Shotguns need to be kept securely as well. The Police are unlikely to issue anyone with a shotgun certificate (different to a firearms license) unless they have a securely fitted, BS approved cabinet which can not be seen by casual callers. The Police will come round when you apply for a SGC and try and pull the cabinet off the wall, too. The main difference is that a Shotgun Certificate allows you to buy and keep as many shotguns as you want, without having to re-apply for every new one you buy, although they must all be recorded on your certificate and you have to white to the police when you sell one to tell them where it has gone. You can also keep up to about 10,000 cartridges at home. Firearms (anything that takes a bullet) have to be applied for individually, and you have to prove you have the proper place to use them – you can’t just buy a sniper rifle because you fancy one. You will also be limited to a maximum number of rounds which have to be stored in a separate locked cabinet to your rifles.
To cut a long story short if the Police decide you are not a fit and proper person (for instance, if you get nicked for drinking and driving) they can take away your guns and revoke your license to keep them.
