My understanding is that you may fire a blank firing weapon on your own property - but be prepared to welcome an armed response team if your neighbours are of the jumpy type.
Usually show organisers state if blank firing weapons are alllowed to be discharged. And point of note is that the gun should be side venting not vent from the end of barrel.
you do not need a licence to own it or to buy the blanks.
Hang on Jerry is here and knows much more about it than me.........

What Sue has put about covers it, part from not sure about transportation to a show etc....
