270 not liking ELD-X. What should I try?
I haven't had any luck getting my .270 Win to shoot the ELD-Xs well, in spite of hearing good things about them from a number of sources. Best accuracy was a 40mm group at 235m but that was at the starting load, and the groups opened up to 100mm and I hit pressure signs before getting to decent velocity.
After re-checking the max. seating depth, I figured I could reduce the jump by a fair bit. It didn't help accuracy, and if anything made the pressure worse.
Rifle is a Remington 700 SPS, 24" suppressed barrel. I'm using AR2213SC powder.
130 gr Berger VLDs went okay, but were also getting pressure signs at useful velocities (I'm looking to develop a 300m+ hunting load, so a light projectile would need to be humming). The 140 grain SSTs seem to give me a serviceable mix of accuracy & speed (2950fps, 70mm groups at 235m) but I really hoped the higher BC of the ELD-Xs would deliver better.
I'm wondering if I should try a slower-burning powder, play around with the seating depth some more or give up and try another projectile. I was also going up in 1 grain increments, so could try smaller increments in case there's a node somewhere in between.
Cheers guys - I'm still pretty new at this, so please excuse any rookie misunderstandings.

First step will be to try in smaller increments as you are correct that 1 grain increments are too big and you have probably missed the node.
Try .5 at a time and fine tune further in .1 after you are close to the node.
And don’t get too caught up on speeds as even those starting loads will kill cleanly out to around 500m as long as the accuracy is there.
