I neck size only. I have had neck sizer dies made for all of my toys, and I anneal as needed, and will only full length when needed. New cases are trimmed and full power loads are used for forming to chamber.

I keep reading these posts about you guys bumping the shoulder a bit. Now the way I understand a sizing die to work is that it is basically a mould that reforms the brass back to SAAMI specs. So in "bumping the shoulder back a bit" you're not very far from FL sizing. About the only thing you didn't size is the web area of the case which is done by camming the ram against the bottom of the die. Backing a FL die out a bit is not neck sizing - it is partial sizing.
If I'm incorrect I want someone try and explain how they neck size or bump the shoulder in a FL sizing die without resizing 95% of the case.

There ARE neck sizing dies which don't touch the case body at all. These are typically labeled as such - Neck Size dies.

Bronko,i often thought the same way about "Bumping'.
I just could not understand how you could do it?
I have neck sizer only dies.
With these i seldom size the whole neck !

I suppose it's a matter of what equipment you use, and what you decide to call it.
Using a Full Length Sizing die to neck-size, or maybe just bump the shoulder a bit, isn't just neck sizing, even though a lot of guys call it that.
I have a few true neck-sizing dies - ONLY neck-sizers, and I also do often use FL sizers as bump or neck-size dies, which does partially resize. Most of my loading is for AR's, which get a FL resize forever and always. For my hunting rifles, a partial resize & neck size is in order. Only neck-size only, pure neck size only, on bench bolt guns.
