Thanks Tipoc, the only thing that really gets me when watching gel vids, whether its Tnoutdoors or brassfetcher etc (scubaoz has a lot although not as good) is that the results dont account for bone. Which is where my quandary comes into play.
A heavier bullet will break and shatter the bone AND keep going, a lighter bullet may reflect off (and depending on the direction cause more damage) But to me stopping power depends on the wound cavity, so if shooting someone in the gut = cardiac arrest in their heart then the bullet (apparently 125 grain) will cause that. That to me = 1 shot stop
Thank you all for your input I really took the time to read every post so far and I have that much more to go from, which is not to say, I have learned alot!
