Hello , I'm just about to apply for my shotgun certificate , but there's one thing I'm wanting to know I'm 18 still living in same house with Mam and dad have no intention of moving as I'd rather spend money on guns haha , all I'm wanting to know is if im allowed to keep my gun in dads cabinet with his rather than having two in one house as it wouldn't be very convenient, just wondered if there's any rules about this and things you can and can't do , thanks
