Here’s a suggestion - get the 10/22 and the box of ammo with it, and put it away for when you need it.
Then buy a Crosman 1077, an extra magazine, a case of pellets and a case of CO2 cartridges.
The 1077 is a 10/22 clone. It is a 12 shot repeater. You’ll get about 36-40 shots out of a CO2 cartridge.
