A friend recently asked me what kind of .22 rimfire he should buy to hunt squirrels. His criteria is that it be less than $400. I haven't bought a .22 in awhile so thought I would ask you guys first to get us started in our search. He will want to mount a scope on it, so maybe make that recommendation too. I have good .22s but they are all over his price limit. I haven't looked at the less expensive ones recently so will appreciate your help.
