S&B 357SIG 140GR FMJ 50/1000

Description

Sellier & Bellot’s 140-grain Full Metal Jacket load in .357 SIG is built for range work, training, and competition — anywhere you need to put rounds downrange consistently without burning through premium defensive ammunition. The FMJ construction uses a standard lead core enclosed in a CuZn 30 metallic jacket. That hard outer shell prevents deformation on feeding, which matters in a bottlenecked cartridge like the .357 SIG that already demands precise headspacing and reliable chamber entry. The non-expanding design also means no barrel leading, keeping your pistol cleaner over extended sessions.

The brass casing is Boxer-primed with a large pistol primer, which means spent cases can be collected and reloaded — a practical consideration for shooters who volume-train with a cartridge that typically costs more per round than 9mm. At the muzzle, the load generates 568 ft-lb of energy from a 5-inch test barrel, which is representative of the velocity you can expect from a full-size service pistol. Shorter barrels will shed some of that figure. Sellier & Bellot rates this as non-+P, so it runs within standard pressure parameters suitable for any .357 SIG-rated firearm. Available in boxes of 50 or cases of 1,000 rounds, the case quantity makes it practical for extended practice planning without constant reordering.
