I have a Ruger 10/22 carbine .22 LR with a 3-9 scope on it, would this be a good fox gun?my dad thinks it wouldnt be enough to take one down, but he doesnt hunt or shoot so he isnt a very good source. if its just barely enough gun,were should i shoot them. Imjust looking for a few skins to hang up at my camp, they dont need to be perfect so if i have to hit them in the head, i will.
