No. Even if it would fit in the chamber, there is no firing pin on a pellet gun.
It can't use a regular cartridge, no.
Air rifles use compressed air or C02 to propel the BB or pellet. They do not use gunpowder. Their is no bullet shell and bullet just the BB or pellet.
If you are referring to casings like bullet casings after the bullet has been discharged, then the answer is "No." The entire Pellet is discharged from the gun when it is fired.
No. A pellet gun would use compressed air.
I believe you are asking about an air gun that fires a 22 Cal pellet. The pellet is driven by air not gunpowder. Seewww.crosman.com to see several different Airgun models.
Use C02 to propell the pellet
Nope. Pellet guns are fairly safe to use.
I think you mean pellet gun. That is a gun that fires a small lead pellet but does not use gun powder. It uses compressed air or compressed gasses to push the pellet.
The breech area on any gun is the area where the pellet / bullet / BB is loaded into the barrel. The bullet stays here until the trigger is pulled.
No
No! And for those that think the bear will ignore it I'll just say this. If you are OUT OF YOUR MIND and use a pellet gun then the bear WILL NOT, I REPEAT, WILL NOT IGNORE IT! IT WILL ATTACK! Therfore the only out come is it will charge you while you are reloading your precious single-shot pellet gun and will have you for supper. If you are hunting deer or elk with a pellet gun then you can kill one because there are high-powerd pellet guns out there that are proven to kill medium game...BUT NOT LARGE GAME!
If you have a very powerful pellet gun and use very light pellets, getting a speed of over ~1150 feet per second is possible and will break the sound barrier. If you use WD-40 on the gun, it is recommended to wipe it off and then use gun oil. If you leave WD-40 inside the gun it could make the bullet faster, but it's more dangerous and wears down the parts inside.
