Like 500 Grains, not every brain shot has been perfect. Most imperfectly brained elephants went down allowing me a follow up brain shot. When they didn't drop they got a heart lung from me and also the PH.

Using a double rifle lets you get off the second shot very quickly when required.

I'm sure that under some circumstances I would take a first shot crack at the heart, but haven't encountered those cicumstances. The furthest a heart/lung shot elephant has gone for me is about fifty yards, but they all had two in the heart/lungs.
