It's hard to see the justification in needing to put a s58 on ticket just to fire once in a blue moon just for fun when you already hold an fac and bp licence et al for far more powerful weapons. But then you see these piss takers insuring a beat up old banger with an "all other vehicles not owned etc" clause and proceed to drive around in a souped up racer which they could never afford to insure which "belongs to a friend".
