What is rifle bore?
The bore is the inside of the barrel of the gun. Bore dimension for most rifles is caliber, which is the bore diameter in fractions of an inch or in millimeters.

Gauge is the number of round balls fitting the bore that can be made from a pound of lead.
What is a calliber?
Two different meanings for firearms. For artillery, caliber is the relation of the diameter of the bore to the length of the barrel. A gun on a Navy Destroyer might be known as a 5 inch 38 caliber- meaning it fires a 5 inch diameter shell, and the barrel is 38 times 5 inches long. However, for rifles and handguns, it means the fractions of one inch that equal the diameter of the bore. So a .30 caliber rifle has a bore than measures ABOUT .30 inches, a .50 caliber ABOUT .50 inches, and so on. Some firearms have measurements from the metric system- a 9millimeter pistol has a bore diameter of ABOUT 9mm.
Is the rifle .22 in inches?
Yes. Among the smallest modern cartridge firearms is the "22 caliber" size, which is actually .22 caliber or 0.22 inches, about 5.6 mm of internal bore diameter. There are both numerous handguns and rifles that use this dimension, which has the benefits of relatively inexpensive ammunition and an extremely small recoil.
How is a 20 inch gun measured?
In the US, rifled guns (handguns, rifles, machine guns, and cannons (artillery) caliber is measured from "lands to lands" (inside the bore); in Europe caliber is measured from the grooves. The lands are the raised portion of the inside steel barrel (inside the bore), the grooves are the cut portion, the valleys of the bore's interior. Therefore, a 20" gun would measure close to 20 inches directly across from one "land" to the other "land." If you measure from groove to groove, the diameter will be larger.

What side is the bore on a gun?
The bore refers to the hole in the gun barrel thru which the projectile (bullet) passes. Some guns have a smooth bore, but many modern guns, both pistols and especially rifles, have a rifled bore, that is, the bore has a helical (spiral) groove that causes the projectile to spin as it flies thru the air. The diameter of the gun's bore determines the size of the bullet or shell (e.g. .22, .45, 9mm, etc.)
