This is a thread for discussion of the article, Ballistics and Predictions, By Gustavo F. Ruiz. Here you can ask questions or make comments about the articleAbout 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. It’s 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.
