Thanks for your observations. I really have wondered about the published numbers myself - they have always seemed high to me also. I do wish I really knew how they were derived.
I have always had a little better feeling for the way Sierra publishes their BC but I do not how accurate they are either.
For some reason, manufacturers of ML bullets seem to do a much worse job in the BC department than for centerfire bullets. For example I can take the MV for my 300WM, then enter the exact BC, and the drop will be spot on. I shot to 860 yards last year and was within 2 inches on drop.
