Hollow points! for quick clean kills, and it's still no guarantee. I've had many of them crawl off with a HP through both ears, but I've had even more crawl away with head shots from solid points. I shot these two this morning, the big fox took a 36gr HP in the left ear and it exited his right eye taking a big hunk of his skull with it and he still crawled a good ten feet, I found him half way under a small brush pile. HP's are not a sure thing but the odds of them getting under cover or in a hole are far lower than with solid points.
