Calculating and Using Drag Variability (EXTREME RELOADING Special Edition)

1 year ago
103

The Drag Coefficient tells us about a bullet's aerodynamics and resistance in flight. We can calculate Drag using data collected by a LabRadar. Drag variability tells us conistent or uniform our bullets are. In this video, we will talk about how to calculate drag using a downloadable spreadsheet we created and how to apply the results.
