Generally we don't "guess" when it comes to reloading bro. 0.010" is pretty thin but should hold a bullet. Your necks aren't going to last long though since they will be expanding and contracting so much during firing/sizing now.
With removing that much material more than likely your sizing die will not be able to size the neck down small enough to give good neck tension. As a trial and error step you could try removing your expander ball and see if the necks will then grip a bullet. That way the expander ball isn't opening the neck back up.
