You'll have to be very close for birdshot. I would go for buck shot. Still 122 shitniggers is a lot to take down with a gun, might be better to lure them all inside and just burn the place down.

In retrospect, if you could smother them with carbon monoxide or something, that would leave your home intact.

Nothing wrong with that, but the proper load for the task can make a world of difference. I've only ever seen birdshot recommended for genuine bird hunting, rodents, and snakes.
