I agree. Stricter controls on the purchase and ownership of Air Rifles would be of a benefit to the Airgunning community. A License (Not FAC IMO) would be good to carry with you along with your written permission just in case the boys in blue did turn up asking questions. It is a pity that the mindless and careless do give the more resposible airgunners a bad name, but that just seems to be the way of it.
I think this would be the best idea, not as strict as an fac but some sort of licence
