Rolling them on a mirror, one should be able to spot any runout over .005"-.007". Most guns shoot fine with .005" or less.
Overbore calibers with long throats like weatherby's and RUM's don't like any runout over .003" I find. The closer you are able to load to teh lands the less runout is an issue. I don't know this for fact, just what I see from my experiements.
