Hello guys, I recently dug up a few bullets in a nearby forrest (Belgium) and i wonder what you guys make of these. I think the left one is a .303 but i am not sure, there are no visible markings on it. The others ones seem to be a clip of 7,92x57. Markings on the back are 16 S67 GM 8. Does anyone know where they are from and when they where made?
