What makes the S&B 357 Sig 140 Grain Tfmj Nontox suitable for indoor shooting ranges?

This ammunition features a patented NONTOX Boxer primer that is completely free of heavy metals such as lead, barium, mercury, and antimony. Combined with a Total Full Metal Jacket (TFMJ) projectile where the brass jacket fully encloses the lead core at the base, it significantly reduces airborne lead vaporisation and bore leading during high-volume indoor practice.

What firearm compatibility is required to shoot this 357 SIG ammunition safely?

This ammunition is strictly designed for firearms chambered specifically in 357 SIG, such as the Glock 31 or SIG Sauer P226. It must never be used in chambers sized for 357 Magnum, 38 Special, or 9x19mm due to critical differences in case dimensions and operating pressures.

What kind of performance and trajectory can I expect from this 140 grain load at distance?

Fired from a 5-inch test barrel, this round achieves a muzzle velocity of 412 m/s and 764 Joules of energy. When zeroed at 25 metres, it maintains a flat trajectory for standard handgun ranges but experiences accelerated drop beyond 50 metres, showing a -24.9 cm drop at 100 metres.

What are the legal requirements for purchasing and storing this ammunition in Australia?

In Australia, the purchase and possession of handgun ammunition require an appropriate state or territory firearms licence, typically Category H, along with proof of a registered firearm chambered in 357 SIG. Storage, transport, and handling must strictly comply with your local state legislation regarding explosives and dangerous goods.

.357 SIG Ammo - Sellier & Bellot V311172

The Sellier & Bellot .357 SIG NONTOX TFMJ 140 Grain ammunition (SKU: V311172) is engineered for high-volume handgun target shooting, law enforcement training, and action pistol competition. Designed specifically for firearms chambered in .357 SIG, this factory-loaded ammunition utilizes a 140-grain (9.00 g) Total Full Metal Jacket projectile paired with a patented heavy-metal-free NONTOX primer. Out of a standard 5-inch test barrel, the round produces a muzzle velocity of 412 m/s and 764 Joules of muzzle energy. The fully encapsulated lead core and heavy-metal-free ignition eliminate airborne lead, barium, mercury, and antimony emissions at the firing point, preventing bore leading and maintaining clean air quality in confined indoor shooting facilities.

Key Features

NONTOX Boxer Primer: Employs a patented ignition mixture free of lead, barium, mercury, and antimony to eliminate toxic airborne heavy-metal combustion residues.
Total Full Metal Jacket (TFMJ): Encloses the 9.00 mm diameter lead core entirely in CuZn 30 brass—including the bullet base—preventing lead vaporisation upon powder ignition.
Flat Ballistic Trajectory: Retains a velocity of 375 m/s and 634 Joules of energy at 25 metres, generating a minimal drop of -2.9 cm at 50 metres when zeroed at 25 metres.
Reloadable Brass Cases: Loaded in high-quality factory brass with a cartridge overall length of 28.96 mm.
Box Packaging: Supplied in standard 50-round packaging for training drills and match sessions.

Who is the S&B Sellier & Bellot 357 Sig 140 Grain Tfmj Nontox Ammo 50 Rd for?

Indoor range shooters — Requires toxic-fume-free air during extended handgun practice, which this 357 Sig handgun ammunition delivers via a fully encapsulated 140-grain TFMJ bullet base and a heavy-metal-free primer that eliminates airborne lead, barium, and mercury.
Law enforcement trainers — Conducting high-round-count duty handgun qualifications benefit from this 357 Sig handgun ammunition, which mirrors full-power defensive recoil impulse with 764 Joules of muzzle energy across 50 rounds per box.
Action pistol competitors — Demands flat handgun trajectories across typical 0–25 metre IPSC stages, supported by this 357 Sig handgun ammunition driving a 140-grain projectile at 412 m/s for zero drop at 25 metres and just -2.9 cm drop at 50 metres.

Less suitable for: Firearm platforms chambered in .357 Magnum, .38 Special, or 9x19mm (strictly chambered for dedicated .357 SIG firearms only). It is also not suitable for humane game hunting or personal defence; because this non-expanding TFMJ solid bullet will not deform or expand upon impact, dedicated expanding hollow-point ammunition or specialized game hunting cartridges are required for those applications.
