Thread: Seating stem

So after I pulled 2loads from the trial run the other day I realised that neck tension is a major problem for me. It took 30odd whacks of the bullet puller before they started to move.
And the necks are down about .268" to.271" after being pulled.
After being fired they measure .275" give or take a tad.
And after neck sizing they are tighter than the 'pulled' ones. ( battery run out on calipers before I could measure)

So now I know I have a problem, what is there that can help me??..

Neck bushing die?
Lee collet die?

It's for a 270wsm so Lee collet die is out of question unless I send away for a custom one.

Who makes a something to correct my problem?

Cheers in advance
