[QUOTE="BergerFan222, post: 1226588, member: 88896"] Hornady's tech document says their 4 DOF solver is using the modified point mass (MPM) method. The BRL paper in the link explains that the parameters for using the MPM method can, in fact, be determined from radar data. Since BRL has worked out a method for doing it and has been doing it since 1990, I'm not sure why you are saying it is impossible.
