I can't speak from personal experience on the ELD-X. I haven't heard many good things about it at ranges closer than 400yds. They tend to fragment with their construction and jacket combination.
As for the ABLR, I use that in both rifles now. The closest I have taken a shot with one on an animal is 300yds, and I couldn't have asked for better performance. The bullet went in .277 and came out over an inch, after blowing through a rib.
The bullet punched through both lungs and clipped the heart. The deer made it about 20yds before it laid down to bleed out.
