You should never try to fire anything in any gun other than what it is designed to shoot. The .22 rounds will most likely not fit into the magazine or feed into the pistol. If they do, it can be dangerous if it actually fires. Additionally, .25 ACP is a centerfire cartridge where .22s are rimfire.
Very simply put, a rifle is designed to shoot accurately at a longer distance and bullets fired from a longer barrel will travel further with more acccuracy.
AFAIK, there has never been a 22 gauge shotgun. 20 and 24 yes, but no 22. A 20 gauge would put a small hole in a ceiling, depending on how construced and the type of ammunition use. Caliber refers to rifles and handguns. A 22 caliber will not do what you mention.
probably not... the bb size has to be the same caliber as the bb gun. the airsoft bb is also made of plastic so it would probably shatter inside of the barrel because it is too light.
A gun tucker is where you put the bullets
As many as you put in.
NO.
they all put bullets in there heads
I put one on my Savage 93.
In the magazine.
pictures and info in bullets
A cowboy gun is normally a revolver, which has six holes for the bullets to go in. But the cowboy would only put five bullets in for safety reasons. It was to stop the gun firing whilst it is in his pocket.
In the USofA it is legal. There are many handguns that are equipped from the factory with "features" to aid in mounting a scope.
