Ballistics and Predictions

Quote:
About a year ago, the Lapua company released aerodynamic data for some of their bullets. However this time the numbers were based on measurements taken by Doppler radar. Itís important to note that no public details were given in regards of the equipment and configuration used to take the measurements and post processing.

Doppler radar is, without a doubt, the most reliable method known to ballisticians to obtain in-flight aerodynamic data. Doppler radars are used to acquire exact real world data on the flight behavior of bullets. From the collected data points, through a process called Data Reduction, Lapua derived Coefficient of Drag curves, from which BC and other important parameters were calculated then referenced to the ICAO Standard Atmosphere, in order of make these numbers useful for post processing in ballistics programs.

    Truly a SHAME! A great article filled with many facts for those that may care about ballistics and most people could not really make out the charts and graphs to really appreciate what was being said.

    I decided to put them together so you, the reader, can have this page open and using a different window have the article opened and by just clicking back and forth appreciate the article by being able to see and read the charts and
    graphs.

    The first challenge was to make them readable, clear and make the file as small as possible... 276 KB will have to do...

    The second challenge was to keep the charts the same size without allowing the photo holding site to shrink the original...

    Eaglet, your welcome. You've done these sort of aids before and I know it takes a fair amount of your time and makes it easier and/or more convienent for us folks and didn't want your time and talent to go unrecognized. Take care.
