I did a little work with the 143 ELD-x. Using Retumbo in my 24' barrel(6.5x284), accuracy, velocity and ES were very close between the two. I have been hesitant to try the ELD-x on game yet given some mixed reviews, and, my rather long exoerience with the 140 Berger's and JLK's which have both performed well on game for me from 200-1000+ yards. As a side note, it appears Berger may be shipping the 140HVLD's. I just received a back-order of 500CT from Midway.
Some 200 yard info. POI very close between the two bullets:
