Well, I used to have this bb gun.I was around 13 or so.It had a bigger barrel case around the internal rifled barrel.There was about an inch difference in length.So I was playing around 1 day and set a 22 bullet down into the barrel case,and it set right on the internal barrel.I thought ,boy I could fire a bb at this and it would make it go off.I tested my hypothesis and it proved correct.You could in fact set a 22 bullet on there and fire it up in the air.So a couple weeks later me and my buddies were walking to their house through the woods with our bb guns,it was very cold and covered with snow.So I pull out a 22 shell put it in the end of my gun, point it up,and fire.Immediately I feel a stinging in my neck,I reach down and there's blood,alot of blood.So I figure that the bb bounced off the bullet and ricocheted back and hit me in the neck.Well of course I didn't want to go home and explain this,so we walk on to my buddies house.By the time I got there the blood had soaked all the way down my body to my pants,ruined shirt,but the blood had stopped.So I borrow a shirt from my buddy and call my mom to come get me.On the way home I make sure not to face her ,and she never knows anything about it. FF 3 years.Me and my sister are on the way to school.We get in a bad car accident and must be taken to the hospital for xrays and such.So we're waiting for the doctor to come in,me my sister and my mom.The doctor comes in and says no injuries,but they made a discovery in my neck.Plops the xrays up on the board,low and behold a 22 bullet is enbedded in the middle of my neck.Everything clicks together real quick,and the story comes out.I had shot myself in the neck with a 22,and thought it was a bb.The DR said it should come out,but it was so close to my major artery that he would not go in and get it.I missed killing myself by mm's.
