Full Metal Jacket 158gr Bullet – Classic .357 Magnum Profile
The 158-grain FMJ bullet is a time-tested standard in .357 Magnum:
Traditional bullet weight for .357 Magnum, offering a familiar recoil impulse and consistent point-of-impact relative to many defensive loads of the same weight.
Full Metal Jacket construction reduces barrel leading and promotes smooth feeding in both revolvers and lever-action carbines.
Ideal for range work, target shooting, training, plinking, and drills where expansion is not required.
If you want a training round that closely mimics the feel of classic .357 Magnum defensive loads—but at a more economical price point—this 158gr FMJ is a solid choice.
Clean-Burning, Reloadable Brass Cases
Sellier & Bellot is known worldwide for producing high-quality brass-cased ammunition:
Reloadable brass allows handloaders to save and reuse cases, extending the value of each case of ammo.
Boxer primers make decapping and re-priming straightforward for reloaders.
Modern, non-corrosive primers and clean-burning powders help minimize fouling and reduce cleaning time between sessions.
For shooters who run a lot of .357 Magnum, that combination of quality brass and consistent primers makes S&B SB357A an appealing bulk option.
Reliable Performance in Revolvers & Carbines
The Sellier & Bellot .357 MAG 158GR FMJ is designed to perform in a wide range of platforms:
Double-action and single-action revolvers from popular manufacturers such as Smith & Wesson, Ruger, Taurus, and others.
Lever-action and semi-automatic carbines chambered in .357 Magnum / .38 Special that are rated for full-power .357 loads.
Suitable for both indoor and outdoor ranges, provided .357 Magnum is permitted by the facility.
Always ensure your firearm is chambered for .357 Magnum (not just .38 Special) before firing this ammunition, as it is a higher-pressure cartridge.
Perfect for Training, Range Use & Skill Building
This 158gr FMJ .357 Magnum is ideal for:
Regular range practice with your carry or duty revolver.
Recoil management training to help shooters get comfortable with full-power .357 loads.
Marksmanship practice and steel shooting where a consistent, non-expanding projectile is preferred.
Introductory training on lever guns in .357 Magnum, especially when transitioning from lighter .38 Special loads.
Using the same bullet weight as many defensive loads helps ensure your practice ammo feels and shoots similarly to your carry ammunition.
Bulk Case – 1,000 Rounds for High-Volume Shooters
With 50 rounds per box and 20 boxes per case, the SB357A configuration gives you:
1,000 rounds total, making it easy to plan multi-session training blocks or supply a full class or club event.
Economical bulk pricing (typically lower cost per round than buying single boxes).
One convenient case to store, transport, and inventory your .357 Magnum training ammo.
If you’re serious about maintaining proficiency with your .357 Magnum, buying by the case is a smart way to ensure you always have ammo available for your next range day.
