I gave it to my Dad for a Father's Day present; he only fired it with black powder and wadding.

He touched it off once inadvertently pointed at an aluminum stepladder about 20 feet away - the paper wadding broke a side rail of the ladder.

I'm almost afraid to ask but where does your Dad get the black gunpowder?

In a jar at the local hardware store? :)
