You're probably looking at the temporary cavity. At handgun velocities most tissues (with a few exceptions like the heart or the liver) move aside from the temporary cavity and then move back into place with little to no damage. It's usually only with a rifle round that the wound cavity rips muscle tissues etc. if you're interested, the link I keep posting with that picture http://www.ar15.com/ammo/project/Self_Defense_Ammo_FAQ/index.htm
is a very detailed article on the subject with a lot of other sources to back their info up in the article and on the website. Lots of before/after pics of JHPs and their mushrooms too if you like that kind of thing.
I can tell differences from bullet to bullet in that pic, but they're not as dramatic as people like to portray them.
I keep posting that pic so that I can do my part to educate the gun toting population sir. ;-) 1 thread at a time.........
