If you mean a 50 caliber gun, it takes a 50 caliber bullet, but there are a couple of different kinds. Are you referring to a rifle or a handgun? If you are talking about a handgun like a desert eagle then it is a 12.7x33 in metric, .50AE standard. If you are talking about a rifle then it can be 12.7x99 in metric, .50BMG standard used in rifles like the M-82 or it can be a 12.7x108 metric used in rifles like the Gepard M-1. Also the bore in all the .50's is really .511.
Depending on the bullet, 9mm goes slower than it, but a 45-50cal.

Drop a bullet from the height you will be holding your weapon when you fire it. The time it take for the dropped bullet to hit the ground is how long it will be in the air after it is fired. (i.e. 1.5 seconds). Now take this time multiplied by the bullet speed of your particular gun (say 3000ft/second) and there you have it...1.5seconds X 3000 ft/second = 4500ft.
The .22 caliber bullet is ABOUT .22 inches wide. A .32 bullet is about .32 inches wide. The bullet will also be heavier due to size.
