I filled out land useage form and all details of shooting club,club secretary's name and phone number etc etc,they seem to do anything to slow down or prevent you having a firearm,I've had firearms for over 13 years now,they do my head in.
This is pretty standard stuff mate - normally they will telephone you rather than go to the effort of sending a letter - maybe they did call but you missed it?
The main reason you've run into this problem is the fact you are after two .30 cal rifles - your 30-06 uses the same heads as your proposed 308,
I have experience with this myself when I requested a 22-250 and a 223.
I spent over an hour and three phone calls speaking with the licensing department about why i wanted two .22 calibre centre fires.
Basically they can't get their head around the fact that they are different, because on the list they use they are the same - if you see what i mean.
I got advise from BASC on this and it is right, they have to follow a procedure and that is what they are doing here.
Depending on what you say, will depend on the outcome.
The fact you have put target use may not wash, because in the same breath you have put fox, deer etc.
My advice to you, is to put in your letter quite clearly that you intend to fit one of the .30 cal rifles with a dedicated night vision unit, and the other with a dedicated day scope.
Obviously this is a very good reason for you to want to possess both rifles because you'd have to rezero the rifle each time you wanted to use night vision unit if you only had the one rifle.
The fact you wish to use the 308 on a range only reinforces your genuine reason to possess both rifles.
I hope that the above helps, and that I haven't just told you something you already knew.
