This is still in my mind to this day, so I wanted to find out how to report it, which led me here. Shape similar X-47B drone, although device would just hover with no sound like stationary in the air and was flat black like a stealth bomber.We were in fear after shortley, and trained a scoped winchester sportsman .30-06 deer rifle on the object, and fired 3 succesive shots center mass at the object, with no obvious effect, or ricochet sound. Man with me fired two slugs from a mossberg 12 gauge shotgun center mass, also with no effect.We started to take off running through the woods, and the object pivoted direction and seem to float/hover north. I don not know where it went after, and never saw it again.
