Seriously, guys??? Just shoot one into the air, then catch it in your hand when it comes back down. Sheesh. Easy.

ETA, we had a bullet pass through a steel roof on a hangar and penetrate both the top and bottom skins of a fuel tank of a plane in said hangar. Didn't work out when the next pilot took off with a "known full tank" and came to grief later. (Pre-flight check is like gravity, it's not just a good idea, it's the law!).
It apparently happened on the fourth of July.
