I have been curious about state regulations on this. Air rifles are mentioned but their use in all situations are not defined. I would like to use my trusty Sheridan to take some rabbit and squirrels. And I think my son would have interest in this as well. In some of the state parks there are skeet ranges and if not in use for skeet, why not use an air rifle?
The fun thing about air rifles is that on some models you can vary the power and be sure of your backstop. I shoot in my basement. An archery bag target backed up by 3/4 inch ply wood will stop my pellets. There are types of knockdown traps you can buy that do a good job.
