Neck sizing with FL die
- Thread starter cjd966

Thanks, but how do I know if it's right? I have tried a few now and I just kept adjusting the die down until I can see that the neck has been resized all the way down to start of the shoulder and then left it there... is that right?
And should I need to lube the case for this? I tried one without lube and didn't push it in very far before it felt like it was going to stick - does this mean I need lube, or does it mean that I've turned the die down too far and am in fact full length resizing?
[edit]
Also, I am having a hard time pulling the case back out - once the depriming pin has pulled right out of the die (and the collet was tight) - is this because I am using Mica, or do I just need to apply more of it? Should the case pull back out relatively easily?

i would try leavong a gap between the base of the shell holder and the die about the thickness of a nickle. all you need to do is resize the neck about 3/4 of the way down. as long as the bullet is held tight its enough. if you size to the shoulder you will need to lube the case. all in all i would recomend a lee collet die if one is avalable in the calibre your working with.
You will see the marks an the neck, start high and work your way down, I take mine as far down as possible without getting into the shoulder.
You may need move your depriming pin down pending how long it is or what dies you have.

Set your die down to within the thickness of a dime.
With this method you are actually sizing the body of the case as well as the neck, you're just not pushing the shoulder back.
If you want to truly "neck size" only you need a special neck sizing die.

It's an easy low tech method...
Take a jiffy marker and colour the neck and shoulder area
Back your dies out a few turns
Put case in shellholder, raise it up and extract, see how much the marker has wiped off the neck. Check to see if it fits your rifle chamber.
Make sure the case fits and that the neck has been resized enough to give good neck tension, and you are done...

"Check to see if it fits in the chamber" Start with your die in the recommended factory position, back it out 1/8 turn, size case, try in chamber. Repeat in 1/8 turn increments until brass does not chamber... Go to previous setting, record for future use.
Lubing the case and the inside of the neck is essential - try some other type if mica isnt cutting it. Yes - the die should retract without too much force, depending upon calibre. Lack of lubriction inside the neck will give the problems you describe.
