Also don't forget to brush the inside of the necks before sizing. I also take the the whole mandrel out every so often and chuck it in a drill and polish the button with fine steel wool.

Just an thought. Should we use caution here? I noticed my neck tension getting tighter after doing that a few times. I had taken .003 off of the button and then my brass was not getting expanded enough. What I have done is hone the inside neck diameter of the die and made it where the brass was not getting "over" sized. Cleaning then necks also can cause galvanic reaction. Another no no for accuracy.

Get a Wilson case gauge or check it in the gun chamber before loading, ie after sizing.

Ive had trouble w/ the expander stretching the neck, on the way out, due to lack of/insufficient lube.
