I can't buy it either. I will have to make it myself, but the standard for performance will be judged against the factory load. There is very little room for improvement. The great thing about Hornady is that the recipe is not a secret. The load data is out in the open.
It is 46.8 of Varget behind the 168 A-max with a Winchester match primer at 3.315. With the price what it is, it is evident that they aren't just slapping it together. The performance on paper proves it to me.
