You might be getting a compressed load with that powder charge because you indicated that you are seating at 2.8010. That is 0.009 shorter than SAMMI recommended OAL.
I find that with the long ELD-X bullets, you should expect that the OAL should be longer than normal recommendations because the tip is so long.
There is about 0.622 inches of bullet tip in front of the ogive, with a bullet body of about .810 inches. That would leave 0.541 inches of bullet in the neck at the stated OAL.
Even if the OAL you listed was a typo and you actually seated at 2.810, you still have a 0.532 length of bullet body back into the cartridge with that very long bullet, compared to an older type bullet with less of a pointy tip. Seat the ELD-X bullet out at least 0.010 longer at 2.820 and see if the compressed load goes away.
I suggest you do the same longer seating with ELD-M bullets also.
A 147 ELD-M has a bullet base to tip of 1.464 with a Base to Ogive of 0.800.
A 143 ELD-X has a bullet base to tip of 1.432 with a Base to Ogive of 0.810
A 140 ELD-M has a bullet base to tip of 1.371 with a Base to Ogive of 0.700.
All have a 0.175 boat tail.
As a comparison with an older design bullet, the 140 gr. SMK has a bullet base to tip length of 1.304 so at a 2.801 OAL there would only be .502 inches in the cartridge to compress the charge.
0.04 inches could be the difference between a compressed load and not having a compressed load.
