grain FMJ is a straightforward practice round that does its job without drama. The full metal jacket design means the bullet stays intact on impact, which keeps barrel fouling minimal and makes cleanup easier between range sessions.
What you get is a load specifically built for target practice and competition shooting. The 158-grain bullet hits around 1,263 feet per second with approximately 560 foot-pounds of muzzle energy. That's moderate power for the 357 Magnum cartridge, making recoil manageable enough that you can shoot extended sessions without fatigue. The flat-tip design works in both revolvers and lever-action rifles with tube magazines, giving you flexibility with what you can run it through.
Reliability From European Manufacturing
Each round uses a brass case with a non-corrosive Boxer primer and a lead core wrapped in a copper jacket. The brass cases are reloadable if you want to get into handloading down the line. These rounds consistently feed and extract without drama, which is what you want when you're trying to focus on marksmanship rather than troubleshooting ammunition.
Made For Extended Range Sessions
The full metal jacket construction keeps barrel leading down to a minimum, so you can shoot more rounds before you need to scrub the bore. The clean-burning powder also means less carbon buildup inside your gun. If you're putting together training sessions or working on accuracy at the range, this is the kind of round that lets you focus on your shooting instead of worrying about whether your ammo will work.

Frequently Asked Questions
Is this Sellier & Bellot 357 Magnum ammo safe to use in my revolver?
Yes, this ammunition is loaded to CIP specifications and works safely in any standard .357 Magnum firearm. The rounds cycle reliably in both revolvers and lever-action carbines. Make sure your specific gun is in good condition, and always follow basic safety practices.
Will this ammo work in my lever-action rifle?
Absolutely. The flat-tip FMJ design is safe for tube magazines found on lever-action rifles. These rounds work well in both revolvers and carbines, giving you a versatile practice load if you shoot multiple platform types.
Can I reload these brass cases?
Yes. The Boxer-primed brass cases are reloadable, which appeals to handloaders looking to stretch their dollar further. The cases are built to withstand multiple reload cycles if you decide to get into that side of the hobby.
Is this ammo magnetic or will it pass range screening?
These rounds feature non-magnetic bullets, so they will pass magnet tests at ranges that screen ammunition. The copper jacket and lead core combination is common among target rounds and should be accepted at most public ranges.
