Mastermind is the kind to make females. He has enough play on just how he's bred on paper that you should like but when you see him in real life, you will soon realize that he is carrying on the Boots legacy. He's top of the pen kind. He's big legged, powerful made, good structured, and flat out nice. Great cattle make great cattle.

DAM. JSUL MARY'S PROUD 2191K
JBSF PROUD MARY
Power on the hoof from the ground up and power in the pedigree generations deep. He has all the look and consistency built into his genes. Perhaps our favorite mating on the great Proud Mary was Lover Boy, we saw those females, good footed, good uddered, and the perfect size, with the volume and the mass that make easy doing, long lasting cattle. Big solid feet, built right, big bodied, solid from head to tail, and the power, masculinity, and look that takes a program forward, easy said he is the Right Choice.
