Ok. So what I'm hearing is that a case can't separate at the shoulder and the shiny ring after firring is nothing? I have never had a case separate at the shoulder/body junction. No harm is done with a case separation in the body. The head/web area is much more dangerous. I'm thinking that when I for any new bras I should also make it just. Short enough to close the chamber. Yes, control how much the FL die pushs the shoulder back. Not the FL sizing like I have been doing. Correct.

How does a long bullet touching the rifling help me fire form. I understand it'll hold the case tight to the face of the frame. Eliminating the backed out primer? Is that all its supposed to help with? It may help reduce the amount of stretching of the brass, but the firing pin strike can push the bullet into the case deeper. It may or may not work, keeping the brass from stretching. Stretching of the brass is what causes case separations.

Hope this help.
