I found this thread by accident today after doing a Yahoo search for stopping power / wound ballisics.
Just discovered recently that I shoot 158 gr. .357 mag rounds more accurately than I shoot the 125 gr. variety (out of my Ruger GP-100, 4"), and I wanted to see if there was any data on their relative effectiveness in self-defense applications (in HP design). From what I've read so far, there seems to be no consenus.
Assuming identical accuracy, of course.
