Don't be put off mate it is all fairly straight forward, you will need some land to shoot on with written permission, or to be a member of an approved club with FAC clearance, you will need a security device, if you are planning on more than one gun then a cabinet will be needed, but for one gun there are other cheaper options, talk to your local gunshop.
The paperwork is easy, you will need a set of passport photos, you sign two, and your two referees sign one each. you will need two referees who have known you a while, but not family, I used an old school friend, and my supervisor at work, they also have to fill in a small form each. fill in your form and send it all off with your cheque. give it a week and then phone the FLO too make sure it has arrived, this will also get it to the top of the pile, offer to meet him at the shooting site, and arrange for his home security visit.
then if you have done your bit rightit should be job done.
Good luck.
