Hey I am tossing the question out again, about a boutique bp mfgr to compete directly for the US market against Swiss BP. At the base of the case is an impact-sensitive primer.

At this point, the firing pin travels forward igniting the primer which in turn ignites the powder, which burns creating gases that build up to create enough pressure to expel the bullet, end of story. By the way, ringing is a cumulative effect and many shots are normally required before a ring becomes apparent. How much or if it actually moves the case depends on many things such as the diameter and speed of the firing pin, hardness of the primer, weight of the loaded case, and whether it is already touching something that will prevent its forward travel such as the bullet being engraved into the rifling, ect.
