Yea, I'm thinking I will either have to buy an expander mandrel or a new die. Sizing without the expander is measuring about .011. That's way to much neck tension I would assume. Neck tension with the expander is some times in the .001 range so I'm afraid it wouldn't be enough. Would the .261 mandrel after sizing without the expander leave enough neck tension?
