Paul, I would guess the middle two bulls are out of 41X?
The middle two pictures are actually of the same bull. He is out of Ace's 1400 bull and his granddaddy was the biggest and best 14Z grandson we got out of our New Mexico bull. The top and bottom bulls are out of Lilybrook cows and my 0827 x linebred Duracell herd bull.
Yes, the top end of the bulls sell October 6th at Cal Poly in the beautiful central coast of California. Morro bay is just down the road from the bull test and Hearst castle is just an hour up the Pacific Coast Highway.
