Stan: There is a small shop at one of the local clubs. Reminds me of my first double purchase. I was looking hard at this Zoli in a shop and they asked me if I wanted to fire it. I said sure and we went behind the store, the guy loaded two shells, and boom! Massive recoil, and they are all laughing. Guy had loaded two magnum turkey loads as a joke.
