It's kind of a apples to oranges comparison. If you are just talking about foot #s, the edge will go to the 357mag w/ full power loads. Go +p in the 4" 45 & it's pretty much a wash. And it all means pretty much nothing.
"Given adequate penetration, a larger diameter bullet will have an edge in wounding effectiveness. It will damage a blood vessel the smaller projectile barely misses. The larger permanent cavity may lead to faster blood loss. Although such an edge clearly exists, its significance cannot be quantified".
