My Dad has bought a Crosman 2250 (ratcatcher), I was wondering which a close range <20 yard head shot, what vermin can be dispatched with it? I'm thinking rats and pigeon should be fine, unsure about squirrel and rabbit. Technically, with a .22 only 380fps is required for a rabbit and 300 for squirrel and pigeon (unsure if this is for head shots or body shots) and the muzzle velocity of the gun is meant to be 550 fps, obviously during flight it looses power, but how much?
If it's going to be underpowered i don't want to cause unnecessary pain to the animal.
It comes with a (poor) 15 x
