There is some Lapua on EE
You may wish to check with Clayton at PRF (a CGN sponsor)
He had a bunch last time I needed to make up some 6x47.
There is some question about the wisdom of using .223 brass in a .222 Magnum chamber, the Berger Manual says you can, but my SAKO said I shouldn't. Of the 10 factory (American Eagle) I fired, half cracked ahead of the web, and the the resulting neck was too short to hold a bullet anyway. So for me its only .222 Magnum or .204 brass from now on.
The .223 came from the .222 Mag. I'd use them.
You're finding no issues with going up to 6mm from the 204's??
I will look into that...........thanks
