Sig 2400abs question

[FireInTheWire]

Anyone here familiar with this rangefinder? Question I have- I'm running factory Horandy 147g ELD Match in 6.5c. Horndy's site states that round's BC is
G1=.697
G7=.351

But on my Sig app... in the bullet library.. It has that bullet's BC showing to be
G1=.654
G7=.335

Why the discrepancy? Can anyone shed some light? I've done some searching but haven't found the answer. I thought I'd ask here before I call Sig.

I believe that comes with Applied Ballistic software. They probably tested that bullet and came up with their own numbers. I would trust them over Hornady marketing.

I looked it up on the Ballistics AE app on my phone. Just the same Hornady #s. There are some Litz #'s on there sometimes that are actual test data, but not for that bullet - sorry.

Yes sir. I called Sig and that's exactly what they said. Thanks

If I give you my actual FPS for that round out of my gun... Can you tell me what the actual BC would be? What other info do you need? I didn't know if your software would give that...
