Just a quick public thank you to KevinF and IanF reference the huge amount of help they gave me regarding my FAC. It would appear I've an open ticket (haven't seen it yet as we're seperated by 550 miles - wifes sending me a photocopy) for .308 and .22. Basically what i asked for. Without Kevin and Ians help I'm sure things would not have gone so swimmingly.
Thanks also to Mike from Jelen Deer who provided me with a reference.
While I'm here I'd be as well saying cheers to the Tayside FLO who dealt with the application quickly and diligently.
Now all I need is a rifle....!
