No point in getting opinions when what you need is a fact. Just look them up on the Hornady and Berger web sites.

Edit: OK. Now I see it. They haven't published the BC's yet and haven't added the drag function to their 4 DOF calculator, either. I would just call Hornady and ask when that information will be available.

I looked at scaling the BC's by sectional density differences, but it didn't work for the 30 cal's, so they aren't simply duplicating the nose and tail profiles. Each one has its own shape design. So calling Hornady is about all you can do, short of buying and testing them.
