The outfit I work at regularly does stuff at ~.0002" precision, but frankly no projectile is going to give half a crap about that - it's like trying to figure out how much better a lighter kid's see-saw will do at flinging things when there's an elephant at the other end, it's going to be completely lost in that process.
This does have me thinking about how reasonable it would be to start making the .308 uppers though...
