[QUOTE="Greyfox, post: 813689, member: 10291"] I have the same thing going on with mine. I use 89.2 gr Retumbo with a 300 Berger. Cases will separate after about 4-5 loadings. Cases stick if I don't push the shoulder back. Using the Hornady Lock and Load tool, new Lapua reads 4.317", fired brass, 4.325". I push the shoulder back a couple of thousanths. No pressure signs. 2700 FPS. Sub .5MOA groups. There is definitely something going on with the chamber on my rifle. I have to get back to it and figure out what's going on. I've been working on a 300 WM. [/QUOTE]
