Thread: Increasing case neck tension

I only fl size now but when I used Lee collet dies I would anneal case and give it 2 passes on the collet (turning case about 45degrees between passes)

I always turned the die enough so that the wee ridges created by the first sizing were covered by the petals and therefore mostly eliminated with the second sizing. The ridges are probably not an issue though.
The Lee collet die creates the most concentric sizing of any dies. I too now anneal and FLS with every firing.

Interesting regarding the hard brass. This is my first time running Norma brass so that could explain why it is the first time I have come across this issue before.

I never thought of that. I will try this tonight!

Be cautious if you anneal and then run them into a Lee collett die, you can get collapsed necks as the soft brass you have created sticks to the mandrel and turns the case neck inside out. Ask me how I know.
Lee collett is quick but not my now preffered method.

I wouldnt call Norma brass hard? your results may vary from mine.
