Re: Dies and neck tension?
You can use most neck sizing dies to partial size -plenty enough.
You can use a redding body die/JLC for the rest of the sizing in a seperate operation.
You can use Sinclair expander die mandrels for post neck sizing -sizing, in a seperate operation.
You can use a Neil Jones decapping tool to punch primers in a seperate operation.
[I do everything seperate of each other]
