First, thanks for your refreshingly frank and accurate comments about these cartridges. I appreciate those who know what they have, and are honest about it.

Without looking it up, my expectation would be that the this could be quite close. The velocity of the 7mm will be higher and the trajectory will be better. The BC is a toss up and will depend on the specific bullet used. That will be the determining factor on which has more down range energy. So energy a toss up and flatter goes to the 7mm. If you load the 300 to give the same flat trajectory you will pay in recoil.
