I do agree with finding a round other than FMJ that expands well. .......... Anyway, find a good round that expands pretty well. I plan to do the same. Probably Hornady for myself.
I kinda have to disagree with your bullet vs arrow comparison. Arrows tipped with razor sharp broadheads kill by cutting major blood vessels, both arteries and veins. This causes massive blood loss, reduced blood pressure, and loss of oxygen to the brain. This process is known as hemorrhagic shock.
Bullets kill by high energy impact that crushes both bone and tissue. They often immobilize animals by breaking major bones, and shocking the complete neural system.
Im studying to be a wildlife veterinarian up here in Alaska, and I have saved animals that have been shot by small caliber guns that didn't have enough energy to break heavy boned, thick skinned animals.
We humans are thin skinned and most 223 bullets are made for humans, not animals with thick hides, etc.
Sure, a 223 will kill deer and big game animals, but bullet placement is a priority, where a larger caliber can do it more easily.
