A handy A-Z guide to shooting terms | Shooting UK

We’ve put together a handy glossary of shooting terms that you’re likely to come across. Here’s what it all means.

A

Accidental discharge Sometimes called a “negligent discharge”. It is the unintentional firing of a rifle or gun

Action The mechanism of a rifle or gun by which it is loaded, fired and unloaded

Airgun A general term for any pistol or rifle that uses compressed air as a propellant. There are three main types of airgun, Spring-powered, precharged pneumatic and CO2 powered. See below for more details. In England and Wales air rifles under 12ft.lbs. and air pistols under 6ft.bs. do not require a licence. In Scotland all airguns require a licence

B

BB A small ball bearing used in some types of airgun, (usually CO2 powered) or a size of shot in shotgun cartridges used for large game

Bag The term for shot quarry

Ballistic co-efficient Measure of how streamlined a bullet is and how well it goes through the air

Beaters A group of people who walk in a line with gun dogs ahead, driving the game forward out of cover

Bluing or blacking Protective coating on the metal parts of a rifle or shotgun with a distinctive blue/black colour

Bore Interior diameter of the barrel of a firearm, or calibre of a shotgun

Bore line An imaginary line from the muzzle of a gun along the centre of a barrel

Bolt Action A type of action that uses a manually-operated bolt to unload and load a gun. Bolt actions are usually found on rifles, but they can be used on small shotguns, such as a .410

Brace The term for a pair of shot quarry. So two pheasants would be a brace of pheasants and so on

Breech End of the barrel nearest the shooter where a bullet, cartridge or pellet is loaded

C

Cannelure A groove or indent around the base of a cartridge case where the extractor takes hold. Bullets also have cannelures to enable them to be crimped into the case

Carbon dioxide Sometimes used as a propellent for low-powered airguns

Cartridges These propel the shot towards the target. There are different types of target for different quarry and the gun being used

Cast The angle of the stock (left or right) to the centre line of the bore, which enables the shooter’s eye to line up, with the centre line of the bore

Centrefire A cartridge with a primer placed in the centre of the cartridge. This type of cartridge is suited to high power ammunition

Chamber length Chamber lengths in shotguns are usually 2½, 2¾ or 3 inch (65, 70 and 76mm). You will need to know the chamber length of your gun before buying cartridges – if you use the wrong size you can seriously injure yourself and damage your gun

Choke Chokes are fitted to gun barrels to restrict the width which has the effecting of ‘focusing’ the shot on the target

Close season Specific times of year when it is illegal to shoot different quarry, to allow them to move to new grazing grounds and produce young

Cover The area in which the quarry hides. Cover can be woodland, hedgerows, crops (specific crops such as maize, kale or mustard can attract game and these are known as cover crops)

D

Damascus barrels An early way of making barrels by welding strips of metal together around a rod and forge welding them together. This created a beautiful effect, but the barrels are not very strong

Dominant eye This is the stronger eye and is usually the eye a person would favour when looking down a telescope

Driven shooting  The term for shooting when a line of beaters with dogs drive the game birds from their cover so they fly over the waiting Guns

Drop at heel, drop at comb, drop at toe These are measurements of how much the stock drops in certain places below the rib of the gun

Dry-firing Using an unloaded pistol or airgun to practice shooting techniques. Target shooters use it to build up muscle memory. Be warned, dry firing can damage the action on some firearms unless snap caps (see below) are used

E

Ear defenders These are vital to protect the shooter’s hearing when firing a shotgun or firearms

Ejector A mechanism that removes the cartridge from the breech of the gun after firing

Elevation The upward or downward adjustment of a sight

Etiquette

Shooting has its own etiquette which is basically common sense and good manners. The form is different if you’re gameshooting or clayshooting. Always treat other Guns and your host as you would like to be treated yourself and you won’t go far wrong. You can read our extensive and informative articles on shooting etiquette which should cover everything you need to know – from what to wear to how to respond to a shooting invitation. In the meantime, here are the basic 10 commandments of shooting

  • Always respond to a shoot invitation promptly whether you are planning to go or not
  • Put your mobile phone away
  • Dress appropriately for the day
  • Tip the gamekeeper
  • Listen carefully and attentively to the shoot briefing
  • Follow the shooting safety rules to the letter
  • Go to the peg you are assigned to – don’t hog the middle of the line
  • Don’t boast or brag about your bag
  • Don’t talk loudly when you’re on the peg and waiting for a drive and don’t bang your car door when you arrive
  • Write a thank-you letter afterwards, particularly if you want to be invited back

Eye relief The distance between the shooter’s eye and the ocular lens (the lens nearest the eye) of the scope

F

Felt wad This separates the powder in the shotgun cartridge from the shot and pushes the shot down the barrel after the powder has ignited. Made from wood fibre, it is biodegradable unlike a plastic wad

Ferreting   Ferrets are put down rabbit warrens to make the rabbits bolt outside into a waiting net. The rabbits are then shot immediately or dispatched humanely with a priest

Firearms certificate A licence needed to own firearms, or airguns over 12ft.lbs power. (See advice on how to get one)

Firing pin A small steel pin which strikes the metal primer of a cartridge to ignite the powder which then explodes pushing the bullet (rifle) or pellets (shotgun) out of the barrel

Fixed sights Sometimes called open sights, these are iron sights mounted on the rifle’s barrel

Flinch A nervous twitch caused by firing a firearm and is often caused by the shooter fearing the recoil of a firearm. It can ruin accuracy

Ft.lbs The way the energy output of a rifle or airgun is measured

Full-bore Usually refers to rifles larger than .22 calibre that use centre- fire (see above) ammunition

Full metal jacket The copper covering of a lead bullet that allows the barrel to be driven up the barrel faster than a pure lead bullet

G

Group size The measurement of the patter of shots on a target for rifles and pistols

Gun The term for the individual shooting a gun out in the field. Always with a capital G

Gun fit  The term used to fit a shotgun or rifle to an individual shooter’s body, so that the eye is aligned directly down the rib (shotgun) or scope (rifle). This produces much greater accuracy and usually minimizes the effect of recoil on the shooter

L

Leading The ‘gunking up’ of the lands and grooves in a rifled barrel (see below) from bullets or airgun pellets. This can affect accuracy

Let-off  The point at which the sears release the shot in a trigger mechanism. A crisp let-off means the trigger works rather like a switch and ‘creep’ refers to a more vague let-off point

Load  The number of shot pellets packed into a cartridge. This is measured in grams and known as the ‘total weight’ of the shot. Recoil will be heavier with a high load

Load  To put a cartridge into a firearm, or the composition of a cartridge

Lock, stock and barrel  The three main parts of a shotgun. The lock refers to the action

Lock time The time taken from the release of the sear by the trigger to the moment the primer is struck. In airguns it refers to the time taken from the release of the sear to the exiting of the pellet from the barrel

M

Magazine Part of a repeating rifle that stores ammunition ready for the next shot

Mildot This does not stand for “military” but refers to milliradian, which is a unitless measurement, similar to degrees

Mildot reticle A scope reticle designed around the measurement unit of a milliradian. This allows the shooter to calculate the distance of an object with known dimensions, helping range finding and accuracy

Minute of angle (MOA) Used by the military and target shooters and it is an angular measurement used as a reference for sight adjustment

Muzzle The end of a barrel

Muzzle energy The energy with which a projectile leaves the barrel, usually measured in ft.lbs.

Muzzle velocity The speed at which a bullet or pellet leaves the barrel

O

Objective lens Lens of a telescopic sight nearest the object being viewed

Ocular lens Lens on a telescopic sight nearest the shooter’s eye

Over-and-under A shotgun where the barrels are placed one above the other

Open sights Non-telescopic sights, sometimes called iron sights

Over-travel The amount of movement on the trigger after the sear has been released

P

Parallax error This occurs when the target image does not fall in the same optical plane as the reticle. This affects all scopes, but many have a parallax adjuster that focuses the scope at one range and aids accuracy. With high magnification scopes parallax error is particularly acute

Peg Where the Gun stands waiting to take a shot at the quarry. Pegs are each given numbers and Guns draw at random from cards numbered accordingly. Hogging the middle peg is considered bad form and each Gun will move to a different peg at the end of a drive

Pellet A projectile made of lead used in an airgun, which is usually shaped like a shuttlecock. Sometimes called a slug

Picking-up It is the job of gundogs and their handlers to pick up fallen game and track down wounded birds (and dispatch them humanely).

Plinking A name given to informal target shooting with an airgun

Priest An instrument used for dispatching injured game humanely

Primer A small charge fitted in the centre of a centre fire cartridge or around the rim of a rim fire to ignite the main charge in a cartridge

Proof Process of checking that that a firearm is safe which is usually done by firing a special test cartridge which exceeds the guns tolerances by 30%

Proof mark The mark that proves the gun is safe and has passed proof (see above)

Q

Quarry This is your target of your shot – which may be a clay pigeon, a game bird, a rabbit, vermin or a deer.

R

Recoil  The rearward movement of a rifle or shotgun when it is fired

Reloading  The process of refilling empty cartridge cases so they can be used again. This is done for economy and in the hope of increasing accuracy

Reticle  The crosshairs on a telescopic sight

Rifle  The barrels of this type of gun are rifled – marked with grooves which cause the bullet to spin, making it go further and hit more accurately. Rifles are used for killing quarry at a distance, cleanly and humanely. Ammunition is bullets and a firearms certificate (different from a shotgun licence) is required

Rough-shooting (see walked-up shooting)

S

Semi-automatic  A shotgun where cartridges are placed into a magazine which automatically loads the cartridges into the waiting chamber

Shot  Shot pellets come in a variety of sizes from 2mm-8.4mm in diameter. They are usually made from lead (although steel shot is a legal requirement for wildfowling). The larger the shot, the fewer pellets in the cartridge. Large shot travels with more energy and goes further so it gives a clean kill for large or distant targets

So in shot size high numbers equal small shot – with 9 being the smallest, going to 1 and then into letters (BB and SG is the largest shot available used for hunting large animals and vermin)

Shotgun A shotgun has single or double barrels and fires shot contained in cartridges, which are place in the chamber of the gun

Shotgun certificate  If you own a shotgun the law is that you need to be in possession of a valid shotgun certificate.  You can however apply for the certificate before you buy a gun. Certificates are currently valid for five years and you should allow several months for a certificate to be granted. Here’s how to apply for a shotgun certificate

Side-by-side  A shotgun where the barrels are literally placed side by side

Snapcap An inert cartridge used to release the tension on the firing pin spring of a shotgun or for dry-fire a rifle

T

Telescopic sight A sight which is rather like a telescope and magnifies the target

Tipping  It is customary to tip the keeper at the end of the day, who will divide up tips amongst the beaters and pickers-up. As an old-fashioned rule, it’s £30 for the first 100 birds and then £10 for every 100 after that. However, if the Gun has had a particularly good day then generosity should prevail

Trigger blade Device operated by the shooter’s finger that operates the trigger system to fire the gun

Trigger mechanism The device that uses sears to release the firing pin of a firearm, or release the mechanism of an airgun to fire the shot

W

Wad – packing that keeps the shot in position in the cartridge. Wad can be made from plastic, fibre or felt

Wad cutter A bullet or pellet with a flat nose used for target shooting because they produce neat holes on the target

Walked-up shooting. This is informal and consists of a handful of Guns, dogs and a gamekeeper. The group literally walk across fields and along hedges with the dogs going ahead, flushing out any game or rabbits around. This offers the hunters a challenging shot and the dogs then retrieve anything hit.  The Guns have to have good reflexes and be able to make decisions quickly  It is certainly a form of shooting that fully occupies the mind as the shooters have to be aware at all times of where everybody is and where the dogs are ranged. The small number of birds or rabbits shot are generally taken home to be cooked. In fact, this is shooting ‘living off the land’ and how many tenants used to feed their families back in the day

Alternatively walked-up shooting may be a form of pest control where corvids, rabbits and foxes are the quarry. Walked-up shooting can also be known as Rough shooting 

Weight. Generally heavier guns absorb recoil better. A side-by-side is usually lighter than an over-and under

Windage The lateral adjustment of a sight

Y

Young Shots. Shooting youngsters are collectively known as Young Shots – a term that usually covers them up until the age of 18

Z

Zero The range at which the point of aim and the point of impact coincide

Zoom A term that describes the magnification of a scope
