There is not an explosive inside of a case. It is a powder that burns rapidly, but does not have the violent tendencies of normal explosives. if you were to pour the powder onto a table and set it on fire, for example, you would be very disappointed with the amount of flash.
I believe you are referring to "cartridge." The cartridge is the entire assembly of the bullet, primer, powder charge, and casing.
A cartridge consists of a casing (shell) with a built-in primer, a propellant (gun powder) and a projectile/bullet. When the trigger on a gun is pulled, it releases the hammer which strikes the high-explosive primer. The tiny explosion ignites the low-explosive propellant. If the low-explosive propellant was made of the same high-explosive stuff as the primer, the gun would blow apart. As the propellant expands inside the casing, the pressure builds to a point where the projectile/bullet can no longer hold on to the casing. The bullet goes the only way that it can which is down the barrel of the gun. As the bullet moves down the barrel, tiny spiral grooves in the barrel cause the bullet to spin like a spiral pass thrown in rugby or America football in order to make the bullet fly true. When you see the flash of sparks come out of the barrel, that is the remnant of the propellant being burnt after the bullet has left the barrel and is on its way to the target.
cartridge
When you shoot a bullet the bullet casing pos out through the ejector and that is where the bullet is and gunpowder to fire it.
hash marks or lines running parallel with the casing, caused by the inside of the barrel of the gun as the bullet travels out when fired
Do you mean a cartridge casing or the actual bullet?? One used in combat or just a WW2 era casing??
Fragmentation
The diameter of the bullet casing, measured at 7.3 mm, is 7.3 millimeters.
To make a bullet pencil, you need a bullet casing (typically a spent cartridge), a pencil lead insert, and a means to secure the lead inside the casing. Start by carefully removing the primer and gunpowder from the bullet casing for safety. Then, insert the pencil lead into the casing, ensuring it's snug, and seal the open end with a cap or a small piece of rubber or cork to hold the lead in place. Finally, sharpen the lead using a pencil sharpener or a knife to create a usable point.
I presume you mean for a bullet? The casing allows the bullet to grip the internal rifling of the barrel without shearing the soft lead of the bullet. The tip helps the bullet expand upon impact allowing all the energy of the moving bullet to be passed on to the thing you have pointed the gun at.
