I have a squirrel problem and don't want to kill them, and it's not in season. Those varmints steal the bird feeders. I can shoot a pistol or rifle, need a BB rifle or pistol that is accurate to 25ft or so and don't have to pump a handle.

Live in the country and can shoot out the back rooms at the pests. They also get in the house garden in spring and summer.
I think they can be "trained." 22 rat shot would kill them so that's out.
