The only 147 ELDM that I have ever caught, was a deer that was quartering toward me at about 80 yards, or so. It went through both shoulders and was under the skin on the off side. I have shot a lot of deer with them on depredation permits and regular permits and a few antelope. I have gotten along well. One time like what you experienced, will definitely turn you off of a bullet. It is kind of like me with SSTs.1800-2200 fps depending on distance. I haven't shot anything up close with the ELDM bullets to see if they perform like the BT bullet or not at those ranges. I was just expecting to have different results. Maybe my expectations are off. My buddies buck was shot at about 250 yards with the ELDX instead of 600+. I haven't shot anything with a BT out past 300 yards. Never really needed too. I had similar results with the berger bullets on smaller deer too.
