I'll tell on myself first.....only to help rookies out there. I some how got distracted when changing from pistol powder to rifle powder. I guess I didn't clean all the pistol powder out of my powder measurer. At the range the ol 6mm nearly knocked me off the shooting bench. The case wouldn't let the bolt release and a whole raft of problems happened. My rem model 600 never shot quite as good after that day. I'm lucky I didn't kill myself........ Now go ahead tell on yourself don't leave me thinking I'm the only idiot in this forum.
