Has anyone shot the Winchester Supreme Long Range ammo?

Maybe this is the solution for my 30-06. But does it live up to the promises?

Their ballistics calculator claims, at 8,000 feet, that it maintains >1500 ft-lbs of energy to 675yds (not that I would shoot that far).

I got some of it. Early results were looking pretty average for SD around 16. I’m trying it in a few cartridges and rifles before I can opine on accuracy or terminal performance.
