Thread: Anyone seen this before?

Greetings All,
My standard prep for new brass is to lightly lubricate the inside of the neck with a strip of Chux cloth wrapped around an old bore brush and run the expander button in and out of the case mouth. There is no need to neck size and new cases should definitely not be full length sized unless they won't chamber. A chamfer inside and out completes the process. Cases are full length sized as part of their final forming process and the necks are not expanded so the necks usually are concentric with the case body. Full length resizing unfired cases can do more damage than good.
Regards Grandpamac.
