So you found the bullet, that means it did pierce the hood, right? I don't think a falling bullet could do that, especially not one that small. It looks like a 9mm, maybe a 40cal. Somebody was trying to bussa cap. Close range would explain the single "pop" you heard and a handgun would explain how they missed you at such close range. I'd stay away from there in the future if i were you...
Are you going to present the slug to the local constabulary for analysis?
