Since I am only 16 years old, I go to high school and the janetor had told me something very interesting. He said he had an old New Haven 12 gauge and he said it was old and worn out and it for some reason became fully automatic. He said if you weren't carefull while pulling the trigger all three shots would go aff one after the other. Has anyone ever heard of this before? He said he sold it cause it was becoming unsafe to be shooting fully auto.
