I had a Pig do a "runaway gun" routine on me once...was firing from prone in short controlled bursts and took my finger off the trigger after going throughabout half the belt -but the pig just kept going "BANG-BANG-BANG"! I had to twist the belt to make it jam to get it to stop. ...interesting weapon but it was the only thing we had (never fired the M240 or M249...that was way after my time).
I miss her. sniff.
