357 Sig Bullets

This page contains just the projectile portion of a cartridge and is meant for reloaders. Please go to our 357 Sig Ammo Page for loaded ammo that's ready to fire.

Designed to deliver the power of a 357 Magnum out of a semi-automatic pistol, the 357 SIG’s flat trajectory and downrange energy advantage make it an excellent selection for self-defense. Yet the 357 SIG never found its footing in a country already enamoured with the 9mm and the 40 S&W, so finding ammo can be tricky.

Fortunately 357 SIG bullets for reloading are not uncommon at all. At .355 in diameter and 125 grains they are essentially identical to 9mm bullets, and as such are widely available.

As it is the 357 SIG’s parent case, it is theoretically possible to resize 10mm brass to reload 357 SIG bullets. The result is a case that falls slightly short of SAAMI spec, however. Purchasing new brass or repurposing spent 357 SIG cases is preferable.

Different sources will tell you that the 357 SIG headspaces on either the case mouth or the shoulder. You should let your handgun decide which type of headspacing it prefers. New reloaders should also take caution that the 357 SIG’s short neck may not properly seat some 9mm bullets, leading to setback. A .355 bullet with a wider bearing surface is optimal for the 357 SIG. The great abundance of .355 bullets on the market still give the handloader ample opportunity to reload this exciting cartridge!

    These are component bullets for handloading. This is not loaded ammunition that you can fire as soon as you open the box.

    Berry’s has remained family owned and operated since their foundation by Ray Berry in 1961. Today they’re well regarded among handloaders for the consistency of their component bullets – a reputation they’ve genuinely earned.

    This 0.355” diameter 115 grain plated hollow base round nose bullet is ideal for loading 9mm ammunition, but it is just as handy for 38 Super and 357 Sig. The bullet features a swaged lead core and electrochemically bonded copper jacket, which has been struck twice to guarantee its solid bond and uniform dimensions.

    Its electrochemically plated copper jacket completely envelops this bullet’s lead core. As the result it avoids producing vaporized lead during ignition to promote a healthier indoor shooting environment. The bullet’s core also remains undeformed, which alongside its balanced weight and standardized dimensions delivers exceptional accuracy.

    Berry’s recommends loading this 1.130” OAL bullet to a muzzle velocity no greater than 1,500 fps. They recommend a taper or roll crimp, but warn against over crimping that could cause core separation. Load data for comparable jacketed or cast 115 grain bullets may be used for these bullets as well.

    As you likely know, Hornady has been making top-quality ammunition for many years. They have some of the finest rifle and handgun rounds in the country, and also supply a large selection of reloading supplies and accessories like these 9x19 full metal jacket bullets.

    9mm is a fast and reliable caliber and although it has excellent stopping power, it also delivers manageable recoil, making it a favorite among target and competition shooters. If you go through lots of 9mm rounds, order this 3500-count box of 100 grain, enclosed full metal jacket bullets and you can reload your brass with high-quality projectiles.

    The full metal jacket in these rounds is extremely reliable in autoloading handguns. They are designed to feed smoothly from the magazine to the chamber, and will give you less fouling in the barrel. Down range, they are reliable and effective, resulting in superior performance during your competitions or training.

These rounds measure .355 inches in diameter and weigh in at 125 grains which is a versatile medium weight for both .357 SIG and 9mm Luger loads.

    Cheap, reliable, accurate

    I tried these bullets with two different powders, Blue Dot and Power Pistol. My loads turned out very comparable to 125g Winchester white box but were less than 1/3 of the price. The bullets worked well in my gun and shot accurately. I plan on purchasing them again.
