The Sellier & Bellot .357 Magnum 158 Grain Semi-Jacketed Hollow Point (SJHP) ammunition (Model: V312032) is designed for revolvers, lever-action rifles, and single-shot firearms chambered in .357 Magnum. Engineered for medium-game hunting, pest control, and target shooting, each cartridge pairs a 158-grain (10.25 g) projectile with a reloadable brass case and non-corrosive primer. Fired from a 150 mm test barrel, the load develops a muzzle velocity of 405 m/s (1,329 fps) and a muzzle energy of 841 Joules (620 ft-lbs). The exposed lead tip and CuZn 10 tombac jacket facilitate rapid, controlled expansion while retaining mass upon target impact.

Key Features:

• Controlled Expansion: The 158-grain SJHP bullet features an exposed lead core that initiates rapid mushrooming while maintaining high retained weight.
• Factory Reloadable Brass: Assembled in standard boxer-primed CuZn 10 brass cases with non-corrosive priming for extended shelf life and reloading capability.
• Downrange Energy: Generates 841 Joules at the muzzle, maintaining 749 Joules at 25 metres, 672 Joules at 50 metres, and 559 Joules at 100 metres.
• Consistent Trajectory: Offers a G1 ballistic coefficient of 0.184 and a sectional density of 0.177 lb/in², dropping 2.7 cm at 50 metres when zeroed at 25 metres.

Who is the S&B Sellier & Bellot 357 Mag 158 Grain Sjhp Ammo 50 Rd for?

• Medium-game hunters — provides 841 Joules of muzzle energy and a 158-grain expanding bullet that retains 672 Joules at 50 metres for clean terminal penetration in .357 Magnum revolvers and rifles.
• Pest control shooters — delivers a flat short-range trajectory dropping just 2.7 cm at 50 metres from a 25-metre zero, with 405 m/s velocity for rapid energy transfer on feral pests.
• Lever-action silhouette competition shooters — supplies uniform factory-loaded handgun hunting ammunition packed in 50-round boxes, maintaining 559 Joules of knockdown energy at 100-metre rams.

Less suitable for: Long-range shooting beyond the 100 m envelope where energy drops to 559 Joules and trajectory drop reaches -22.6 cm; choose a dedicated flat-shooting centrefire rifle calibre instead. Never chamber in .38 Special firearms due to higher .357 Magnum operating pressures.
