We've killed quite a few animals with both, from antelope at 150 to elk at 890 and they both work, but after hunting with the eldx, the bergers are just target bullets for me.
Why? The eldx is a more consistent killer. I have not seen a failure yet, I cannot say the same for bergers. We've had problems at both close and long range with them. They shoot great, but seem to be pretty random when it comes to terminal performance. Sometimes they work great, sometimes they don't.
Don't get me wrong, if the eldx hadn't come along I'd probably still be using them, but I'd be trimming the meplat to try to get more consistent results.
That's just what I've seen, it doesn't make it fact by any means.
