you should only be removing about .oo7" - .01" of the meplat to clean up. Any more than that is unnecassary. No mater how sharp your cutter is you will still get a very small burr in the outside of the bullet that you can catch with your finger nail. There shouldn't be any need to push hard at all. Like others have suggested use 0000 steel wool, one light twist and burrs gone.
