I have a quick question and hope that I can explain it well enough. A close friend was out shooting in the rain when one of the rounds failed to exit the barrel. When he opened the bolt the pressure of the round forced the bolt from the rifle with enough force to puncture his abdomen. I have been told that it is possible for water to build up around the front of the bullet and not letting it release from the casing causing the pressure to build and blowing the bolt out. Does anyone know if this is possible and if so how that small amount of water could cause this?
