Depends on what the rifle will be used for and who is using it. My personal rifles, benchrest as well my Varmint are loaded to with in .010 and some closer.
You did not mention what kind of dies you are using or bullets. Some bullets have a longer ogive creating an issue with getting them close to the lands. I use Foster Micrometer for my Benchrest 6mm-284 and Redding Micrometer for my .308, .220 Swift and 22-250. The rest are loaded to within .010 and 99% of the time seem to like it over longer.
