Well, like I said it appears to be approximately 45 degrees. There is a general area where I think something might be. But if it is a rock like object I may never be able to differentiate it from all of the other rocks I have in my driveway.
Impacts come when you least expect them. In 1973, a carport roof in San Juan Capistrano, California, took a hit from an asteroid fragment. Owner George Stinchcomb reported hearing a sound like a gunshot in the middle of the night. The next morning, he found an egg-size meteorite that crashed through the carport roof onto the concrete floor.

I'll give that a try but I don't have big magnets so it will only cover a small area at a time.
I am certain of a general smallish area that it has to be. But rocks/and weed eating that I didn't do doesn't help. I'd think I'd see a hole or divot in the ground....nothing though that stands out.

a simple question for everyone saying projectile from a firearm :
what caliber ?
its not a trick question - the threadstarter reports the hole = 40mm * 22mm
in sheet-stock
yes - i am aware of the terminal velocity of projectiles
i want to know - how a firearms projectile - that is not IMMEDIATLY obvious against gravel - made a hole as cited
