For footage of the GShG-7.62 I would suggest looking through navy footage as the weapon is only operational AFAIK on the Ka-29 troop assault helo.
BTW:
If anyone has any information about the GSh-6-23's pyrotechnic windup system I'd love to see it.
Soviet Gatlings don't have "pyrotechnic" windups... most are powered by gas pressure like an assault rifle. The exception AFAIK is the light AK-306 and 306K guns using the lightened simplified GSh-6-30L. It fires are a rate of 600-1000 rpm and at such a low rate can fire continuously and not overheat.
It doesn't have a cooling system and has an external motor to operate it.
Most other Russian and Soviet gatlings use a compressed air starter and gas power to continue firing.
The pyrotechnic starter is used in most Soviet and Russian autocannons including single and twin barrel weapons and consists of a squib charge that is directed at the side of the shell case... the intention is to blow a small hole in the side of the shell and ignite the propellent when the main primer has failed. In the case of most of the gatling guns the rate of fire is so high that if one or even two or three rounds together fail to fire when the primer is hit or the firing circuit completed (for the electrically fired rounds) the momentum of the barrels will cycle the weapon and a small reduction in rate of fire that probably wouldn't be noticed by the gunner or target would be the result.
In a 2A42 cannon however where the recoil of the round is needed to eject the case and load an new shell a squib is used to fire the failed round and cycle the weapon to clear the weapon and continue firing.
