Have not had that problem before with several other bulls I have ran through with most around a ton at the time. This bull has a large neck probably bigger than his head. I don't believe any would hold him. (kind of like a hog head, neck as big as their head) After he runs after a few cows he will get in his work clothes. I like my Priefert as I set the auto feature and out of several hundred I have ran through it will snag 98-99% with me, myself and I working them. I had one cow with horns I had to open wide as she was quick to jump through that I had to circle around again to snag. It works awful good IMO. I had a saloon door style I used on a few head and it went to auction.
