Caliber has nothing to do with it.
you cant board with it but you can leave it in your checked baggage. <><><> Correct- but if it is a gas gun, no propellant gas cartridges allowed, either in carry on or checked baggage.
Yes, you can carry an air gun in your checked baggage, but it must be declared to the airline and meet specific guidelines for transportation.
Other than in checked baggage, they are not allowed on airplanes anywhere. CO2 cartridges are not allowed on the plane- PERIOD.
Gun laws vary from one state to another. You would need to check to see if you are allowed to buy a 22 caliber at 20 years of age.
the 12 guage is a caliber not a gun
a .45 caliber.
I don't think so and I checked thoroughly. Where did you get the number? The model number and caliber should be stamped right into the barrel of the gun.
Take it to a gunsmith to have the chamber measured and the overall condition checked or plug the barrel and hang it on the wall for decoration.
What caliber of man are you looking for? What caliber of gun are you looking for?
No. You will be stopped, questioned, and may be arrested if you carry a gun in baggage.
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.
smaller the number, the smaller the caliber.
