We haven't, but the young fella that leases our place has.......and he loves them. I think that is the only bull he AI's to and he's used him for quite a few years now.
We have first-calf Olie heifers and so far we are very excited. They just became mommas so the jury is out but there is a lot of evidence in other places that he's making good cows.
I only have a few registered sim and simangus cows but my Olie daughter is my favorite and she's bred to Tuition to have a bull calf any day now. Moderate frame, good depth, very good udder. Last year's heifer calf out of her is very nice too.
