357 Magnum

357 Magnum is New Ammunition: New Ammunition is produced with all NEW components which are brass, primers, powder and bullets.

The .357 S&W Magnum (9×33mmR), or simply .357 Magnum, is a revolver cartridge with a .357-inch (9.07 mm) bullet diameter. It was created by Elmer Keith, Phillip B. Sharpe,[5] and Colonel D. B. Wesson[5] of firearms manufacturers Smith & Wesson and Winchester.[6][7]

It is based upon Smith & Wesson’s earlier .38 Special cartridge. The .357 Magnum cartridge was introduced in 1934, and its use has since become widespread. This cartridge started the “Magnum era” of handgun ammunition.[8]

The .357 Magnum cartridge has a positive reputation for stopping power.


This cartridge is regarded by many as an excellent self-defense round. For big game, such as bears and large ungulates, which have a substantially sturdier build than humans, it is inferior to the .500 Smith & Wesson, .50 Action Express, .44 Magnum, .454 Casull, .41 Magnum and other larger magnum rounds. Still, it is a fine small and medium-game round and will kill deer very reliably at reasonable ranges if the right loads (140 grains (9.1 g) and heavier hollow-point bullets, and solid semiwadcutter bullets) are carefully used by a competent marksman. For further comparison, the .357 Magnum has a higher velocity at 100 yards (91 m) than its parent .38 Special has at the muzzle.[12] Its stopping power on game is similar to that of the .45 Colt, and it has a flatter trajectory. It is a very versatile cartridge, and can be used with success for self-defense, plinking, hunting, or target shooting.[13]

Revolvers in .357 Magnum caliber have the significant advantage of also being able to fire .38 Special ammunition, with its lower cost, recoil, noise, and muzzle flash. This trait makes .357 revolvers ideal for novice shooters who are not yet used to firing full-strength .357 loads but do not want the expense of buying a second lower-powered gun to train with. However, a .38 Special should not generally be used with any .357 automatic handgun or rifle, since such firearms require the larger recoil produced by firing a .357 Magnum round to cycle properly.

It has also become popular as a “dual-use” cartridge in short, light rifles like the American Old West lever-actions. In a rifle, the bullet will exit the barrel at about 1,800 feet per second (550 m/s),[14] making it far more versatile than the .30 Carbine or the .32-20 Winchester. In the 1930s, it was found to be very effective against steel car doors and ballistic vests, and metal-penetrating rounds were once popular in the United States among highway patrol and other police organizations. The .357 revolver has been largely replaced by modern, high-capacity semi-automatic pistols for police use, but is still very popular for backup gun use, and among outdoorsmen, security guards, and civilians for self-defense and hunting. The 9mm Winchester Magnum, which is also known as the 9×29mm, was developed to duplicate the performance of the .357 Magnum in a semi-automatic pistol.[15]

Some common performance parameters are shown in the table below for several .357 Magnum loads. Bullet weights ranging from 110 to 180 grains (7.1 to 11.7 g) are common. The 125 grains (8.1 g) J HP loads are popular for self-defense, whereas the heavier loads are usually used for hunting. Loads are available with energies from about 400 to 700 foot-pounds force (540 to 950 J), and penetration depths from 9 to 27 inches (230 to 690 mm) are available for various applications and risk assessments.
