If that was directed at me:
I used him on two females, one a Meyer 734 %simmy and a My Turn female. Had a heifer out of the Meyer and a steer out of the My Turn. The heifer seemed too straight for me after weaning so she went to the sale barn. None of her other calves have ever had a problem, but I get it in the clubby deal sometimes certain matings just don't match up. The steer ended up 2nd in his class at state fair, just a powerful/muscular steer. Very small sample size but I gave my honest opinion from what I have experienced. By no means did I mean he wasn't a good bull, I think Jesse James is a solid calving ease option (both my calves came small and alive); we used him again this spring on some heifers that needed power.
Edit: Remembered I also sold a Bojo bred that was bred to him. She had a nice heifer calf, but she was definitely built like a market heifer.
Don't mix up "terminal" with "problems structurally".
