Agree with most here... if you want your best chance at an exit, use a mono... but I wouldn't expect bang flops with behind the shoulder lung shots.
With that said, I love the 85gr Sierra GK HPBT. It kills way above its pay grade. I also love the 95gr NBT, so...
As stated before, the 90gr NAB is worth a look, too.
I'm a shoulder shooter - I'll give up some shoulder meat in exchange for knocking out their running gear. With that, a 75 yard death run after a top-of-the-lungs shot doesn't seem too bad to me. I've seen lung shot deer run a lot further than that - blood and no blood.
