Can anyone give me the Litz BC on the 6.5mm 143gr ELD X and the 30 cal 200gr. ELDX.
My second edition of Applied Ballistics doesn't have the ELD X bullets listed.
Thanks guys

In the meantime, from Hornady 11th ed ...

143 ELD-X = G1 .625, G7 .315
30 ELD-X = G1 .626, G7 .315

That is strange. Has anyone verified the difference on the BC?
My information came from the book ballistic performance of rifle bullets third edition copyrighted in 2017 when was the last Applied ballistic update it may be more recent

The 143 ELDX changed significantly at some point. I swapped for an older box from a member here, but also had a sample pack from SubMoa (presumably newer ones). The bullet OAL was ~0.015" different, and neither was the same as what is shown above.

Older box = 1.445"
Sub MOA pack = 1.427"
Posted above = 1.382"

I know Hornady has changed bullets in their lineup before, and revised B.C.s here and there, but this seems a bit strange that there's at least 3 flavors, with 60 thousandths length difference...

FWIW, I calculated the G1/G7 B.C. for the 143X, using my LabRadar, and came out with an average G1 of 0.640 ± 0.01 and G7 of 0.313 ± 0.005. That's out of a 24", 1:8 twist, 5R in 264 Win Mag. Tracking files from 0-150 yds, so velocity range of ~3050 - 2850 fps give or take.

Idk how accurate the projected velocity is from the labradar, they're figured off algorithm, not by the actual radar. I love my labradar and shoot with it all the time, but I don't put much weight in their down range velocities.

I shot my 6.5x47 with 143 eldx out to 900 yards yesterday. I use the BC on the box at .313 G7 and it was money from 200 to 900 yards. Same for my 212 eldx in the 30-28 nosler. What's printed on the box has been money. Hornady is pretty honest. Unlike some others.
