I pulled out my AK last night and was doing some dry firing and practicing with the sling- transitioning to pistol. My wonderful wife says that I'm crazy.
I've also been reading the NATO War Emergency Surgery guide. It took me a little while, but I found it online for free. (Amazon wants to charge an arm and a leg for this.) Download it now and print it out. It gives some pretty intersting advice and a bunch of info on ballistics on various rounds and the damage it does on the human body. It has given me new perspective on the rounds that I plan to use and that I've purchased.
