[QUOTE="BergerFan222, post: 1228372, member: 88896"] Someone help me out: do AB's custom drag curves extend far enough down into the the subsonic region to be accurate at two miles for a significant subset of their bullets? Or are subsonic drag curves something they have really only worked out for a handful of bullets for the 2 mile thing? Please correct me if I am wrong, but the AB acoustic method as described in the books would only work with supersonic bullets. Is there some modification or adaptation of the method to get it to work for subsonic bullets? Radar is known not to have any limitation determining drag curves through the sonic transition and down into the subsonic range. Knowing this, I would think it would be much easier for Hornady to provide accurate drag curves for a wide range of bullets at transonic and subsonic speeds. How many bullets does AB really have drag curves for down to M0.8 or M0.6? And how were these determined? [/QUOTE]
