No good, you have to get rid of the hiccups to take the shot, in my experience. It's not like sawing someone's head off. And exploding rounds are no good for domestic wetwork, for a variety of reasons, mostly having to do with a) getting away, and b) deniability. They're OK for hot zones, because anyone can get anything. It's anarchy. Here, you should use ammo any schlub could buy from Wal-Mart so as not to raise a red flag. I mean, name one major job that was done with illegal ammo here in the States. Not lately!
Also, explosive tips sometimes blow up inside body armor, which isn't what you want.
Best round ever: .22 short, and get in close. Definitely not my thing, though! I prefer to phone it in.
