A Minnesota man is in trouble after trying to use a .38 to kill a bat that got into his home. Apparently the bullets penetrated the walls of a nearby townhouse. If you insist on using a projectile weapon to kill a bat, I’d suggest an air gun. But really, bludgeons work fine on bats. When I had one in the house once, I just threw a trash can over it, scooped it up, and let it outside.
