Anyone know the G7 BC for a Lapua 123 Scenar?

[DJ111]

Just wonduring if anyone knows the true BC of the Lapua 123 scenar or the G7 BC?

Is the G1 BC of .547 true?

Thanks,
Dallas

Still a mystery to me after various testing.
The actual drops out to 600yds suggest a G1 of at least 0.6, well that's using the JBM engine in my iPhone's Ballistic app.
A G7 close to 0.3 actually fits better.

I'd be very interested to know what others have found

ChrisNZ, when you say actual drop at 600, are you talking how high it is at 100 after being zeroed at 600, or just how many clicks from 100 to 600 you observed?

 

[ChrisNZ]

No, I'm talking actual impact at 200 (=zero), 400 and 600

cheers
