Only got to pull the trigger once this year using the eld-x on a cow elk, look like the bullet penciled in nice and expanded hard as it did not exit the far side. Severely hemoragged the far side under the skin. Shot was broadside at 440 with a 162 from 280AI. Did not gut the elk just deboned gutless method, so didnt see the internal damage but after hit lurched forward and stayed up for 10 seconds and tipped over.
