For most uses, a jacketed hollowpoint.
The .357 part of the name means that the bullet diameter .357 inches. I do not know what the "Magnum" means in the name.
The actual bullet diameter (as well as that of the .38 Special) is .357.
colt 357
The .357 Magnum is a larger cartridge, can fire a heavier bullet, and has about twice the energy of a 9mm Parabellum cartridge.
The distance a .357 Magnum bullet can travel depends on factors such as the specific load, barrel length, and angle of fire. On average, a .357 Magnum bullet can travel up to 1 to 1.5 miles if fired horizontally. However, it will lose velocity and energy over distance, decreasing its lethality.
357- as in .357 magnum, is the diameter of the bullets fired in fractions of an inch. It uses a bullet that is 0.357 inches wide.
.357 is the measurement of the bore of a gun. .357 Magnum is the name for a particular rimmed cartridge that uses .357 bullets. There are other cartridges using the same size bullet, but they are named differently because they are not interchangeable with .357 Magnum due to different case dimensions. People often call .357 Magnum just ".357" for short because it is the most common cartridge with this number in the name. It's the same as 9mm Luger being shortened to just "9mm" because it's the most common of the nines.
No. However, .38 Special ammo CAN be safely fired in a .357 Magnum firearm. Both cartridges use a bullet that is .357 in diameter- but the .357 magnum is longer, and more powerful.
No. It is a fatter diameter than .357, and will not fit. The bullet diameter is .361, instead of .357.
Yes and no. The. 40 S&W is not interchangeable with the .357 Magnum, if that's what you had in mind. Most .357 Sig pistols can, however, but a .40 barrel will have to be dropped in in place of the .357 Sig barrel.
Assuming we're talking about .357 magnum and .38 special revolvers, the most basic difference is a .357 magnum chamber is slightly longer than the .38. The .357 casing is also slightly longer than the .38 and holds more powder. The actual bullet (the piece of lead) is the same, but because of the higher pressure of the .357, the bullet travels faster and has more energy. .357 magnum guns are typically a little heavier than a similar gun in .38.
.357 Magnum refers to the cartridge in that caliber. SOME of those cartridges are loaded with a full metal jacketed bullet- meaning that the lead core of the bullet is completely surrounded by jacketing metal- usually an alloy of copper and other metals.
