Case / Casing
the metal or plastic container that holds all parts of a round of ammunition: primer, powder charge, and bullet
the part of the case mouth that bends inward to grip the bullet; with shotgun shells, the term applies to the closure at the case mouth.
markings found on the head of ammunition that indicate caliber or gauge and identify manufacturer
small, metal cup containing the detonating mixture used to ignite the
propellant or powder charge
the only part not found in any other centerfire cartridge; this is used to seal/confine gases; can be made of plastic or compressed cardboard
complete ammunition cartridge that contains all parts of ammunition; a military term meaning one single cartridge
a measurement used to identify different cartridge (projectile) sizes. It is determined by measuring the diameter of the bore of the firearm
there is a hole in the bullet that creates expansion when a target is struck, creating more damage
a round designed for training or noise; the casing's cardboard material becomes a
projectile when fired; the projectile cannot penetrate
drywall or hollow core doors.
Lead Round Nose
cartridge design that features a solid lead bullet with a round nose; this bullet has a
medium velocity. By design, it easily penetrates interior walls or hollow core doors and then ricochets.
Jacketed Soft Point
one-half to three-quarters of this lead bullet is jacketed with copper; the exposed
lead on the flat nose allows for expansion upon impact. Usually of high velocity, this bullet is designed
for antipersonnel. The round easily penetrates interior walls and solid doors.
lead or copper-jacketed lead with a hollow cavity in the bullet's nose; as the bullet expands
upon impact, it expends its kinetic energy. Since a ___ expands quickly, it does not penetrate
as deeply as a round-nose bullet. This design reduces ricochet. Usually of high velocity, it delivers
maximum shock upon striking a surface of soft tissue.
Full Metal Jacket
a round-nose lead bullet
completely covered with a copper jacket; sometimes called ball
ammunition, it is normally of medium to high velocity. Used extensively
by the military, it has low
expansion and high penetration capabilities. The chance for ricochet is high.
normally made of brass or copper dust held together with a resin material that disintegrates
upon impact with steel or concrete; it can penetrate hollow core doors, drywall, or thin wood material
made of solid carbon or tungsten steel coated with bright green Teflon; it has a
considerably sharper point than most manufactured rounds. The round can pierce protective body
armor or steel. In Florida, its use or possession is illegal for anyone but law enforcement.
full metal-jacketed bullet with incendiary material in the casing of its base; when fired, the round can be visually tracked by the burning material. The bullet tip is normally painted red or orange. Having the same velocity as a full metal-jacketed bullet, it is most often used by the military in fully automatic weapons.
normally used for bird hunting or practice; this shell has a load of small diameter lead or steel shot
pellets. When fired at close range, these pellets can be dangerous and cause injury.
The standard 2 3/4-inch shell contains nine .33 caliber lead pellets. The spread pattern from a 20-inch barrel is
approximately one-inch spread per yard
indentation in the case that may weaken the case wall; a ___ makes a layer of the case wall metal look as if it has been scratched or torn away
dimple or depression in the case; the case looks like someone struck it with a hard object, crushing part of it inward
layering of the case with oxidation or foreign material, such as mold, fungi layers, congealed oil, and lubricants
the recommended time (normally expressed in months) for which you can expect ammunition
to be reliable when used on duty.
