158-Grain FMJ – Classic .357 Magnum Training Load
The 158-grain bullet is a time-proven standard in the .357 Magnum world and remains one of the most popular weights for both defensive and target loads.
Consistent recoil impulse: Training with 158gr FMJs helps replicate the feel of many defensive loads of the same weight.
Full Metal Jacket design: Minimizes barrel leading and promotes smooth feeding in both revolvers and .357 Magnum carbines.
Ideal for range practice, general plinking, competition warm-ups, and tactical drills where expansion is not required.
If you want your practice ammo to closely match the handling of your carry or field loads, 158gr FMJ is the logical choice.
Clean-Burning Powder & Reliable Ignition
Sellier & Bellot has built a reputation for clean, consistent ammunition that runs well in a wide variety of firearms.
Non-corrosive Boxer primers provide dependable ignition shot after shot.
Clean-burning powder helps reduce excessive fouling, making cleanup easier after long range sessions.
Consistent powder charges contribute to repeatable velocities and predictable point of impact.
The result is a .357 Magnum load that keeps your gun running smoothly and your groups tight.
Brass, Reloadable Cases – Extra Value for Handloaders
Each SB357B round uses quality brass cases that are fully reloadable:
Brass construction handles the pressures of .357 Magnum while offering long case life when properly sized and maintained.
Boxer-primed cases make decapping and re-priming straightforward for U.S. reloaders.
Buying by the case gives handloaders a large batch of matching headstamp brass, perfect for consistent reloading recipes and chrono work.
If you roll your own ammo, this is an efficient way to build up a supply of high-quality .357 Magnum brass.
Versatile Performance in Revolvers & Carbines
Sellier & Bellot .357 Mag 158gr FMJ is designed to function reliably in a wide range of firearms chambered for .357 Magnum:
Double-action and single-action revolvers from popular brands like Smith & Wesson, Ruger, Taurus, and more (as long as they are .357 Magnum rated).
Lever-action carbines and some semi-auto platforms chambered in .357 Magnum that are suitable for full-pressure loads.
Works well in both indoor and outdoor ranges, subject to local rules regarding magnum calibers.
Always confirm your firearm is marked for .357 Magnum before using this ammo. Do not use .357 Magnum in guns marked for .38 Special only.

Bulk Case – 1,000 Rounds for Serious Shooters
With 20 boxes of 50 rounds each, SB357B’s case configuration is built for high-volume shooters:
1,000 total rounds let you plan multi-day classes or regular range trips without constantly reordering ammo.
