CCI shot shells for the .22 are the best there is, and actually they are very good on snakes/rodents out to about 30 feet, but more realistically about 15 feet. Use some common sense, there is just so many shot that can be fitted in a 22 size capsule. They are in a capsule because the rifling in a barrel absolutely destroys an effective pattern if not.
If you would like to see a pattern just put up a piece of newspaper, step back (some distance) and fire away.
This shell was basically intended for snakes/rats at close range, thats it!

As the guy above said, if you want to shoot doves ( with reliability), use a shotgun.

Good luck.
