Here's the deal on Yellowjacket as I see it based on my experience raising and showing them:
He is a darned good bull that throws pretty consistent, darned good calves. But the steer calves will get bigger - not just frame but total mass - than what judges want today. It's real hard to get them to finish under 1400 lbs. However, I have only used him on cows that in hindsight are probably too big.
If he is going to work for steers, it would be on the Heatwave daughters or possibly even better, Monopoly daughters. I think the Monopoly dams might give his steer calves a better chance to finish easier.
Only prospect steer show we've ever won in Texas was with a Yellowjacket. That calf went to Houston weighing just shy of 1500 lbs and still wasn't quite fat enough. However, he was the third calf pulled - at the first glance the judge took at him - in the heavy Maines - ahead of what went on to be the Grand Champion Steer of the show. Once the judge realized just how big he was, he kicked us completely out of the ring to the gate. Not sure how to describe that result.
I've never had a Yellowjacket calf I didn't get sold for a show calf. How many sires can anyone say that about?
There are more than a few people on this site that have placed Yellowjacket steers at majors.
Am I using him anymore? No, but he is a long way from being a bad bull.
My advice: if you are trying to raise show steers and are having no luck or terrible trouble with structure, etc - give him a try.
