Bob,No research is time wasted. Like you said, the data will help us understand what is going on in the transonic region. I can't speak for others but I'd definitely like to know. I am going to oversimplify for a bit here: If shooting a projectile at 1000 - 1100 fps has no downrange benefit than from starting at 900 fps then we can save on air in our tanks.Thank you Bob,Taso
