Study Notes
Objectives of Ammunition Study
- Understand different types of ammunition.
- Identify various parts of ammunition.
- Recognize the significance of ammunition in ballistics.
History of Ammunition
- Early ammunition included loose powder and irregular projectiles.
- By the 15th century, standardized ammunition utilized black powder (charcoal, sulfur, potassium nitrate).
- Lead became the preferred projectile material due to its ballistics properties and ease of casting.
Ammunition Types
- Pinfire: Popular from 1890-1910, limited availability by 1940 in the UK, used calibres included 5, 7, 9, 12, and 15 mm.
- Centre Fire Ammunition: Made from brass with a heavy head and a primer pocket to ignite the propellant.
- Caseless Ammunition: Missing a cartridge case; the primer is located at the rear of the propellant.
- Blank Ammunition: Similar to bulleted ammunition but without a projectile; sealed with crimping or plugs.
- Tear-Gas Cartridges: Contain lachrymatory gases like CN or CS, similar design to blank ammunition.
- Power Tool Cartridges: For tools and vary in caliber, often color-coded to indicate strength.
- Grenade Launcher Cartridges: Designed for discharging grenades; identified by crimped case mouths and specific color coding.
- Dummy Cartridges: No primer or powder; used for training and safe handling of weapons.
- Snap Caps: Used for dry firing to prevent damage to the firing mechanism; usually rubber or plastic in place of the primer.
Priming Systems
- Rimfire Ammunition: Firing pin crushes the hollow rim to ignite the primer.
- Centre Fire Ammunition: Uses a priming cup with an anvil to contain and crush the priming compound.
- Boxer Primer: Self-contained design developed by Colonel Boxer in 1866, utilizes a bent steel disc as anvil.
Cartridge Case Types
- Rimmed: Features a flange for extraction; identified with 'R' in metric measurements.
- Semi-rimmed: Slightly larger flange than the case diameter; identified as 'SR'.
- Rimless: Flange matches the case diameter; lacks a designation system.
- Rebated: Extractor flange is smaller; identified by 'RB'.
- Belted: Raised belt for strength; identified with 'B', used in high-powered cartridges.
Shotgun Ammunition
- Calibres are referred to by bore diameter; above .410, gauge measures the number of lead balls weighing 1 lb.
- A 12-bore shotgun has a barrel diameter of 0.729 inches.
- Shotgun ammunition can contain various missile configurations, from single slugs to ‘dust shot.’
Shotgun Cartridge Components
- Includes over/undershot card, overcharge card, wad column, base wad, shot column, rollover crimp, and felt cushion wads.
