It is very simple.
The .357 has always been one of the best for bad guy shooting because bullets are fragile and open fast. But you get one lung, not two so you keep shooting.
Use a hard bullet and you need to empty the gun but then you also have over penetration, not good.
Deer and animals are different so bullet choice is far more important because you want to destroy TWO lungs so the fast opening, fragile bullet is out. The tiny entrance hole will not leave a blood trail either.
Small caliber bullets are light and though fast, stop fast. Go up in weight and use a very controlled expansion and they work for deer just fine---100% different then you want for a BG.
To compare any animal to a junked up jerk is a big mistake. But it is also wrong to think deer are fragile and fall down with any hit.
The big problem with the .357 for hunting is bullet selection and if you think the best self defense round will blow deer off their feet, you are in ga-ga land. It is the worst comparison you can make.
My opinion, the .44 mag is the best starting point for deer and up. Even the .44 works better with 300 gr to 330 gr bullets. Weight, penetration, enough energy to disrupt internals, two holes for blood trails, etc.
I feel a .357 is a great woodchuck gun and will never own another. It is just a weak sister that is too finicky for the bullet used.
Statistics show only a 50% recovery of deer shot with the .357.
Nothing has gotten tougher to kill but the little guns have not taken up the task because they can't.
The very best comments will be to hit the deer RIGHT THERE every time. It is so funny as to be ridiculous. Most revolver shooters can't hold a foot group at 50 yards! Shake them up with buck fever and look out!
It is not "hogwash", it is fact. Bigger kills animals better.
