I never aim for behind the shoulder. Droppin deer without hitting shoulder or spine is'nt something the I've witnessed. My kid and ex wife always aim behind the shoulder and hit lung. I hate trying to find a deer that ran hard after shot and does'nt bleed. Brake down the shoulder and hit multple vitals at once. Shooting soft spots like behind the shoulder in my mind does'nt create as much energy collected from the bullet on impact and internally. Like zippin an arrow through them. Arrow shot deer behind tge shoulder more often than not make a strong run just like a bullet shot deer. It's hard to run with a broke leg, shoulder, or shoulders.
It's funny, I discovered everybody likes to chase the tang like bucks in rut and the tang really dont want all that bang. Just diflicted attention.
