I haven't had the 143 eldx fail at close range in my 18" barreled 6.5prc yet.
One close shot at a sika stag at 20m that was wounded from a failed 123gr sst @2900fps, which I think hit brush before the deer. My final shot was a143eldx @2850fps, this passed clean through a 30mm thick sapling 5m before it hit a raking shot down his ribs then stopping inside the base of the neck/spine.
