Category 4 Flashcards
How far away is a standard speed 4.5 mm caliber projectile considered dangerous?
100 meters.
Can a projectile fired into water ricochet?
Yes, as long as the trajectory is low.
As long as the fired projectile hits the selected target, can it be considered that the shot is safe? True or false?
False.
What is a ricochet?
A trajectory diverging from the firing line because the projectile is deflected by a surface that didn’t stop it.
Lead projectiles are less likely to cause ricochets than jacketed projectiles. True or false, and why?
True, because lead crushes more easily when it hits a hard surface.
The firing range bed must be covered with sand or topsoil. True or false, and why?
True, because a hard or rocky bed can give rise to ricochets.
Internal ballistics concerns the damage caused by a projectile when it hits a particular target. True or false, and why?
False, because internal ballistics concerns the projectile’s path inside of the barrel.
The columns that support the intermediate bullet stops existing in the shooting range must have a cylindrical shape to avoid ricochets. True or false?
False.
The range of a .22 LR standard velocity projectile is independent of the weapon with which it is fired. True or false, and why?
False. The range depends on the muzzle velocity, which is always greater on a long weapon than on a short one.
What are the conditions for a ricochet to take place?
When shooting into a polished and/or incompressible surface.
External ballistics concerns damage caused by a projectile that hits a particular target. True or false, and why?
False, because external ballistics is the study of the forces that act on projectiles and their corresponding movements during their passage through the atmosphere, from the moment they are freed from the influences of the propellant’s gases up to the presumed hit with the target.
Terminal ballistics concerns damage caused by a projectile that hits a particular target. True or false, and why?
True. Terminal ballistics is the study of the interaction between the various projectile genres and their targets.
