Nope, no such thing as "more fatal" is there? That is like saying one deer is "more dead" than another... Couldn't resist that one.

I actually disagree with most, in that by far for me, high lunghits have brought my deer down the quickest. Regardless of opinion on the best part of the lungs, I am sure that some areas of the lungs have a higher density of vessels. I think you could make a case for a difference in effectiveness between lungs fully inflated at impact vs. deflated at impact as well.

I know for darn sure there is a difference in effectiveness on liver hits.I have had liver hits die in minutes and have some last between 8-12 hours.
