Calibres, cartridges and quarry: advice for firearms enquiry officers
The cartridge; rimfire or centrefire
Only four cartridges are commonly found in rimfire. These are .17 HMR (Hornady Magnum rimfire), .22 LR (long-rifle), .22 WMR (Winchester Magnum rimfire), and 9mm rimfire, the latter appearing in shotguns.
Rimfire cartridges are easily recognisable by the head of the cartridge (opposite end to the bullet) which is smooth and flat. The priming compound is contained within the rim (hence the name) and is ignited by the firing pin crushing the rim of the case against the rifle’s chamber.
Naturally, the brass must be thin to allow the firing pin to crush it. This design limitation means rimfire cartridges will be low pressure compared with centrefire cartridges. Due to the relatively low muzzle energies produced, rimfire cartridges are seldom used for any quarry larger than rabbit/hare, and fox at close range.
Ease of manufacture also makes rimfire cartridges cheaper than their centrefire counterparts. This adds to their attractiveness to vermin controllers.
Centrefire cartridges have a separate primer which is pressed into a cup in the centre of the cartridge head. The .223 Remington is a common example of a centrefire cartridge. The brass is substantially thicker than its rimfire counter parts which allows much higher pressure (and therefore, muzzle energy) to be safely generated. The primers are usually replaceable allowing the brass to be reused.
Which calibre?
Calibre describes the bore diameter of a firearm. The rifling is usually measured from land to land as per British military convention, but this can vary on rifles of other origin.
It should be noted that calibre is distinct from cartridge. The former describes bore dimension, whereas the latter describes ammunition.
Both calibre and cartridge are largely a matter of personal choice, provided the applicant’s choice meets any minimum legal requirements. As section 10.40 of Home Office guidance says:
“Most firearm certificate holders possess firearms for reasons of their profession, sport recreation, or collecting, study or research and may properly wish to exercise discretion as to what types of firearms they choose for these purposes.”
The Home Office also provide a table at the end of chapter 13 to assist with judging the suitability of rifle cartridges for different quarry species. The examples given are limited. An extended version has been produced below to assist with decision making. Data is drawn from Cartridges of the World, 13th and 15th editions.
Within the below table, fields highlighted in green confirm that the cartridge is capable of killing the quarry humanely and legally.
Amber fields indicate the cartridge may or may not meet the required standards, depending on the load used. For example, .243 is usually acceptable for shooting large deer species, but some loadings may contain bullet weights that are too light. Likewise, some cartridges, such as .303 British, may not meet the required velocity for roe deer in Scotland (2,450 ft./sec.).
Fields coloured red determine that the cartridge is unsuitable. In the case of .22 LR, the Home Office advise it should only be used on foxes at close range and when controlling them around farm buildings.

Sound moderators
As the name suggests, sound moderators are an accessory for reducing the noise produced by firing. This might be required to protect the hearing of persons nearby, to prevent livestock becoming panicked, or to reduce the dispersing effect gun fire has on quarry in the area.
As per section 13.77 of Home Office guidance, ‘good reason’ for a rifle usually implies ‘good reason’ for a sound moderator.
Licensing officers should also note that integral sound moderators do not require a separate authority (Broome v Walter, 1989). Sound moderators for sub-12 ft./lbs. air rifles and section 2 shotguns are not caught by section 57(1)(d), and therefore, do not require any authority to purchase or possess.
Land inspections
Land should be passed for the maximum calibre it can safely sustain, not what the applicant has applied for. Maximum calibre should be entered onto the land register within NFLMS.
Chapter 13.12 of Home Office guidance gives some guidance on land inspections and what factors should be considered. Where the officer inspecting the land lacks appropriate expertise, input from local shooters, stalkers and game keepers should be sought.
