Range Report Hornady BC data for .308 178gr ELD-X, ELD-M, Match

[solst_ice]

The BC data provided by Hornady is not consistent at all:

BC data taken from the Hornady website:

Match:
G1: .530

ELD-M:
G1: .547
G7: .275

ELD-X:
G1: 535
G7: .271


The ELD-M got the highest BC, followed by the ELD-X and Match.


BC data according their paper product catalogue:

Match:
G1: .530
G7: .268

ELD-M:
G1: .515
G7: .259

ELD-X:
G1: 545
G7: .275


ELD-M got the lowest BC there.

When I use Hornady's 4DOF calculator, the ELD-M also seems the have the lowest BC there.
I found a website where Bryan Litz published the measured data for the Match bullet:

http://www.longrangehunting.com/threads/hornady-178-bthp.92591/

It's 5% lower than the advertised values.

Is there anyone who knows measured G7 BC's of the Hornady .308 178gr ELD-X, ELD-M bullets?

Any experience how the perform compared to the 175 gr SMK and TMK?



Thanks in advance.

solst_ice, if it were me I'd call Hornady customer/tech support and put the ball back on their court. After all, they are the ones with all the fancy resources and have most to gain by sorting out the inconsistencies and providing you with a definitive answer. Good luck!
