Thread: Whats your neck turning process?

Some neck turning questions.

I'm currently borrowing a Sinclair 1000 from a mate. Using my Lee shell holder. Unless you tighten it down pretty hard, the case sometimes unscrews itself when the cutter takes the first bite. Anyone using a K&M case holder experiencing this ?

Also, is there really a benefit to having carbide cutter and carbide turner mandrel ? It's only cutting brass after all...

Lastly, I see the K&M has a cutter on the mandrel to deal with the "doughnut". I'm turning Lapua brass that has probably been fired 15 times after initialy been turned. Only taking a tiny bit (around 1mm) off near the neck shoulder junction. How real is the doughnut problem in non magnum calibers ?
