Is this a bullet hole?

I say bullet hole.

Reminds me of an e30 M3 owner who was complaining that his fuel tank doesn't hold as much as it should. It was roughly 4-6 quarts short of what it should be.
Turns out that the previous owners used it for smuggling drugs into and out of Mexico, so they had a shop make a compartment below the back seat with a door into this compartment.

I don’t think it’s a bullet hole, usually the metal on other side is torn and doesn’t look so clean. I really have no idea what that could be lol.

Was doing some detailing the other day and came across a piece of electrical tape in the door jamb. Peeled it off and found this.....



Looks like a bullet hole to me. However, I didn't find anything in the body panel.





Its in quite a peculiar place. Hard to think it could be from anything else. What do you guys think?
