Last year an aggressive beach refurbishment project took place near my house in Southern California. The process includes dredging tons of sand from beneath the waters directly offshore and pumping it back to the beach. In addition to a prehistoric sharks tooth, I found a 20MM round that appears to be UNFIRED. (see pics).

I’m wondering what type of round it is? Clearly the outer jacket has deteriorated leaving the inner “bullet” intact. Any idea what type of round this was?? I was told that the Japanese planes carried these rounds? I’d be interested to hear if anyone as a theory as to “how” it might have ended up in the Pacific ocean off Sunset Beach???

Thanks in advance…
