John,
Thanks, I believe that was on the Campfire a few years ago. Or I ran into it elsewhere.
But my main points were:
1) Nosler doesn't ALWAYS over-report their bullet's BC's. It's hit-and-miss, if you'll pardon the pun. In fact some of the long-time listed BC's for Partitions have found to be just about right-on by Litz's tests, including the .30-caliber 200-grain, one of my old favorites.
2) There's a resource that helps a lot when in-putting data not just for Nosler bullets, but others, and it's BALLISTIC PERFORMANCE OF BULLETS.
