It's a devastingly deadly shot IF you hit what you need to, you have plenty to hit there, heart, one lung, major arteries leading from heart, diaphram and liver

There's also major bone structure to avoid, sternum and shoulders.

There is a soft spot above the sternum, I've talked to elk hunters/guides who say take this shot any chance you get if you know where the softball sized area is and can hit it.

For the record, I've never taken it. Well with a bow, I have with a gun
