I have been reloading for awhile and understand the concept of partial resizing but don't completely understand how to adjust my dies to accomplish it. I am resizing my .338-06 brass with a set of lee dies and they don't offer a neck sizing die without custom making one and I'm try to just bump the shoulders back on my fired brass .001-.002 or if I can just size the neck? So can someone please help. Thanks Kris
