A friend in Finland did it. There are three different wind speed tracks if you look at the windage knob. My wife and my father can calculate the drag models for a regressive projectile being affected by gravity, wind resistance, and aerodynamic BC, but I can't yet.
My dad's wireless keyboard went tits up on him earlier this year, so he started crunching numbers on his old note pad. He figured calculating the orbital trajectory of the moon would be nice. I said he should take the keyboard from another computer and plug it into his, but that was too much of a task in the real world for him I guess. After a while, he figured the moon's orbit was somewhere over 800m/s, and we concluded that if the moon was perfectly spherical, you could shoot yourself in the back with a .270 Winchester.
He went off to another room, and I wondered if he had over-looked something, so I checked the batteries in the wireless keyboard...he had inserted them backwards! I gave him a real hard time after that one.
"Hey Einstein! You put the batteries in backwards!"
"No I didn't...did I?"
