Rifle or handgun?
Any caliber can do the job. Most states regulate what can be used.
Generally the .177 caliber universal pellet or BB is the most common ammunition for an air rifle. However other pellets are available for larger bore air rifles. These include. .20, .22, .25, .30, 9MM, 45 cal, 357 cal and finally .50 caliber.
Yes, the.22 caliber rifle is perhaps the most common firearm in the US. The .22 cartridge is also used in handguns. Search Wilipedia for .22 Long rifle, and it will have information on the cartridge used by rifles and handguns. I have about 30 different .22 caliber rifles in my collection- they are accurate, inexpensive, ammuntion is not expensive, they have very little recoil, and my grandkids like to shoot them.
Both Shinsung and Sam Yang make a 50 caliber air rifle. The largest caliber Weinrauch makes is a .25 caliber.
Good rifle, good caliber for most uses. Did you have a specific question?
It is most likely to be a .32 caliber rifle since it uses .32 caliber ammo
