Re: use aTo Kill A Mockingbird
IF - & notice I said "IF" - you did hit him with the .22, he'd drop dead on the spot & there's a pretty good chance that somebody else within 1 mile of where you fired the bullet would also! The 'bullet' has to come down somewhere & that bird's not gonna stop its flight (or even slow it).
So, put that pistol down & back away, Janel!
IF - & notice I said "IF" - you use the 12-guage, even at close range there's a chance you'll miss that tiny an object what with the disbursement pattern of the shot...but, the shot will hit something somewhere - &, unless, your backyard is bigger than the normal city lot, you're gonna hit your neighbor's house or car or boat (or your own)
So, put down the shotgun & back away, Janel!
Get an air rifle or pellet gun & pop rounds at him until you finally get tired! Just make sure you're shooting them upwards at an angle, not towards the neighbor's - I've an air rifle that has the same stopping & destructive power of a .22 - just not the distance.
Or, better yet, pay a neighborhood kid to pop it with his beebee gun!
