Here is an image of the VS-5 (cyrill.: BC-5) self-destruct nose fuze, used currently by former USSR forces for shooting various caliber "live" ammunition on limited ranges.

Hi Erhard
Does that mean the setting time to destruct is a lot shorter than normal if thats possible?

No Steve,
the SD-mechanism is activated when the projectile is fired. There are 2 primers, which will move back due to setback against 2 needles. The flames of the 2 activated primers ignite a powder train delay compound, which, after burning, will set off the detonator and booster charge of the fuze. There is no time adjustment.
