in total, or a shotgun with separate chambers (which would need to also be multi-barrelled). For a shotgun to qualify as a section 2 shotgun, it must meet the following criteria: (a) has a barrel not less than in length and does not have any barrel with a bore more than in diameter; (b) either has no magazine or has a non-detachable magazine not capable of holding more than two cartridges; (c) is not a revolver gun. Prior to a SGC being issued an interview is conducted with the local Firearms Officer, in the past this was a duty undertaken by the local police although more recently this function has been "contracted out" to civilian staff. The officer will check the location and suitability of the gun safe that is to be used for storage and conduct a general interview to establish the reasons behind the applicant requiring a SGC. An SGC holder can own any number of shotguns meeting these requirements so long as he/she can store them securely. No certificate is required to own shotgun ammunition, but one is required to buy it. There is no restriction on the amount of shotgun ammunition that can be bought or owned. There are also no rules regarding the storage of ammunition. However, shotgun ammunition which contains fewer than 6 projectiles requires a section 1 Firearms Certificate (FAC). Shotguns with a magazine capacity greater than 2 rounds are also considered to be section 1 firearms and, as such, require an FAC to own. An FAC costs £50 but is much more restrictive than an SGC. The applicant must nominate two referees who are known to the applicant to vouch for his or her character; a new 'variation' is required for each new caliber of gun to be owned; limits are set on how much ammunition a person can own at any one time; and an FAC can be denied if the applicant does not have sufficient 'good reason'. 'Good reason' generally means hunting, collecting, or target shooting – though other reasons may be acceptable. Personal defense is not an acceptable reason. Any pump-action or semi-automatic smoothbore gun (such as a shotgun) with a barrel length of less than 24 inches or total length of less than 40 inches is considered to be a section 5 firearm, that is, one that is subject to general prohibition, unless it is chambered for .22
