Litz himself said the Dopper Radar method is accurate and when Hornady tested Berger bullets through the radar they found nearly the same results as Litz did himself. A 3rd party definitely helps, but you didn't hear me saying Hornady needs to shoot the Berger 195 through Dopler radar to "prove" them. No I trust Berger and their methods for determining BC. Not sure why anyone should question Hornady when they are using the most technologically advanced method of measuring bullet drag and ballistics.
