No
Any bullet that has a diameter of one half inch is a .50 caliber bullet. There are different .50 caliber bullets- my Hawken muzzle loading rifle shoots a .50 caliber lead bullet, but different from the .50 Browning Machine Gun (that is also used in the .50 Barret sniper rifle)
.50 caliber firearms have been made since the early days of muzzleloaders. The original maker of a gun in this caliber is not known. Given that .50 is 1/2 inch, a convenient measurement, .50 caliber muzzleloaders are very common. There are several .50 caliber cartridges in existence. They range from the .50BMG used in heavy machine guns and long range sniper rifles to the .50 Beowulf used in AR type rifles to .50 AE, .50 GI and .500 S&W used in handguns. These cartridges were invented by different people at different times.
The Desert Eagle was made in several caliber, including .50 Action Express, which is NOT the same cartridge as the .50 BMG used in the Barrett rifle.
A .50 caliber gun can be used as an anti aircraft weapon. I am not up to his caliber; he outperforms me on the job. An athlete of his caliber surely cannot be defeated.

The highest caliber bullet commonly used is a .50 cal. However, there are bullet that are larger in caliber. the 700 Nitro express comes to mind.
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.
Yes. .50 caliber refers to .5 of an inch.
Centurion medium tanks (84mm main guns, which they called 20 pounders). they also had two coax machineguns, one of which was a .50 caliber, originally intended as a spotter round for the Centurion's main gun. All US tanks only had one coax (7.62mm NATO).
No. .338 vs .500 If you are referring to World War 2, then you probably mean the .308 bullet used in the British Enfield rifle, the typical infantryman's rifle used in World War 1 & 2. It was a rifle round that was 0.308 inch diameter. The "50 Caliber" was a 0.500 inch caliber bullet that was about 4 inches in length that was used in heavy machine guns that were used on tanks and aircraft. Suggestion- You may also have been thinking about a .30-06 Springfield, which the M33 Ball .50 Cal ammuntion is based upon. The .50 Cal is actually on a super scaled up version of it. But no, a .338 is in NO way a .50 cal.
That was either the Spencer is .50 caliber or the Henry in .44 Rimfire.
