As far as I can tell, as I don't use the device, the entries with bracketed data are personalised drag models (PDM). The code likely refers to the rifle/person who submitted the PDM.

http://www.appliedballisticsllc.com/Downloads/ABLibrary.pdf

I would simply take the non-personalised version and then modifty that if you need to, this creating your own PDM.

Hornady's own data is an average G1 BC of 0.646 and an average G7 BC of 0.326.

Hi there 

have just been reading the set of books by Bryan litz and very informative they are too . Stability factor might be a better measure of how good a bullet is at transonic distances than bc  . Numbers from his book are for 140 eldm 

g7 bc 0.322 ,+\_ 0.015 .  G1 0.628 +\_ 0.108 . This is for average speeds 3000 to 1500 FPS  . 
hope this helps    Cheers

Yes I know I was just wondering why so many for the 140g eld-m,as most other bullets in the AB library show only one BC in G7 and G1
