    ? G7 BC for Sig Sauer .270 140 gr Elite Hunter EHT ?? Where to find G7 Data

    Anybody know where to find the G7 BC for this particular factory ammo ? Ridiculous buy Sig does not include the information on their website. When you call and actually talk to a human - they have no clue where to get that information.

    I am clueless about factory ammo, but does this use a 140 gr Berger bullet (kind of sounds like it does)?

    If it is the Berger 140gr bullet:

    270 Caliber 140 Grain Classic Hunter
    G7 BC: 0.271
    G1 BC: 0.528

      Thank you so much for your help.


      That is one of the problems, I think it is a Sierra bullet with what looks like a polymer tip. My guess is that it is a Sierra Gamechanger that they are making for Sig with a different colored tip. I found an article on the innerweb that said Sig was using Sierra bullets - but no confirmation.


      If it is a Sierra Gamechanger then the G1 BC is .508 - but I am not educated enough on reloading or the physics to know what that means in terms of G7 - assuming that is the correct bullet. You would think Sig would know what they are selling - but they do not.

        Well, Sierra doesn't even list a G7 number for that bullet?...….that doesn't make any sense either.

            I don’t trust any published BC data. I shoot groups at 100, 200,300,400. 4 points on a parabola will get you dang close out to 1000 if you and your rifle shoot well.
