In Scotland, if you have a Air Weapons Licence, it is a condition that you (or the club etc) are insured. But you don't have to have an AWL if you are using someone else's gun with their permission. It is possession (owning, storing or transporting) that is illegal without an AWL, not shooting. And before anyone asks, no one knows exactly what 'transporting' means. If you bring a gun to a shoot or a permission in your car, on your own, then there's not much doubt, but is taking one step with a borrowed gun transporting it? Two steps? Crossing the field? Only the Courts can decide and as far as I know they haven't had to do so yet.

Makes just about as much sense as some of the Covid rules....

Having said all that, I would never shoot without insurance, and never have, AWL or no AWL.
