The article I linked showed open boxes of Hornady factory ammo next to the rifle. I'm assuming Hornady will be providing factory ammo for this rifle. Hornady bullets definitely aren't Woodleighs, though.

k80,
I have no doubt Ruger will be bringing both the 9.3x74R and 450-400, but I'm not holding my breath for it to be done anytime soon. Ruger does have a habit of loosing the goose before they are ready for production. The Gold Label was probably their most ambitious project yet, and from the time it was announced till it was available was about 2 1/2 years. Hoping we will see the 9.3x74R, 450-400, 358 Winny, 375 Ruger, etc... sometime next year. I don't think we will see them in any numbers before then. 'Course I could be surprised...
