I tell you what.., I've almost did it just by closing the barrel on my EVO too fast. I was holding the action with the corner of my right thumb hanging out just a litte close to the breech and it got caught by the closing breech block corner & opening a nasty but no stiches needed patch pinch/cut not far different from this chap. It did remind me that keeping hose digits clear & holding the barrel are VERY VERY important.
