So I guess the primary question I have is, "Can I effectively use some 'American' components (bullets and barrel) for this chambering?"

The reamer I've acquired is ground to CIP dimensions which, from what I understand, means using a .285" bullet. Would the standard .284" bullets provide adequate accuracy? (This will be a hunting rifle.) If not, who offers a premium grade "European (.285)" 7mm bullet and how would I go about obtaining some?

The additional .001" in bullet diameter gives me pause concerning the barrel as well. Is there a barrel maker out there who offers a European 7mm barrel?

Thanks in advance for any assistance in this matter.
