The Sellier & Bellot .357 Magnum NONTOX TFMJ 158gr ammunition is engineered for clean, low-emission target practice and handgun training in indoor and enclosed firing ranges. Featuring a Total Full Metal Jacket (TFMJ) with an enclosed base and a patented heavy-metal-free priming compound, this factory-loaded cartridge eliminates airborne emissions of lead, barium, mercury, and antimony upon ignition. Designed for CIP-standard .357 Magnum revolvers and lever-action rifles, each cartridge delivers a muzzle velocity of 1,263 fps (385 m/s) and a muzzle energy of 560 ft·lb (760 Joules) from a standard 150 mm test barrel.

Key Features

• NONTOX Primer Technology: Employs a heavy-metal-free priming compound that produces zero toxic lead, barium, mercury, or antimony emissions during firing.
• Total Full Metal Jacket (TFMJ): Features a CuZn 10 brass jacket that completely encloses the 158-grain lead core, preventing hot propellant gases from vaporising lead at the bullet base.
• Range-Optimised Ballistics: Produces an estimated power factor of 199.6 kgr·fps with a G1 ballistic coefficient of 0.184 and a factory 25-metre zero trajectory.
• Clean Burning: Minimises airborne combustion residue and interior firearm fouling during high-volume strings of fire.
• Standard Dimensions: Manufactured to an overall cartridge length of 1.590 in (40.39 mm) with an individual cartridge weight of 15.7 g.

Who is the Sellier & Bellot .357 Mag 158gr Non-Tox Tfmj 50 Pack for?

• Indoor range target shooters — Shooters operating in enclosed facilities benefit from this handgun training ammunition because its enclosed-base bullet and NONTOX primer eliminate airborne lead and heavy-metal vapour while maintaining a factory muzzle velocity of 1,263 fps.
• High-volume match and competition trainers — Competitors running revolvers or lever-action rifles benefit from this .357 Magnum cartridge generating 560 ft·lb of muzzle energy and an estimated 199.6 kgr·fps power factor with consistent 158-grain target trajectories.

Less suitable for: Shooting targets beyond 100 metres where velocity drops to 319 m/s and bullet drop exceeds 25.1 cm (where flatter-shooting centerfire rifle cartridges are better suited), or for hunting medium and large game where expanding soft-point or jacketed hollow-point projectiles are required.
