Is a 6.5 PRC enough? Do I need a 7mm?

No it’s the one that thinks knockdown power, ft lbs of energy and large bullet diameter is what kills things.

If a bullets energy and size don’t kill animals, then what does?

Bullet construction, and enough speed that the bullet performs correctly when an animal is struck by it in the vitals. It’s why a 77gr bullet at 1800fps will kill an elk, even though it falls well short of the 1500ftlbs of energy rule touted as gospel for so long. In fact, this .223 load has only about a third of that.

Yea, I’m not stating the specific amount of energy required to kill different animals. But, in the end, it is literally energy from the bullet transferred to the animal that causes them to die. The debate is how much, and where the energy is dissipated.
