Same experience. I moved a blog on a subdomain onto its own domain with a 301 redirect. Pages started moving over without a flinch.
@Manny123, I went to do a WMT site move But Big-G does not allow the specification of moves from subdomains. Only between base/root domains. So that was a bust. But as mentioned, the 301s seemed to have been enough.
It might theoretically be that the names of the domains involved had an impact?
Maybe big-G do not see the new domain as as good a keyword match to the content, and ranks differently? Just guessing here.
