Does anyone know the BC on a 500 Postell bullet in 45-70?
Thanks

By coincidence, I was just reading Dr. Richard Gunn's article on BP bullet ballistic coefficients in the 2007, Edition 1, issue of C. Sharps' "The American Sharps Shooter"; he ran tests with multiple chronographs and got BC = .43 for the current 529-gr. Lyman Postell bullet in the trans-sonic region.
