After only FL sizing since I started reloading, I have finally tried neck sizing. I noticed that when FL sizing my 280AI brass in a Redding type S FL die I was unable to bump the shoulder, however my brass still chambered fine. So I thought, maybe I don't need to bump the shoulder and decided to try neck sizing only. I got a Redding neck die, put the bushing in, but I also ordered the carbide expander button. IMO, the carbide expander button is a nice upgrade to the neck die. It is allowed to float on the stem so theoretically it won't bend necks. Anyway, I have noticed that after 2 firings my brass still chambers fine. How many firings can I expect before I need to run them through a body die or FL die?
