Can someone tell me the true BC of a 168vld from a 7 stw going 3200 fps at 7000 feet 50 degree weather?

Anyone could guess at 'true BC' without all the measurements, or local pressure, & humidity..

My guess for local BC:
G1 .827
G7 .399

I don't know if I'd pass a lie detector test though...

sight in your rifle at 300 yards, on a large target shoot it at 400,500,and 600 yards, measure your actual drops. then adjust the BC on your drop chart program till the chart matches your actual drops and there ya have it.

Go to JBM and find the bullet and use the BC from the one that says "Litz".

It is the best of the online ballistics programs.
