thanks yobuck for bringing me back to reality. What I am trying to do is provide the best most accurate information to Leopold for setting up my CSI cap. The CSI cap replaces the elevation turret cap to be marked in distance, so no dope chart needs to be referenced proving quick adjustments. Now I understand that this type of cap is inherently not precise as it would be set for one velocity, elevation and temperature and will be slightly off if any variable changes. This is for a hunting gun and should get me within minute of kill zone.

Is there a way to calculate a velocity by charge and type of powder, weight of bullet and shape and column of case? Maybe I could see where that falls into possible speed. I just ant to get a good estimate to use with out buying another piece of equipment that I do not see using all that much.
