A simple mistake that will be easily, and quickly, remedied by the department.
On receiving my recent renewal I found that the new authorities I had requested were listed as "7x64 Bolt Action Rifle" and "Small Bore Moderator". The office is reasonably close to where I live so I drove through and had a quick chat with one of the people there to highlight the mistake. She apologised, asked for my ticket and said "back in 5 minutes, I will just go check the paperwork". In less time than stated she was back, apologised again and handed over my shiny, new FAC with the correct moderator listed.
From door to door I was in the Police Station for less than 10 minutes.
