I was researching some of the projectiles out there and realized just how much has changed in the last couple of decades. The 7mm has achievable coefficiency of .684 with a 180 grain Berger BT.

The 6.5 is in the .640 with the 140 grain. BT. this is only one manufacturer too. I know who I'm going to purchase my bullets from now.

Thanks for the education.
