Please ignore the MV on the electronic target. You are wasting your time thinking this is accurate. It is a mathematical calc using an extremely short distance (couple of inches on the microphone stalk), and does not account for the entry angle of the trajectory.

Looking at the Litz / Applied Ballistics book, your 162gr SST has the following BC:

G1 : 0.535
G7 : 0.274

I also see that your zero atmospherics and those for when you are shooting are the same. Did you record actual atmospherics when you zeroed ?

100m zero you don't need to put your zeroing atmospheres in.
I would suggest that is another brand of scope that doesn't dial correctly.
Tall target test will confirm this.
Some thing not right anyway.
Bullshit in bullshit out
