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.
No, there are .357 caliber bullets that are not magnum, but they are in the minority.
If the weapon is chambered in 357 Magnum, you can fire the round in it.
"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.
The .45 caliber is bigger in diameter. If you mean weight. The .45 caliber is generally heavier. However there are some lightweight .45 caliber bullets that are lighter than .357 caliber bullets. Generally speaking .45 caliber bullets weigh between 180 - 230 grains. While .357 caliber bullets generally weigh between 158 - 180 grains. If you are talking about diameter, the .357 caliber bullets are approximately 0.357 inches in diameter. The .45 caliber is approximately 0.450 inches in diameter. Again, using this measure, the .45 caliber is the larger bullet.
The actual bullet diameter (as well as that of the .38 Special) is .357.
