[QUOTE="bruce_ventura, post: 1076367, member: 34084"] This advice sounds unsafe to me. I would not do it. The case may not headspace properly on the small shoulder left by resizing the 300 WSM case in a 7 WSM die. An incorrect headspace of up to 0.10" could result, which could lead to case rupture. For example, I know for a fact that resized 300 WSM cases do not headspace correctly in my 7 WSM chamber. I resize, fire form at low pressure, and then check headspace with a Wilson headspace gage. Only then do I load the case to full pressure. [/QUOTE]
