Percussion bullet

Percussion or Explosive Bullet. A bullet provided with a percussion cap which, on impact, explds a powder charge inside the bullet... 

Pyrodex comes in several types RS for rifles and shotguns, P for handguns, C for BlkPdr cannon, and CR for BlkPdr centerfire cartridges. It requires very firm bullet-seating, hot percussion caps, and a strong hammer-spring for... 

The larger rifles such as the familiar military rifle use cartridges of the type shown in Fig. 19.3. The relatively heavy base contains centrally a pyrotechnic percussion igniter (cap) and also a rim on which the ejector mechanism operates. Bullets can be made of various materials, but the detailed construction depends on whether they are to be used for armour piercing, anti-personnel, incendiary or tracer purposes. In operation, the primer is fired by the striking pin of the rifle, the propellant ignites and the...

Desensitization or phlegmatizotion) of an explosive, means rendering it insensitive or less sensitive to the following actions heat, shock, impact, percussion, rifle bullet or friction Desensitizer (or pblegmatizer) is a substance which makes insensitive or reduces the sensitivity of an explosive. The term phlegmatizer is also used for a material added to a cannon propint to reduce its erosive effect in gun barrels Desensitized explosives are those which are made insensitive to the above listed actions. 

Exploding bullets are not a recent concept. About the middle of the nineteenth century two types of exploding rifle bullets were invented, one using a percussion cap and black powder and the other using mercury fulminate. Figure 11.5 illustrates both types. 

One definition of a blank cartridge is a percussion initiated cartridge that does not have a bullet or missile that is designed to be lethal. However, blank cartridges are dangerous if misused and serious injuries and a few fatalities have resulted from their misuse at close range. (A dummy round is not a blank as it is completely inert.)... 

HGNTA forms heavy, granular crystals, which are not very soluble in water—the crystals are stable in nitric acid. HGNTA detonates when heated to 215 Celsius. Its percussion sensitivity is similar to mercury fulminate, and it s used in primers for bullets and the like. It can also be used in booster compositions in place of, or in combination with lead azide or... 

CHAPTER 17 THE PREPARATION OF NITRO TETRAZOLES LNTA forms heavy, granular, yellowish white crystals, which are not very soluble in water—the crystals are more readily soluble in hot water. LNTA detonates when heated to 220 Celsius, and is slightly more percussion sensitive then mercury fulminate as a result, its use in priming compositions has been questioned, but it can be safely desensitized by mixing with dextrose, flour, or gum Arabic immediately after preparation. The desensitized product can be successfully used in priming compositions for use in bullet primers and the like. ... 

Ammonium picrate forms bright yellow scales, or orthorhombic crystals, which are insoluble in water. The crystals explode easily from heat, shock, friction, fire, and percussion. Ammonium picrate is commonly used in priming compositions for bullets and the like, initiation compositions for blasting caps and detonators, high performance rocket propellants, and fireworks and other pyrotechnic compositions. Ammonium picrate should be stored submerged in kerosene. ...
