20 mm caliber is a specific size of popular autocannon ammunition. The dividing line between smaller-caliber weapons, commonly called " guns ", from larger-caliber " cannons " (e.g. machine gun vs. autocannon ), is conventionally taken to be the 20 mm round, the smallest caliber of autocannon.
The Anzio 20/50 has approximately 22,000 ft⋅lbf (30,000 J) of kinetic energy with an 800-grain (52 g) bullet. It does this by taking the .50 BMG projectile, which already is relatively large and travels extremely fast, and increases the already supersonic bullet to over 1.3 times its normal flight velocity, creating more kinetic energy ...
Common rifle cartridges, from the largest .50 BMG to the smallest .22 Long Rifle with a $1 United States dollar bill in the background as a reference point. This is a table of selected pistol/submachine gun and rifle/machine gun cartridges by common name. Data values are the highest found for the cartridge, and might not occur in the same load ...
American fighters with .50 caliber (12.7 mm) main armament, such as the P-51 and P-47, had to be close to enemy aircraft in order to hit and damage them. The 20 mm (0.79 in) Hispano cannon carried by the P-38 and P-61 , while formidable against propeller-driven planes, had a relatively low rate of fire in the age of jets, while other cannons ...

.950 JDJ cases are approximately 70 mm in length, and are based on a 20×102mm Vulcan case shortened and necked up to accept the .950 in (24.1 mm) bullet. Projectiles are custom-made and most commonly weigh 3,600 grains (230 g) which is 8.2 ounces or over half a pound.
In a side-by-side comparison with the .50 BMG (43 g), the 15 gr (1 g) titanium round of any caliber released almost 2.8 times the energy of the .50 BMG (1 g at 10 000 m/s = 50 000 joules), with only a 27% mean loss in momentum. Energy, in most cases, is what is lethal to the target, not momentum. [8]
The .500 Linebaugh utilizes a bore diameter of .500" with the corresponding bullet diameter of .510", the same as the .50 BMG and other .50 caliber rifles, while the .50 Action Express, .500 S&W Magnum, and .500 S&W Special use .490" bore diameters and correspondingly smaller .500" bullet diameters. The smaller .500" diameter was further ...
