Memory is a horrible thing. I think .224" 80 grain SMK's is around .425, the 107 grain 6mm is closer to .520. For specific answers to your question go to sierrabulletsmiths.com

Sierra's base their's on velocity and I don't think it's a G7 for the 80 SMK.

From my research, Litz has a G7 of .217 for the 80 SMK and .262 for the 107, 142= .301, 175 = .243.

Thank you kindly for the info.
