I've seen deer and elk both go a lot longer than 75 yards with a perfect double lung shot. And I've seen both drop right there or very close.
Read my post again: " A deer shot through both lungs seldom runs more than 75 yards.' The key word is
seldom and i stand by my statement
.
For many years i tracked and recovered wounded deer and elk for other hunters. Yep, i've seen a very few deer and elk shot through both lungs go 200 yards. Most of the deer and elk i recovered for other hunters had been gut shot.
For the most part i will continue to shoot deer in the boiler room like i have for the past 65 years. It works for me and i don't like to ruin meat.
