Found a big bullet ? in ther roots of a fallen tree

[Deepdiger60]

Iam not sure if this 20mm size round is real or not it does not have any markings no place for the firing pin to hit its filled with something sounds like course sand when you shake it and it had no rust it was found in the roots of a huge tree that was blown down behind my job in the woods durning the nor-easter we just had . Ive seen lots of ammo in my military years but nothing like this .
? Any ideas thanks Jim
