Do I need to resize the neck when I full size?

I did a partial resize on 308 brass where the die just touched the shoulder and the primer was pushed out and the expander ball pulled back through. These haven't been primed or loaded as of yet.
I bought another 308 and want to shoot them in the new gun, so am thinking I need to full resize for the new gun before shooting the brass. The question is, can I take the expander ball off and just do a full length resize, or do I need to keep the expander ball still in the die?
thanks
 
You need to keep the expander in there. The die will reduce the neck to slightly too small then the button expands it just right.
 
Full resize before fireing in the new gun, then neck size. Keep the brass from each gun seperate as it will be fire formed to each cspecific chamber
 
Generally, I'd say to full size it, but you could also simply check that the brass will chamber, and if the brass chambers, then load a dummy round and make sure that that chambers, too. Try a couple of rounds. If they all chamber, then you are styling...
 
What sort of a die are you using? I'm not getting someting.... If the brass went in far enough for the shoulder to touch the top of the die, it's sized.
 
I think you need to get someone to show you how to re-size a case. I too "am not getting something" here. Your post and the questions make me completely confused about what you are doing.

Don't remove the expander, as mentioned the die neck section actually squeezes the neck too small and it is then 'expanded' to the correct size when the expander is pulled back through the neck as the cartridge is drawn back out of the die. This allows for a consistent inside neck diameter no matter the variations in neck thicknesses.

I don't think there is confusion. OP has stated the case exactly as he sees it.
The key here is to first check to see if the brass will go into the other rifle. With it being sized to just touch the shoulder, the diameter will be sized, so just a matter of whether or not the case is too long for the other rifle.
If it won't go in the other chamber, then allow the die to turn in until it hits the shell holder and resize. Leave the die intact for doing the further resizing.
 
Thanks for the suggestions. I should have been a bit clearer on my set up in my first post. I set the die so that the shoulder wasn't resized. I had marked the shoulder and kept adjusting the die downwards until is just touched the shoulders and then backed off a 1/16th of a turn or so. The result is that the shoulder of the brass wasn't affected. I was after neck resizing, as I was planning to always use the brass in the same rifle. Now the goal posts have changed with the purchase of the new rifle.
thanks again.
 
Well - If the brass chambers - use it! Your new rifle may have a larger chamber than your old one, so its worth a try. If it doesnt chamber you can partially resize them to fit. In the end, you can partially resize to your tightest chamber, allowing you to use the brass in several rifles. Beats neck sizing and segregating brass.
