caliber
In guns, particularly firearms, caliber or calibre is the approximate internal diameter of the barrel, or the diameter of the projectile it fires, in hundredths or sometimes thousandths of an inch. For example, a 45 caliber firearm has a barrel diameter of .45 of an inch. Barrel diameters can also be expressed using metric dimensions, as in "9mm pistol." When the barrel diameter is given in inches, the abbreviation "cal" (for "caliber") can be used. For example, a small-bore rifle with a diameter of 0.22 inches can be referred to as .22 or a .22 cal; however, the decimal point is generally dropped when spoken, making it a "twenty-two caliber" or a "two-two caliber rifle".
In a rifled barrel, the distance is measured between opposing lands or grooves; groove measurements are common in cartridge designations originating in the United States, while land measurements are more common elsewhere. Good performance requires a bullet to closely match the groove diameter of a barrel to ensure a good seal.
While modern cartridges and cartridge firearms are generally referred to by the cartridge name, they are still lumped together based on bore diameter. For example, a firearm might be described as a "30 caliber rifle", which could be any of a wide range of cartridges using a roughly .30-in projectile; or a "22 rimfire", referring to any rimfire cartridge using a 22-cal projectile.
Firearm calibers outside the range of 17 to 50 (4.5 to 12.7 mm) exist, but are rarely encountered. Wildcat cartridges, for example, can be found in 10, 12, and 14 cal (2.5, 3.0, and 3.6 mm), typically used for short-range varmint hunting, where the high-velocity, lightweight bullets provide devastating terminal ballistics with little risk of ricochet. Larger calibers, such as .577, .585, .600, .700, and .729 (14.7, 14.9, 15.2, 17.8, & 18.5 mm) are generally found in proprietary cartridges chambered in express rifles or similar guns intended for use on dangerous game. The .950 JDJ is the only known cartridge beyond 79 caliber used in a rifle.
In some contexts, e.g. guns aboard a warship, "caliber" is used to describe the barrel length as multiples of the bore diameter. A "5-inch 50 calibre" gun has a bore diameter of 5 in (12.7 cm) and a barrel length of 50 times 5 in = 250 in (6.35 m).

This is a very nice example of a Beretta Tomcat in extremely clean condition. It's a .32 caliber with tilt up barrel. 7+1 capacity. Includes two magazines. Double-single action, thumb safety on the left side, half-cock option. Very safe to a carry loaded. Carbon steel barrel and slide on an...
This will vary on your favorite caliber. Recently, I had a sales clerk at Sportsmans Warehouse suggest that I seriously consider a .357 rifle and practice cheaply with. 38 specials. His suggestion sounded practical but I haven't read any reviews yet about accuracy to what distance. I have heard...
RUGER P-85 Automatic Pistol Caliber 9 x 19mm $400.
This pistol was purchased in Pennsylvania on March 3, 1989. It is still brand new in its original locking case. It has never been fired / used / or played with by anyone. It comes with its original paperwork and instruction manual along with...
Has anyone tried out the light bullet, high speed, self defense rounds available. I like the fact that light bullets creates less recoil and shoot flatter. In the micro compact type guns it seems like this would be a big plus not to mention the overall weight of the carry gun is lighter. Does...

Nice Remington 700 .243 owned by my father who bought it new in 1984. I have used it a few times, it is super accurate but I no longer hunt and need to sell a few more things. Very low round count, stock has a few dings/etc. Barrel/receiver/bore/all metal is in excellent...
