You want to be >1,000ft lbs of energy for deer. A 300 with subsonics will only produce ~500ft lbs at the muzzle. Really shouldn't use that for deer.
I've heard that 1000 ft lbs number my whole life.
It's horseshit.
Does an arrow with a broadhead produce 1000 ft lbs? No, not even close.
A bullet designed to expand at sub velocities and good shot placement will kill a deer.
