So I am building a 6.5 x 284 that is chambered specifically for lapua brass. I am trying to decide what dies to go with. I have a few redding type s bushing neck and body dies and I seem to like them but I have noticed after a few loadings that the brass at the bottom of the neck seems to increase in thickness. I don't quite know what to think about this or how to feel about it. Has anybody else experienced this and have you found it to cause issues with ES? What dies would you go with on this build? Thanks for your feedback, Cruizin.
