I recently found some neck turning equipment for a really good deal and couldn't pass it up. I am knew to neck turning but I would like to have a general discussion about the topic. I have read that some reloaders turn to get rid of high spots on their necks. Is there any benefit to this? Also what is too thin for say 300 Win Mag brass? Finally I have read that neck turning can help with neck tension. Any input and discussion would be appreciated.
