As the .40 S&W headspaces off of the mouth of the case and uses a taper crimp, I don't see any issue with re-seating them .010 deeper. You did set your crimp to just removing the bell on the case. right? With the load you describe I'm assuming you are using jacketed bullets. Bullet should slide into the case with no damage to the jacket. I doubt that .010" would have any major effect on case pressures either.
