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.)
The bore is the inside of the barrel- that is, the hole that the bullet is fired through. The diameter of the bore is measuring how wide the bore is from one side to another.
