The 2nd gun fires at the same speed relative to its self regardless of the speed it is moving relative to the earth so I figured why not add the speed of another gun and get much more energy? To my knowledge no one has ever tried shooting a gun from a gun before. Perhaps using this method I could overcome the limits of gas guns and actually launch something into space. This was just a proof of concept test, perhaps next week I will shoot at something or start building bigger. Everything is home
