UK <12 fp air rifle shooting is limited to <50 metres or whatever your model will allow.
If you wish to shoot at longer ranges and have a venue where it is safe to do you will need to go through the process of obtaining a FAC to own a capable air rifle. The FAC application is not a straight forward process so I am advised, needing
a history of a responsible interest in shooting, gun ownership security, an approved place of use etc. Coupled with this shooting clubs are closed at present due to covid and there is a wish within the authorisation to reduce the number of FAC licences and measures to delay the application process. Any views on this out there?
