True, a can of stinky worms has been opened again ...
But in this case the OP has it right. He's worried about overpenetration that can risk his neighbor's life. That's the problem with living in an apartment. And I agree that birdshot at room distance is more than enough to get the job done.
I'd rather have a guy like the OP living next to me than some brain dead zombie killer loaded up with slugs.
