And if you're in a vacuum, I guess it's not the weather, is it? :D
Any shot over about 500 meters needs to compensate for this because there is no such thing as 'perfect weather conditions' There is always barometric pressure, humidity, and wind speed.
What if it was like in Firefly when Jayne shot Vera out of the spacesuit?
What if it was like Zoids and they shot Blade Liger out of a railgun?
