Azshooter,
It should probably also be noted that Berger's published BC's changed somewhat after Bryan Litz started working for them. Which doesn't "prove" anything one way or another about published BC's in general.
And the single-number BC's listed on Berger's website can vary from those listed in their loading manual, and from those in Litz's book BALLISTIC PERFORMANCE OF RIFLE BULLETS. The reasons probably vary, and might include ongoing tests, or tweaking of the design of some bullets, which just about all bullet companies do from time to time. Also, the Berger manual is now almost five years old, and a lot can occur in five years.
