The Sellier & Bellot .357 Magnum NONTOX TFMJ 158 Grain ammunition (Manufacturer Part Number: V311132) is engineered for high-volume indoor shooting, club competitions, and tactical training. Designed to eliminate toxic airborne emissions, this cartridge features a heavy-metal-free NONTOX primer alongside a Total Full Metal Jacket (TFMJ) projectile. The completely enclosed lead base prevents lead vapourisation during ignition, reducing airborne contaminants in poorly ventilated or enclosed range environments. Tested in a 6-inch barrel, this standard-pressure .357 Magnum load delivers a muzzle velocity of 1,263 fps (385 m/s) and a muzzle energy of 560 ft-lb (760 J), maintaining reliable cycling and clean combustion across revolvers and lever-action firearms.
Key Features
- NONTOX Primer Technology: Uses a patented primer formulation free from lead, barium, mercury, and antimony, preventing toxic heavy-metal by-products from venting into the range atmosphere.
- Total Full Metal Jacket (TFMJ): Encloses the 158-grain lead core entirely within a CuZn 10 tombac jacket, sealing the base to prevent hot propellant gases from vaporising lead.
- Clean-Burning Performance: Formulated to minimise chamber fouling and barrel rifling deposits, extending cleaning intervals during high-volume shooting sessions.
- Predictable Trajectory: Offers an estimated power factor of 199.6 kgr·fps and a G1 ballistic coefficient of 0.184, retaining 1,147 fps and 462 ft-lb of energy at 50 yards with a mild drop of -0.9 inches.

Who is the S&B Sellier & Bellot 357 Mag 158 Grain Tfmj Nontox Ammo 50 Rd for?
- Indoor shooting range members — Needs enclosed-facility compliance, utilising heavy-metal-free primers and fully enclosed bases to eliminate airborne lead, barium, and antimony while delivering 1,263 fps muzzle velocity from this .357 Magnum handgun ammunition.
- Handgun club competitors — Requires a consistent competition load, providing a 199.6 kgr·fps power factor and 50-round packaging with a 158-grain projectile that drops just -0.9 inches at 50 yards.
- Tactical training participants — Operates through high round counts in confined training bays, relying on a 50-round box of clean-burning .357 Magnum cartridges designed to reduce lead exposure and barrel fouling during rapid strings of fire.
Less suitable for: Medium game harvesting, as the non-expanding 158-grain TFMJ bullet produces straight-line penetration that is legally prohibited or ineffective for hunting; expanding semi-jacketed soft point (SJSP) or hollow-point .357 Magnum hunting ammunition is required instead. It is also not rated for use in firearms specifying +P ammunition loads.
