Quiz 2 - Ballistics
Types of Bullets Viewed in Lab
-1) Full Metal Jacket
-This was designed to go through things, ex. a body. The full metal
exterior keeps it together and stops it from deforming or
mushrooming upon impact
-2) Lead Round Nose
-This will deform on impact and bounce around inside of the wound,
therefore creating more damage
-3) Jacketed Soft Point
-This will mushroom on impact, and will stay within the wound without
going through. The larger the cavity, the more damage caused.
-4) Jacketed Hollow Point
-This is made out of copper, and will bloom out like flower petals once
its in the body, therefore there is more damage done, but this will
prevent it from going through the body. This is what police use
-5) Wadcutter
-This will not go through an object, it will just cause a wound. This is
used for target practice, since it will leave a nice round hole on
targets, which will be easy to analyze
-6) Semi-Wadcutter
-This is similar to a wadcutter, but it will cause more damage due to
the ridges.
-7) Boat Tail
-This is very high velocity, due to its shape, and can go long distances
while being stable, due to its boat tail.
Background
-Handguns (revolvers, semi automatic pistols), shotguns, rifles
-The cartridge contains a powder charge (black powder), a projectile (bullet), a primer
cap that will be struck by the firing pin and a case to hold all the components
together.
-Pistols, revolvers, and rifles have rifled barrels which will twist the projectile as it
travels down it, which allows the bullet to travel further in a straight line, and will leave
rifling marks on the bullet
-Shotguns and some rifles do not have this twist and travel down their barrel smoothly,
therefore they have shorter flight paths and won’t go as far in a straight line.
-In a revolver, the cylinder will rotate due to the trigger being pulled which will cock the
hammer, this will place the cartridge in line with the firing pin and place it in the firing
chamber to guide the bullet in its path of travel. When the trigger is fully squeezed, it
will cause the firing pin to hit the primer and ignite the bullet, which will cause it to
travel down the barrel and exit the gun

Document Summary
This was designed to go through things, ex. a body. The full metal exterior keeps it together and stops it from deforming or mushrooming upon impact. This will deform on impact and bounce around inside of the wound, therefore creating more damage. This will mushroom on impact, and will stay within the wound without going through. The larger the cavity, the more damage caused. This is made out of copper, and will bloom out like ower petals once its in the body, therefore there is more damage done, but this will prevent it from going through the body. This will not go through an object, it will just cause a wound. This is used for target practice, since it will leave a nice round hole on targets, which will be easy to analyze.
