I took my newly restored Remington Model F Trap to the trap range on the weekend. I was shooting my own rolled 2 1/2 inch 3 1/2 drams blackpowder shells. I was stopped half way through the round by the club officials asking if I was using magnum loads since magnum loads are not allowed on the course. The different sound and the smoke had got their attention. I explained the gun and the loads and all was well. They had never seen anyone using blackpowder loads at the club before.

Nothing is foolproof to a sufficiently talented fool.
