It is possible to use .30-06 basic brass but you'd be better off using the correctly formed 9.3 Sako stuff. I would be willing to bet that brass will be made available once the rifles and ammunition begin to hit the market. However, that doesn't mean it won't be inexpensive. The 9.3 Sako was a proprietary development that was designed by Erkki Kauppi, who was the head of ammunition at Sako for quite a while. Supposedly his goal was a case that allowed for a larger powder capacity than the 9.3x62 but could still fit a standard action and bolt face.
