Well, I had a letter through from Avon and Somerset today, so there's me thinking it will say something like 'please re-do your variation application as you forgot to fill in ......' or whatever; I sent the paperwork off last Tuesday you see, so the department will have received it on Wednesday, and I was told a short while back that the current turnaround time for variations at A&S was 3-5 weeks.
Anyway, I was over the moon when I read 'please find enclosed your updated Firearm Certificate' with .243 rifle + .243 sound moderator added!
I am so pleased that I've got this back so soon, when I was prepared to be waiting weeks and weeks; I'll be writing to Avon and Somerset to say thanks for their prompt service.
As some of you will know, it was my first application for a deer-legal calibre, and I'm glad it's gone so smoothly - after seeking advice on here (thanks people!) I included a letter detailing the experience I have gained, a copy of my DSC1, references, etc., and it looks like it paid off.
Can't wait to buy a set up and get started!
