Study Notes
Firearm Basics
- A firearm utilizes pressure from burning powder to propel a projectile through a metal tube.
- Modern firearms consist of three main components: action, stock, and barrel.
Action
- The action is the central mechanism of a firearm, responsible for loading, firing, and ejecting cartridges.
- Muzzleloaders feature locks instead of traditional actions.
Stock
- The stock serves as the firearm's handle and is typically made from wood or synthetic materials.
Barrel
- The barrel is the metal tube where the projectile travels; rifle and handgun barrels use bullets, while shotguns use shot.
Chamber and Bore
- The chamber holds the cartridge or shotshell until firing, while the bore is the interior of the barrel through which the projectile passes.
Firing Pin and Receiver
- The firing pin strikes the cartridge's primer to ignite it.
- The receiver houses the operational pieces of the action.
Ammunition Components
- Cartridges contain a case, primer, gunpowder, and projectile; shotshells include these plus a wad.
Case and Primer
- The case holds all ammunition components and is often made of materials like brass or plastic.
- Primers are explosive compounds that ignite the gunpowder, differentiating between rimfire (located in the rim) and centerfire (located centrally).
Gunpowder Functionality
- Gunpowder burns rapidly to create expanding gas, propelling the projectile. Modern smokeless powder is safer than black powder.
Projectiles
- Projectiles include bullets (for rifles and handguns), slugs (for shotguns), and shot (small pellets fired from shotguns).
- Wad is used in shot-shells to separate powder from shot, preventing gas loss.
Bullet Types
- Hunting bullets may have soft or hollow points designed to expand upon impact.
- Target bullets are often solid points, creating small holes.
Rifle and Handgun Bullets
- Common rifle bullets include pointed soft point, rounded soft point, protected tip, and full metal jacket.
- Handgun bullet types include round-nose lead, full metal jacket, semi-wadcutter, hollow point, and wadcutter.
Types of Ammunition
- Cartridges are for rifles and handguns; shotshells are for shotguns, both containing necessary components for firing.
- Centerfire ammunition features primers in the case center, reloadable, while rimfire has them at the rim, limited to low pressure, and non-reloadable.
Gauge and Shell Length
- Gauge denotes the bore diameter of shotguns, determined by how many lead balls of equal diameter weigh one pound.
- Shotgun shells can vary in length, commonly 2 ¾ inch, 3 inch, or 3 ½ inch.
Magnum Shells and Shot Sizes
- "Magnum" shells contain more shot or gunpowder than regular shells.
- Shot size is inversely related to the numbered size; smaller shot numbers indicate larger size.
Trigger Functionality
- Pulling the trigger activates the firing pin to strike the primer, igniting gunpowder, generating gas rapidly that forces the projectile out of the barrel.
Firearm Operations
- Operating the lever, bolt, or forend ejects spent cartridges, chambers new rounds, and cocks the firearm.
Single-action vs Double-action
- Single-action firearms require manual cocking of the hammer to fire, while double-action firearms cock and release the hammer with a single trigger pull.
Caliber
- Caliber specifies the size of a firearm's bore and associated cartridges; measured by diameter from land to opposite land.
Matching Ammunition and Firearms
- Each firearm is designed for specific cartridges; ammunition must match the firearm's data stamp. Bore sizes of the same caliber are not interchangeable.
Hang Fires and Misfires
- Hang fires involve a delay in firing after the firing pin strikes, often due to faulty components.
- Misfires occur when the primer fails to ignite the powder.
Shotgun Classification
- Shotguns are classified by gauge, which relates to bore diameter and shot-shell sizing; smaller gauge numbers indicate larger bores.
Marking and Identification
- Shotgun gauge is marked on both the barrel and shell packaging for identification.
