G1 Megatron

Well I finally scored my first ever G1 megatron. Its the japanese book style #6 version. And the best part --- Cha ching only $50.00 USD. I am probably never gonna open him, unless I get another. He is one badass looking MOFO. But I have a question (bear with me Inever had a megatron before). What are the 20 somethin bullets for? Does Megs actually fire plastic bullets?
