[QUOTE="bigngreen, post: 385084, member: 13632"] I know my dad seats the bullets for fire forming loads long so as to keep the case in proper position and that is what I've always done. But I have a 270 WSM that had like 9 thou of head space and I was stretching the heck out of it the first firing and I'm thinking that with a lubed case and reduced load I would have moved brass from the length of the case as apposed to thinning the web, Norma cases thinned .008 in one firing and were junk at 3. Win brass was thinned out .010 at 8 and Rem brass was thinned .002 after 20. So is the difference in what the cases will take maybe have to do with how well they conform and grip the chamber wall, the Norma is obviously softer and I would think have greater tension on the chamber wall than the others thus failing faster at the web. Since this was a Savage I re set my head space of a gauge and am in the process of getting a new batch of brass ready. In the brass I have already fired I went from .010 of brass movement to only .002 in new cases, which corresponds to my head spacing. [/QUOTE]
