Yeah, ELDX really make me nervous. I know someone that killed a bull elk with a 143 gr 6.5 Creedmoor ELDX. Yes, it died, took two shots, no blood, no sign of a hit, bull started to walk off and the just fell over. The bullets were found on the far side and they literally did not expand; they looked like bullets ready to be loaded. Thank God it was right in the heart because it would not have killed that bull otherwise, in my opinion.
