Study Notes

Firearms and Ballistics

The failure of a cartridge to explode due to a lack of firing pin length is known as a "hangfire".
If the priming mixture is active but the gunpowder is defective or wet, it can lead to a misfire or hangfire.
The delay of explosion in a firearm is known as a "hangfire".
Chamber markings with individual characteristics are caused by the unique features of a firearm's chamber.
Breech Face Marks in a firearm are caused by the metal fragments expelled during firing.
The origin of the word "ballistics" comes from the Greek word "ballein", meaning "to throw".
Forensic ballistics refers to the analysis of firearms and ammunition to aid in crime investigation.
The motion that refers to the turning of the bullet inside and outside the barrel is known as "rifling".
The main focus of internal ballistics is the study of the combustion process and the behavior of projectiles within the firearm.
The term "forensic" implies the application of scientific principles to aid in legal investigations.
The primary meaning of the term "forensic" in ballistics is the analysis of evidence related to firearms and ammunition.
The rifling of the barrel is the primary factor that facilitates the turning of the bullet inside and outside the barrel.
The main focus of internal ballistics is the study of the combustion process and the behavior of projectiles within the firearm.
The term "ballistics" originally referred to the study of the trajectory of projectiles.
A "misfire" is a specific defect in a firearm that can cause it to fail to discharge.
A hangfire is considered a delay in the ignition of the propellant charge.
The recoil of a firearm refers to the backward motion of the firearm after firing.
