Thought I would start my own thread on this.
Started out that my Grendel reloads were growing in COL by 0.005" when fed from the magazine by either fully pulling the charging handle and releasing or just popping the bolt release to chamber up a round. Then came the Lee Factory Crimp die. Slowly adjusted from recommended lighter crimp to "make your own deep cannalure" crimping. No dice. Still bullets sliding FORWARD in the cartridge neck the same 0.005". I was gravitating toward replacing the standard carbine spring that came with my lower with a reduced power recoil spring.
I think that I had read somewhere on here that somebody was increasing their tension by sizing without the expander ball. I tried that and immediately the COL growth stops at only 0.002".
I am going to give reloading a go by just sizing with the expander ball out and see what happens.
I will report back when I eventually get around to shooting again.
BTW- thanks for everyone's input on the other threads where I have thrown this out there!!
