Need help with BC of some Sierra bullets

I'm needing to know the G7 BC of the Sierra 224 80 grn MK and also the 6mm 107 MK the 142 6.5 MK and the 308 175 Mk

Thanks in advance.

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.
