That's strange, mine works with it. I have to maneuver it so the handle isn't in the way, but otherwise, it is fine.I really, really like my Co-Ax and I can not imagine a better primer catching system. My only complaint with the Co-Ax is that I can not use my RCBS collet style bullet puller with it. Not that I'm pulling bullets all the many at a time, but...…….. It was a near toss up for me between the MEC and the Co-Ax.
