What Brasso said. and more ...
Wild creatures (including Goblins on drugs) don't fall down because they think they are hurt. That's because they don't think. They are creatures of habit and instinct. When they are scared, they run. Hard. They pour it on. They don't know they are hurt. They don't drop until their system won't support the exertion. That is usually a few seconds from actual death.
I use Blue Dot-powered 158 gr semi-jacketed hollow points for everything in my .357 because I think it kills the quickest, which is more humane in the case of hunting and safer in the case of self defense.
Slightly heavier flat points would probably be better. But a 125 gr bullet go through a BG and he not even notice it? I don't think so. Not jacketed hollow-points commercially available today. Not have time to expand? Depends.
I shot a small whitetail buck (150 lbs), broadside, in Florida a few years back with a 125 gr JHP at 65 steps. It went in between two ribs and came out on the other side between two ribs. NO EXPANSION. No bullet fragments and no jacket could be found. Little buck ran about sixty yards. 'Thought I had lost it. This load was shot out of a Ruger Blackhawk and had clocked 1640 fps, avg, at the range.
After that I went to 158. The next critter was a 120 lb wild hog at 35 steps distance (about half that of the FL buck, I admit). He rolled. 'Got up and ran about 50 ft, then fell over. Dead as a rock when I got to him. Exit wound was a little less than two inches across.
This may be more of a lesson about shot distance with a .357, but I shoot the 158s.
