Do you mean a firearm or a paintball gun?
paintballs
No, paintballs can vary in size depending on the type of gun being used. It is important to use the correct size paintballs for your specific gun to ensure proper performance.
You can buy airsoft paintballs, but they're the size of a small pellet and I've had a hard time finding them. Technically no. There are NO paintballs that work in an airsoft gun. The answer above was partially correct though. They make marker bbs that are basically bbs but they have paint on them.
You must be 18 to buy any Paintballs, markers, tanks, masks or most other paintball accessories or gear.
For optimal performance with a paintball gun, it is recommended to use high-quality, tournament-grade paintballs. These paintballs are more consistent in size and shape, which helps improve accuracy and reliability when firing.
You can buy rubber paintballs, they are called Reballs, and any paintball gun can shoot them. The police and militairy also have several specialized or modified guns to shoot them at higher FPS.
Freezing paintballs make them brittle. And will likely break wen fired, spraying paint all down the barrel of the gun :(
No. They will be too large to fit in the gun or be fired out of the barrel.
without CO2 or paintballs, you just put the bolt forward. In most guns this is how you de-cock after a day of play, but if you have a regulator, it may store a single shot. If you fire without co2, the gun will not cycle or fire a paintball, it will only go into the barrel. If you fire with no paintballs and co2, you may damage your gun.
Hopper or Loader
they are balloons...
There are no 45 caliber paintballs. If there were, you still could not use them in a 50 caliber, due to the barrel being larger and that you would have 1 and 1/4 paintballs in the chamber at a time, which would chop every time.
