Is it dangerous if the bare wires touch each other?

Hello! Please help, thanks in advance. I have a chain of 20 rounds, a wire fits each cartridge, I cut it in half, connected the cores (blue with blue, brown with brown) and inserted it into the cartridge. After that, it turned out that all these 4 wires (bare) touch each other, please tell me, is it dangerous, or does it not matter? Thank you very much for your reply.
