Wasn't there a chart that listed different loads (hevi13, lead, shot sizes) and listed each at different velocity and gave kinetic energy at different ranges. I cant find it anywhere. Thanks!
This? http://oldgobbler.com/Forum/index.php/topic,553.0.html
Yep, thanks!
Is there any formula to figure out KE at certain distances?

I doubt you would want to shoot your shotgun at a chrono at 40 yards though ;D You will probably need someone with some software to calculate your velocities down range. PM spurosity. He might be able to help you out.
