Newbie here, but not to reloading. .003 smaller then the loaded round dia. is what you want. Also, when you only neck size the brass, you can reload them many times. Now when you neck size only the brass, you have to use them in the same rifle. When I started shooting competitively back in the mid 80's, Wilson hand dies were recommended to me as the best, and that's what I have using ever since.
