Rap, you just fell foul of another of my points: changing the subject to mediaeval archery doesn't let guns off the hook! And claiming that just because cartridges are physical, it makes them natural is the largesse of a birthday, I guess. I've heard of a gum-tree, but never a gun-tree. The closest I can get is the offspring of a horse, which if argued would mean Samuel was hung - as opposed to hanged, which is what happened to many of his clients.
