A pellet gun would’ve solved the problem fast. But of course this is the UK where the government thinks the people cannot be trusted with even that.
they can have pellet rifles there, but they are restricted as far as feet per second go i believe- here i n the states- pellet guns are the way to go- with many shooting over the speed of sound barrier- (Though you can crank that down to decrease the sound- pellets shoot the nicest @ about 870 fps or so anyways)
