Everybody likes to talk about energy and that's great, but what you want to talk about is the energy to work conversion.
So here we have a 225gr JHP(I'm assuming good) and a 360 gr hard cast solid...your target is a mean, mad, tough, thick skinned, thick skilled Grizzly that now wants to kill you.
Let's assume he is 25 yards away. At >50 yards, you would be tripping a former friend, jumping back in the truck, going back to the cabin, etc.
With your ~1000lbs of energy, what do you want to do. Ideally, you want to penetrate into the innards, create a massive temporary wound cavity and exit blowing bone and tissue out the hole. Sorry, but 45 Colt won't do that to an animal much larger than a 50 yard Antelope or Whitetail Deer. So you must choose.
On a 225gr JHP, a 45 Colt will expand nicely and stop in the middle of the grizzly on a body shot. It used all its energy breaking through bone and expanding. It pooped out in the internals, possibly damaging the heart, but maybe not. The Grizzly now has full blood pressure and a pain in his side.
With a 360gr solid, it will expand almost none...maybe some nose deform hitting a bone. It should have energy left to exit causing massive bleeding and a dramatic loss in blood pressure....I'd go ahead and shoot twice trying to hit the heart this time.
The point is an exiting bullet should create a loss in blood pressure causing quick organ shutdown.
With either bullet, a hit to the heart or spine would be pretty quickly fatal. That is why the work done is more important than the energy in adequately powerful calipers.
Taylor tried to quantify that using diameter in his formulas because diameter alone will do more work going through the animal.
Why is 5.56 so deadly, but then sometimes not?? Because of work. Its velocity is so high that it rips the jacket off and blows up the lead core when it hits and goes through the first bone. If one of the 20+ shards goes through the heart, it will stop. If it goes through stomach and muscle, it will not...at least not quickly. The 62gr steel core just punches a hole doing minimal work.
