That depends on make and model. A typical "snub nosed" compact .357 Magnum revolver would hold five rounds, whereas a full sized revolver will usually hold six. The Desert Eagle .357 Magnum has a standard magazine capacity of nine rounds.
No, but a 38 special will work in a 357
No, there are .357 caliber bullets that are not magnum, but they are in the minority.
Just the bullets, or the complete cartridge? You'd be looking at anywhere from $25 - $75 for a box of 50, depending on the load and manufacturer.
If the weapon is chambered in 357 Magnum, you can fire the round in it.
Your gun is a 357 and can shoot both 357 ammo and 38 special ammo. The nice thing about these guns is you can practice at the range with 38S bullets, which are much cheaper, and save the 357 ammo for home defense.
Yes, but please use the correct term- cartridges. Not bullets. A .38 Special is basically a .357 Short, and you can safely shoot .38 Special in a .357 magnum. The opposite is NOT true.
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.
38 or 357
"caliber" as used in the firearms world can either mean just the bullet diameter, or the inside measure of bore diameter, expressed as a decimal fraction of an inch. And "caliber" can also mean the complete name of a specific cartridge, which might be quite different from some other one using the same caliber bullets. Examples: The caliber ".357 magnum" uses .357" (or 357/1000 inch) bullets. The caliber ".308 Winchester" uses .308" bullets. But the caliber ".30-06 Springfield" ALSO uses those same .308 bullets. But it's a different "caliber" because it's not the same cartridge. The .30-06 has a much longer case that holds more gunpowder.
Yes
No. <><><> Above is correct- however, ,38 Special CARTRIDGES can be used in a .357 magnum revolver. The .38 Special is actually not .38 caliber, but .357 caliber. .38 caliber bullets, such as used in the .38 S&W catridge, cannot be used.
The ammunition is called .357 Sig. Most pistols in .357 Sig can shoot the .40 S&W when you drop in a .40 S&W barrel.
