2. Primer (firearms) - Wikipedia

   en.wikipedia.org/wiki/Primer_(firearms)

   Various priming mixtures have been used in different sized primers to effect prompt ignition of the powder charge. Particles with relatively high heat capacity are required to promptly ignite smokeless powder deterrent coatings. Some priming explosives decompose into incandescent solids or liquids.

3. Smokeless powder - Wikipedia

   en.wikipedia.org/wiki/Smokeless_powder

   In 1884, Paul Vieille invented a smokeless powder called Poudre B (short for poudre blanche, white powder, as distinguished from black powder) [7]: 289–292 made from 68.2% insoluble nitrocellulose, 29.8% soluble nitrocellulose gelatinized with ether and 2% paraffin. This was adopted for the Lebel rifle chambered in 8×50mmR Lebel.

4. Primacord - Wikipedia

   en.wikipedia.org/wiki/Primacord

   Primacord is initiated with a blasting cap or by a donor line of detonating cord or other high explosive. It detonates along its entire length at a velocity of approximately 23,000 feet (7,000 meters) per second. It is used to create explosive effects and to build reliable explosive charges.

5. Detonating cord - Wikipedia

   en.wikipedia.org/wiki/Detonating_cord

   Detonating cord (also called detonation cord, detacord, detcord, blasting rope, or primer cord) is a thin, flexible plastic tube usually filled with pentaerythritol tetranitrate (PETN, pentrite). With the PETN exploding at a rate of approximately 6,400 m/s (21,000 ft/s), any common length of detonation cord appears to explode instantaneously.

6. Armstrong's mixture - Wikipedia

   en.wikipedia.org/wiki/Armstrong's_mixture

   Armstrong's mixture is a highly shock and friction sensitive [1] explosive. Formulations vary, but one consists of 67% potassium chlorate, 27% red phosphorus, 3% sulfur, and 3% calcium carbonate. [2] [3] It is named for Sir William Armstrong, who invented it sometime prior to 1872 for use in explosive shells. [4] [additional citation(s) needed]

7. Cartridge (firearms) - Wikipedia

   en.wikipedia.org/wiki/Cartridge_(firearms)

   A cartridge, [1] [2] also known as a round, is a type of pre-assembled firearm ammunition packaging a projectile (bullet, shot, or slug), a propellant substance (smokeless powder, black powder substitute, or black powder) and an ignition device within a metallic, paper, or plastic case that is precisely made to fit within the barrel chamber of ...
