Back on topic of legal BB or bearing propelling device that would be legal where air guns are not. The goal is to have a device that will accurately shoot a BB or bearing 25 feet to neutralize the English Sparrows threatening my currently nesting bluebirds. There are two sparrow males hassling the bluebirds. Taking a mortally wounded bluebird out of a birdhouse with a hole pecked through an eye into its brain by a sparrow was not a pleasant experience. I use what traps and control measures I can, but would like to be able to knock the sparrow off a house or branch. I have a slingshot but my aim is terrible, never hit a thing.

Two questions: are there any CT limitations on slingshots, and does anyone know of a high tech slingshot with rifle stock, locking trigger that would be legal for this purpose here where due to nearness of other structures the air gun is not.
