Sellier & Bellot .357 Magnum 158 Grain Soft Point (SP) Ammo
Dependable European .357 Magnum ammunition engineered for hunting, target competition, and range practice.

Product Overview
Sellier & Bellot .357 Magnum 158 grain Soft Point ammo (Part #SB357B) delivers time-tested accuracy and high energy output for revolver shooters, lever-action carbine users, and handgun hunters. Produced in Vlasim, Czech Republic, Sellier & Bellot has manufactured premium ammunition since 1825, combining centuries of craftsmanship with modern manufacturing precision.
Featuring a 158-grain Semi-Jacketed Soft Point (SP) projectile, this load provides a copper jacket surrounding a lead core with an exposed lead tip. Traveling at 1,263 fps out of a standard test barrel, it generates 560 ft-lbs of muzzle energy. The soft point design facilitates reliable mushrooming and weight retention upon target impact, making it effective for medium game hunting such as deer and wild boar. Loaded in reloadable brass casings with non-corrosive Boxer primers, it ensures reliable ignition and smooth cylinder rotation.

Compatibility & Usage Notes
This ammunition is intended for firearms chambered in .357 Magnum that are in good working condition. It is safe for use in revolvers and lever-action rifles chambered in .357 Magnum. Do not attempt to load or fire .357 Magnum cartridges in firearms chambered solely for .38 Special, as excessive chamber pressures will lead to severe firearm damage or personal injury. Store ammunition in a cool, dry place away from children and unauthorized users.
Frequently Asked Questions
Can I fire Sellier & Bellot .357 Magnum in a .38 Special revolver?
No. The .357 Magnum casing is longer and loaded to much higher pressures than .38 Special. Firing .357 Magnum in a .38 Special revolver is unsafe and the cartridge will not fully chamber.
Is Sellier & Bellot .357 Mag brass reloadable?
Yes. Sellier & Bellot uses high-quality reloadable factory brass cases and non-corrosive Boxer primers.
Is Soft Point (SP) ammo safe for lever-action rifle tube magazines?
Yes. Soft point bullets feature blunt, lead tips that will not detonate primers in a tubular magazine, making them a popular option for .357 Mag carbines.
