We have air rifles but they won't even be on that list.
It's a pretty normal thing to have a shotgun in the countryside and you'd struggle to do much malicious damage with them. Firstly they're massive and obvious. You could pepper someone with shot if they were nearby but after two shots you have to reload so it's not really a mass damage weapon.
In the countryside there needs to be pest control for e.g. pigeons, rabbits etc, never mind shoots for pheasants and at clay pigeon ranges so 0.8% of the population sounds about right to me.
