What is the difference between gunpowder and explosive?
Gunpowder is classified as a low explosive because of its relatively slow decomposition rate and consequently low brisance. Low explosives deflagrate (i.e., burn at subsonic speeds), whereas high explosives detonate producing a supersonic shockwave.
What was cordite used for?
Cordite was used for large weapons, such as tank guns, artillery and naval guns. It was also used in the . 303 British, Mark I and II, standard rifle cartridge between 1891 and 1915; however shortages of cordite in World War I led to US-developed smokeless powders being imported into the UK for use in rifle cartridges.
What is the propellant in modern bullets?
Modern ammunition uses a smokeless gun powder as the propellant. Traditional gun powder is a mixture of charcoal, sulfur, and potassium nitrate. However, smokeless powder uses nitrocellulose as the main ingredient.
What is similar to gunpowder?
Cordite is a family of smokeless propellants developed and produced in the United Kingdom since 1889 to replace gunpowder as a military propellant. Like gunpowder, cordite is classified as a low explosive because of its slow burning rates and consequently low brisance.
Which definition describes explosive material?
An explosive substance is a solid or liquid substance (or mixture of substances) which is in itself capable by chemical reaction of producing gas at such a temperature and pressure and at such a speed as to cause damage to the surroundings.
What does +P in ammo mean?
Overpressure ammunition
Overpressure ammunition, commonly designated as +P or +P+, is small arms ammunition that has been loaded to produce a higher internal pressure when fired than is standard for ammunition of its caliber (see internal ballistics), but less than the pressures generated by a proof round.
What type of powder is used in bullets?
What is the difference between black powder and blasting powder?
The main difference between Gunpowder and Black powder is that they have their separate uses for people. Gunpowder is used in firearms whereas black powder is used for flares, fireworks because they are very sensitive to flame and spark.
What makes gunpowder different from black powder?
Black powder is coarser and is not as pure as gunpowder. It produces a spark when ignited, has a distinct odor, and leaves soot on the barrel. Gunpowder is made with other ingredients that make it finer, purer, and smokeless which is necessary in firearms because smoke can be a disadvantage to soldiers during combat.
