If I was worried about pass throughs or slugs leaving the scene, I'd go with some tack driving speedster that would pretty well shatter on impact. The heavier ones slugs the greater the chance they'll keep on trucking. With safe practices, however, one should be fine with anything.
Edited to add: Given ones limited space, he might want to assure a near instant knock down depending on whether neighbors are amenable or not to a follow up chase if/when a victim makes off of ones property. Regardless of choice, I'd try to break them down on the spot. Given the suggested ranges, good shot placement should be pretty easy on standing game.
Good luck,
