Larson your right!, be careful "scaring" animals with these new guns, Most of them them have a lot of "power" and the BB will go into the skin,
I agree with Larson, buy a soft pellet gun,, Also Aim for hind quarters, NOT neck/face area.
Or if you have a big problem, use a paintball gun and just shoot close by, the noise and paint spray will scare them too.( This is a little pricey, but effective)
