I'm trying to get my head around the whole neck tension thing for precision handloading. Here is my theory, please tell me if I'm wrong.
So I just spent all this money on a neck turning kit from K&M. As I'm going through the process, I realize that the reason I am doing all of this is so that when I run my brass through my bushing dies, I will get uniform next tension because the thickness of the brass is the same all the way around and when my bushing squeezes the neck, it will be uniform all the way around the bullet.
Then I start thinking about how full length sizing dies run an expander through the case neck to even out the inside of the neck. Well, if the inside of the neck has uniform tension on the bullet, the only down side is that I can't control the neck tension with bushings. Furthermore, if using and expanded ball evens out the neck, why bother going through the whole neck turning process? I mean, who cares if the outside is uneven as long as the inside of the neck is uniform on the bullet right?
So I start to look in to expander balls and I come across Whidden Expander Kits. If I can order a kit with different size expander balls and control the neck tension, why am I screwing around with all of this neck bushing / neck turning business when I can just get the kit and have the same results?
What am I missing?
