The bolt contains the firing pin and extractor.īore This refers to the inside of the gun's barrel. Acting in line with the bore it locks the cartridge into place ready for firing. It is a mixture of potassium nitrate (otherwise known as saltpetre), sulphur and charcoal.īolt The bolt is used to push forward and extract the cartridge. Berdan primed cases are not easily reloadable, and are found commonly in military ammunition.īipod Attached to the fore-end of the rifle, a two legged support which is used mainly in long-range rifle shooting.īlack powder This is the oldest form of gun powder, used in muzzle loaders and early cartridges. The anvil in a Berdan primer is part of the cartridge case. It can be recognised by having three off-centre flash holes. This is either when testing the gun's accuracy, or as a form of competition.īerdanCentre fire primer type. (See Shotguns).īedding The way that the barrel and action are fixed to the stock.īenchrest This refers to the use of a table or bench to support a gun. Terminal ballistics studies the interaction of the projectile with its target.īarrel Tube through which bullet is projected.īattue Type of clay pigeon. External ballistics is the study of the projectile as it travels through the air. Internal/ interior ballistics looks at the initial processes that accelerate the projectile, from primer ignition to the bullet exiting the barrel. It is a fixed metallic point which the priming compound is crushed against when struck by the firing pin.Īutomatic Ball Trap Clay pigeon shooting discipline.īall Projectile fired from muzzle loaders.īallistic co-efficient (BC) This is a measurement of a body's ability to overcome air resistance in flight, a bullet with a high BC number will meet less air resistance than one with a lower number, and will therefore travel further.īallistics The science that deals with the motion and behaviour of projectiles. Screwed to the stock, it contains all the parts necessary to fire the cartridge and to attach the barrels.Īirgun A gun that uses air or compressed gas to fire its projectile.Īnvil Referring to primers. Below is a list of common words and a brief explanation of their meaning.Īction Used to describe the firearm's mechanism, by which it is loaded, locked, fired and unloaded. Using real incidents, you’ll learn the mind and body’s limitations and normal response when using force.There are a variety of terms that you will hear if you take up shooting. In addition, scientific factors affecting human performance during dynamic and evolving force events will be examined as well as the impact of video on investigations and public perception.ĭiscover the Science of Police and Human Performance under Stress. From practical application on the street for line officers through force investigations, students will develop working knowledge of the constitutional parameters for using force. Focusing on Supreme Court decisions and applicable state statutes this course strives to help limit your exposure to excessive and unnecessary uses of force and as a result, avoid litigation. This dynamic, eight-hour program is a reality-based course that separates fact from fiction about Case Law, The Use of Force and Human Performance Under Stress.
