[QUOTE="Michael Eichele, post: 246143, member: 1007"] Most shooters that neck size that have seen dramatic accuruacy improvements missunderstand where the accuracy is coming from. Some, and I emphasize some of the time the bulk of the accuracy improvment seen from NS vs FL sizing comes from the lack of runout caused by NS. When using standard dies and reloading practices, FL sizing tends to cause alot of runout in the cases from the expander ball. When guys neck size with a bushing style neck die, this eliminates that issue and accuracy goes up causing some shooters to think that the fitted case was the sole reason for the improvment. I am not going to sit here and tell you that a properly FL sized case in a sloppy chamber is as accurate as one that is NS only, but after a couple of firings, the brass does get hard to chamber and feeding can be an issue. This is why I prefer to use a body die for the body and a neck die for the neck. Keep it simple. [/QUOTE]
