Many years ago at the age of 18 I had my very well used tubular receiver Stevens .22 LR go full auto. The fist time it happened only four or five rounds went blap. Scared the stuff out of me. I tore the rifle down and gave it a thorough cleaning. Midway through my next dump shooting session, I loaded 15 rounds in the tube, pulled the rifle to eye level and pulled back the bolt. When I realeased the bolt all 15 rounds went blaaaaaappppp! Without my ever touching the trigger. Loading another tube full resulted in the same thing. Let me tell you, that Stevens had one fast cyclic rate!
My dad called a local gunsmith who bought the gun from him for $50 rather than repairing it. To this day, I wonder exactly what the gunsmith did with that old Stevens.
