7.65 Spotter/Reglaje Incendiary Composition

Coming from a chemical background,
I’ve been interested in the initiation of the spotter rounds. While the Russian PZ and German B-Patrone rounds use a dedicated primer (and those primer compositions being available online), I haven’t been able to find much in the way of the 8x56r and 7.65x53, using the same Dordecht inertial primer striker but with homogenous smoke/incendiary composition without initiator- examples of which can be seen in Wolfgangcross’s excellent cutaways. In the attached pictures, including the microscope shot, it appears to be a thermite composition but with a possible chlorate energetic. Just interested if anyone has further information to add to the differences seen in the spotter compositions from various countries.
