Picked up a couple hundred of Hornady 178 ELD Ms and was wondering if the G1 of .547 was accurate ? Like the 178 amax is listed at .495 but Litz has it around .470. Is the ELD bc off like the amax ? Thank you.

It's going to be a little bit different in every barrel. I'd take the manufacturers BC to start with and true it up from there.
It’s a radar derived BC, so it is accurate, but at 2.25 Mach. If you’re shooting a .308, you probably won’t see that number. The intermediate (Mach 2.0) number is .527, and will probably be closer to what you’ll see.

Thanks I’ll start at .527 and true it from there. I’m pushing them at 2740 fps.
All I was able to take it out to was 426 yards. I ran 43.8 varget and Lapua brass with CCI br2 at 2742 fps. I ran the numbers and I came up with a G1 of .530. I know I need to shoot out to at least 800 yards or so to confirm but this program has been pretty dead on so far.
