Caliber typically refers to the maximum diameter of a gun's barrel in hundredths of an inch.
Sometimes a stated caliber (like .38 Special) is not equal to its actual caliber (.357 caliber). This is due to several reasons:
1- Marketing,
2- Measuring barrel diameter land to land,
3- Measuring barrel diameter groove to groove.
4- Measuring diameter of the chamber (brass casing diameter).
Usually when a firearm uses millimeter instead of caliber, it tends to be a more accurate description of the projectile's diameter.
Either platform can be larger than the other. The 45 has the larger projectile. Caliber is defined as the diameter in fractions of an inch, so .40 caliber is smaller in diameter than .45 caliber. Caliber can also be defined in the metric system, measured in milimeters. The .40 caliber cartridge is equivalent to 10mm in diameter. As noted, the size of a handgun can vary widely within one caliber, so it is perfectly reasonable to have a smaller handgun crafted in a larger caliber.
No such thing. You can have small caliber but not low caliber.
the are also chambered for the 38 caliber, 9mm caliber and 22 caliber
What caliber of man are you looking for? What caliber of gun are you looking for?
.32 caliber
30 caliber
.45 caliber
A 5.56mm is the same thing as a .225 caliber. If you do the math, a 30 caliber is MUCH bigger!
The caliber is defined as the diameter of the projectile that a certain firearm fires.A good example is the 308 Winchester.This is a rifle that fires a .308in.diameter bullet thru the barrel of this firearm.Most firearms fire a projectile that is under a 1/2in.in diameter projectile.They range in size from .223 to .452"in.I hope that you find this informative.
a .22 caliber
.32 caliber
Close. a .38 caliber is usually closer to .357 caliber.
