Has anyone been doing long range load testing with the 7mm JLK 168 (.690 B.C.) and 180 (.735 B.C.) grain bullets to verify if the listed B.C.'s are even close to what is advertised?

They are optimistic. They shoot very well, no question, but in all my f-class practice, I see them impacting no higher than a Berger, given the same muzzle velocity.

What is the farthest distance that you have compared the 180 Berger's and the JLK's?

Thanks for the info guys. I will have to check out Brian Litz's book. Looks like some good ballistics info.
