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??

In a firearm cartridge, there are a few main pieces. The biggest piece you'll notice is referred to as the casing. On one end of the cartridge is the bullet and at the other is the rim of the casing. Inside that rim, there is a small piece called a "primer." Primers are made of a shock-sensitive explosive compound which is housed in a brass cradle. When the firing pin strikes the primer, it explodes, which ignites the smokeless powder.
