I have a friend who actually owns it, and let me borrow the beast for a night.
Long story short, the cold weather made it shoot when my finger wasn't on the trigger. At that point, my hand was about 3 inches from the muzzle. This is what happened:

needless to say it hurt. a lot. And this was just at 300 fps. I'm glad I didn't have the regulator for 600 on it. This pic was from after two days. That was about a month ago.
After it healed and I could touch it again without opening the cut, I noticed a painful lump inside my hand. I went to a doctor friend at church this past Sunday and he took me to his office to check it out.
After about a half hour of digging, this came out.

I guess it's bound to happen with 150 bb/s coming at you.
Cool, right?
