I think the champion foundation sim in MN was an Oreilly Factor. Have hfr to Oreilly Factor in a couple weeks as well. On the flip side I have not seen many sim cattle out of either bull.
Seen a bunch of O'Reillys on Simmental heifers and cows. Simmy breeder talked me into using him and only ended up using on a Hired Man clubby heifer. She laid down a shot him out. Turned out to be good calf. I would use him again.
