Yes, but results may vary depending on the cartridge. I use a fender washer that I have drilled the bore to 7/8" to clear the die threads. Then place it under your FL die and tighten it down. It will size all but the last 1/16" of the neck while the shoulder and body go unsized.

I just unscrew the die until it sizes 1/2 of the neck and adjust the decapping rod down until it just taps the primer out. You need to be a little careful when inserting cases to be sure they are aligned with the die body or have plenty of decapping pins on hand. Neck sizing increases case life and improves accuracy in my rifles.
This works but it is still a partial size because you will lightly size the case walls. You can visually see it without measuring anything if you look at the junction of the body and shoulder. There will be a burnished ring you can see. Nothing wrong with this but if you want a true neck size only you need a neck die. That said you can do a lot by manipulating dies.
This method of backing out the die a bit or putting the washer under it also offers a couple of distinct accuracy advantages for a factory chambered rifle(in the event you are not aware?) #1, by only sizing part of the neck, the remaining unsized portion of the neck will act to center the case in the chamber--------------since it is expanded to about .001" shy of the actual chamber neck dimension. And #2, the base end of the case, being already expanded to the chamber, will keep the back end also centered. In a bench rest rifle with a custom tight neck chamber, everything is already held centered but not so with generous factory chambers. Richard
