The bolt should stop if you do that and not hurt.... I tested it out on my Creed and Mini and it makes you jump but the bolt does what it is meant to do and stop..Or with no air attached stick your finger in the breach and pull trigger, il stress the NO air though or your name will be franky 3 fingers. Happened to me once, finger down feedneck, bang, it was like my mini turned into an ill tempered snapping turtle on steroids. X
