Let’s get started…
Ballistics, Cartridge, & Ammunition Components P1: Case
Called a cartridge, not bullet.
Again, The whole thing, bullet, case, powder and all is called a cartridge.
The biggest part of the cartridge is the case.
It is the big brass hollow thing that holds your charge.
Part of the Case that resembles a bottle neck is called the neck.
The brass ring at bottom flat part of the case is the rim.
Small metal circle in the center of the rim is called the primer.
Most Ammunition is center-fired. Here are some rim-fired cartridges:
Rimfire ammunition, from left to right, .22 Short, .22 Long Rifle, .22 WMR, .17 HM2, .17 HMR
The indention around the bottom of the case above the rim is called the cup.
This is commonly used by auto and semi-autos to eject the case after firing.
Inside the case is housed the powder charge.
Ammunition Powders for Reloading
The bullet is the shiny copper part that is located inside the neck of the case. It has lead inside it.
Bullets can be many shapes:
Lead is used in a bullet core because it is cheaper to cast and is heavy.
Penetration of a bullet is affected by many different factors.
Great for defense or hunting.
Similar manufacturing process as OTM
Exaggerated opening at front of the bullet
HP opens upon impact causing larger shock wave and wound
Think of a HP filled in with lead and protruding a little.
SP has better ballistic properties than HP
The flattening of the bullet isn’t as dramatic as HP.
Use a Ballistic Tip for FMJ accuracy and HP benefits at the same time.
It is a small piece of plastic stuck in the tip of the bullet.
