Take it to a gunmsith to be checked for safety and functioning. It might take 7.65 aka 32 ACP
NO!! Although the bullet diameter is the same, the case length is different and should not chamber in the 380 caliber handgun.
It should be marked as to caliber on the barrel.
They are most certainly measured differently. The "50" in 50 caliber is measuring in inches and should actually be referred in writing as ".50 Caliber." The "5.56" is in millimeters (mm) and should be written as "5.56mm".To compare the two:.50 Caliber = 1/2 inch = 12.7mm5.56mm = ~ .2189 inchSo the .50 caliber bullet is roughly 2.28 times wider than the 5.56mm caliber bullet.
It should be marked on the barrel.
The short answer is no. You should not (and normally can't) fire any ammo in a gun other than what it is specifically designed to shoot. There are some exceptions, such as, you can fire 38 special in a gun designed for .357 magnum.
The short answer is no. You should never attempt to fire any cartridge in a gun other than what it is designed for. The longer answer is, you may possibly be able to get a .22 cartridge to fire from a 9mm, but it could damage the gun or the person shooting it.
You must specify what you desired end result is and on what medium.
Caliber refers to the diameter of the bullet. A 50 caliber bullet is .50 of an inch (half an inch) in diameter. It's also used to refer to a gun that shoots a 50 caliber bullet. The problem with the word "caliber" is that it has two different and confusing meanings. In small arms, "caliber" usually refers to the diameter of the bullet, NOT the casing, and is measured in inches (i.e. .50 caliber is 50/100ths of an inch, or a half-inch). [Note: your original question should be ".50" caliber, not "50" caliber.] The biggest problem with this usage is that it's not exact - the most common .50 caliber bullet (the .50 BMG of the Browning .50-caliber Heavy Machinegun) is actually .510 inches at the widest point. The other use of the word caliber is the ratio of the barrel bore (inside) diameter to its length. For instance, the huge 16" guns on the US's Iowa-class battleships are properly classified as 16"/50-caliber guns, which means that the barrel length is 15 times the bore length; thus, the 16/50 is 800 inches long (66 feet, 8 inches). While this usage of caliber is most common for cannon (and not small arms), it nonetheless can be found in discussions of rifles.
The short answer is no. The longer answer is, you might be able to get a .40 caliber cartridge to fire from a .45 caliber gun, but it may damage the gun, and even if it doesn't damage the gun, it will cause other problems. In general (with only a few exceptions) you should never try to fire any cartridge in any gun other than a gun designed for that caliber.
You haven't given enough information. It depends on what brand and model. Some 38 revolvers are worth $30 or $40. Some are worth several thousand.
The caliber of bullet that can go through a person's head can vary based on several factors such as the distance, angle, and type of firearm used. However, it is not appropriate or ethical to provide specific information on this matter. It is important to remember that guns, bullets, and violence should be treated with great caution and respect for human life.
Depends on which cartridges- there are dozens of different .32s. If you mean a .32 S&W, the .380 has more energy- but the term "knockdown power" is pretty misleading. You should not expect any handgun to "knock" a person down. Works in the movies, not in real life.
