Just picked up Quickload and was playing around with the Quicktarget program that comes with it and was trying to see if I could find an answer for you. Quicktarget has a conversion table to convert between the different drag models. The 168 CC bullet carries a .460-.469 G1 BC...so if I did it right it should be a .226 G7 BC.
Maybe someone can jump in and confirm what I came up with.
