I bought a new Sako AI single shot 6mm PPC USA HB back in 1991. Always used Sako 6mm PPC USA brass in it. The chamber dimensions were such that there was about .004 clearance on a loaded round using that brass. No need to neck turn. My friend had the same rifle and his chamber dimensions were identical to mine. Don't whether the Sako brass is still available, but it was very good.

Exceptionally accurate for a production rifle. The Sako factory ammunition was loaded with Vihtavuori N130 powder and Sierra 70gr Match bullets.
