Elephant gun.
the 12 guage is a caliber not a gun
a .45 caliber.
What caliber of man are you looking for? What caliber of gun are you looking for?
With a pink elephant gun.
The short answer is no. The longer answer is, you might be able to get a .40 caliber cartridge to fire from a .45 caliber gun, but it may damage the gun, and even if it doesn't damage the gun, it will cause other problems. In general (with only a few exceptions) you should never try to fire any cartridge in any gun other than a gun designed for that caliber.
Caliber "Caliber" is a word for the diameter of the bullet or the bore of the gun.
It is the standard .68 caliber
Caliber has nothing to do with it.
smaller the number, the smaller the caliber.
Fifty caliber, but it is more of a toy than a paintball gun.
45 caliber Machine Gun and 50 caliber machine gun
