No experience with ABLR but since you mentioned ELD-X i will give my 2 cents on those.
I have taken or seen moose taken from 25-200 yards with 178 Gr .308 ELDX all neck shots Dropped DRT no bullets recovered.
I have taken a mule deer at 460 yards with 220 GR ELDX .308, heart shot, took 1 step.
Moose at 664 with 220 GR ELDX, through the lungs, bullet recovered on far side hide perfect mushroom, never weighed retained weight, moose tooke one step and rolled.
2 mule does taken at 100 with 143ELDX 6.5 Creedmoor, DRT, one was through both shoulders one was through spine no bullets recovered and devastating wound channels.
I love the ELD-X
