Ha. Yes. A cousin had a Ruger 10/22 that hed converted like that. Hed filed down something.
Once you pulled the trigger, itd fire until it ran out of ammo, jammed, or until you grabbed the bolt.
I fired it one time (I was fully aware of how it would hang) and as I rotated it to try and grab the bolt, a cartridge was ejected down the neck of my shirt somehow. It was hot and got lodged between me and the waistband of my pants. I thought Id somehow managed to shoot myself (ricochet or something) in the bladder area.
Years later its sort of funny, but at the time it scared the crap out of me.
Like the Old Man said its a good way to mess up a perfectly good little rifle.
