well that sucks, I grew up in Warwickshire and remember it as being a great outlet for youthful stupidity. I encouraged both my sons to have that kind of fun but to exercise reasonable caution. they know the safe use of firearms and how much black powder to put in a golf ball mortar without fragmenting the golf ball.
How amazing! I grew up in Warwickshire too, and I can testify too as to the outlet it provided for young boys!
