This is actually an exact science because these
ignition systems must start an adequate, consistent and common flame front
in the main charge. If , for instance, two or more separate flame fronts
were inadvertently started at the same time, the collision of the
independent flame fronts would cause a very rapid rise in pressure in the
shell, which then sends the main charge from a rapid burn mode to explosion
mode. This is called detonation and the phenomena is exactly the same as in
an automobile engine except much more violent.


In small arms...this is known as a Kaboom.
