I like the heavier/bonded bullets, too, but only just in case I hit bone accidentally. Personally, I'd rather punch the ribs so I don't completely wreck a whole shoulder (or both) worth of meat. Any decent energy rifle is going to destroy the vitals, although it can suck having to move 300-400 lb any extra distance than you have to. They just don't tend to go far anyway. Like said, no wrong shot placement as long as its a quick, clean kill. Just another opinion/consideration.
