Seating depth of Hornady's new ELD-X bullet

[Iron Worker]

7mm WSM 162gr ELD-X How far away from rifling ? I recall A-Max bullets like being seated into the lands. Sierra 160 gr TMK I seat .020 away from lands. The Hornady bullets will be my deer bullet .

I just did a load for the 143 eldx. Started at 10 off. Then 20-40-60-80-120 in 3 shot groups same powder charge. 60 shot best. 1/2" at 100. Tried 55-60-65. All 1/2" or less. 65 was .3.

What powder shot best for you?

 

[Rhovee]

I used RL 26. Fed 210 primer. Mine was a 6.5 wsm. H1000 and H4831sc would be two other good ones.

I use the 212 eldx out of my 300 win mag and my rifle didn't seem to care about seating depth. Jammed or a little ways off they seemed to shoot the same.

If I may ask what velocity were you getting and what was your COAL?

 

[Rhovee]

In my 6.5 wsm.
RL 26 60 grains
Norma .270 wsm necked down
Fed 210
143- eldx seated .065 off
3060
10 shot es was 9

I could run it hotter but this is very accurate and the brass is hardly getting worked. I could neck size if wanted to. I shot a 2" group at 425 a few weeks ago. I am tempted to try and go hotter. But not sure if it's worth it.

@ OP I seat mine .013" off in my 7RM. I have read though, that the Berger seating test process works well to get you close.

In my 300 win Mag the 200g ELD-X's like .1" of jump. The C.O.A.L is 3.55"

In my 300 Win Mag the 200 gr Eld-X liked 0.010" jump.

I am working up some 178's for 30-06 and asked Hornady about their very deep seating depth. The reply I got said these bullets seem to prefer 10-30 thousandths off the lands. 3.220 is the book spec but I stopped at 3.250 because I was at about 0.180" of the lands at that point. Shoot all over. Got some test loads ready at 30-50 thousandths from lands. Hoping for better results.

These bullets can be a bit finicky with seating depth. I load them in 3 different calibers. Some like jump, others not so much. What I found that worked best was using the Berger Seating Depth protocol. Then you can work up the load from there with confidence

The 212 shoots best at .095" off in my 300 RUM.
