Neck tension

[Koda]

I plan to anneal with a blow torch as per (Dan Newberry) https://m.youtube.com/watch?v=qlIjQ05aKzk
some rounds and try the same test in a couple days.. will report if my findings.

The torch method works great but the smaller cases might get too hot to do by hand. Many chuck them up in a handdrill with a socket, I use a Lee case trimmer stud and shell holder. The handdrill rotation is more consistent exposure to the flame too.
