I thought on an open ticket with conditions for clays, pest control and practical i could use it anywhere I have permission? But I have been wrong about many things! There is an element of having one just because I can, and you can't really lose much on a £700 gun. Also there is the warranty. If you have a failure of a s/h gun you lose everything or have to pass on a pup which I would not. Much the same arguments against fac air, but mine whilst occasionally playing up and me having learned to service most of it has been night and day more effective than my sub 12.
