We just received Jirl Buck's catalog and it looks like he used Halls Legacy Plus. He might have even owned him. I'd say give him a call. I think Bushy Park Farms has used the bull. I don't think he was been used as much as other bulls out there because the bull didn't have Lautners promoting him but from the looks of the daughters and grand daughters that Buck Cattle are selling, the bull has done a great job. Just my two cents.
