Gasman,
I got my numbers from the third (2017) edition of Bryan's book BALLISTIC PERFORMANCE OF RIFLE BULLETS.
Interesting - I have that edition of his book, too, but I got the BC numbers from his online ballistic program.
I really wish that Litz would add the BC figures for the new Federal Trophy Bonded Tip and Edge TLR bullets. I think they show real promise as all-around hunting bullets.
