Before I broke down and went with the blue box, I did as biged said. I purchased large lots of LC 7.62, I Cleaned, uniformed the primer pocket, trimmed and chamfered, deburred flash hole and weight sorted. I found that the LC brass compares very well to Lapua after the work. I cant remember but I even compared the brass metallurgy and I'm thinking both fell within C28000 specs but cant remember. Might have been C26000.

I have not seen the consistency in other NATO stuff personally. YMMV.
