I have a set of Lee dies coming and would like to do some reloading. I have about 100 rounds of NIB ammo I've collected recently at gun shows or off the shelf when I see it. Any suggestions as to what I can expect while reloading would be greatly appreciated.  :)

The Lee set does not come with a neck sizer. They(Lee)don't make a neck sizer for the 30-40 as a stock item. I assume they will custom make a die to your specs but you can get a bushing neck sizer die from HC-4D   (You need to Login

Though as others have said, I get good results just backing the full length die off a bit.
