Smokeless powder is a type of propellant used in firearms and artillery that produces less smoke and less fouling when fired compared to black powder. Because of their similar use, both the original black powder formulation and the smokeless propellant which replaced it are commonly described as gunpowder .
Additionally, gun-related crimes are extremely low; in the past 30 years, the year with the highest amount of gun-related deaths was 39 in 2001, and as low as 4 in 2009. [2] Japan as a whole is largely uninterested in firearms: Graduating police officers most often choose judo and kendo over firearms training. The country's culture doesn't have ...
Gunpowder is a low explosive: it does not detonate, but rather deflagrates (burns quickly). This is an advantage in a propellant device, where one does not desire a shock that would shatter the gun and potentially harm the operator; however, it is a drawback when an explosion is desired.
Black powder produces gas at a predictable rate unaffected by pressure, while the gas production rate of smokeless powder increases with increasing pressure. [6] The possibility of runaway pressures caused smokeless powder to destroy many firearms designed for black powder and required much more precise measurement of propellant charges.
A historian explains how the U.S. was able to enact a federal gun control law in 1968, and why such a law would be hard to pass today.
Law enforcement commonly use swabbing, adhesives and vacuums with very fine filters to collect GSR. [2] They commonly swab the web of the non-firing hand to look for gunshot residue if they are suspected to have discharged a firearm themselves or were in close contact with one at the time of discharge.
The Gun Control Act of 1968 (GCA or GCA68) [1] is a U.S. federal law that regulates the firearms industry and firearms ownership. Due to constitutional limitations, the Act is primarily based on regulating interstate commerce in firearms by generally prohibiting interstate firearms transfers except by manufacturers, dealers and importers ...
