RE: 22lr. shotshells
As most everyone has mentioned, use them for thier intended use, and they won't seem to suck so bad. They are loaded with #11 shot and simply aren't effective past 20 or 30 feet on small rodents!
Get a shotgun, at least a 4-10 to hunt doves with. The national average is about 1 dead dove in 7 shotshells. Now if everyoneusing shotguns can only kill 1 in 7, I think you'd be doing goodat killing 1 in 50 with a 22lr with shotshells.
