[QUOTE="wallypedal, post: 648642, member: 7107"] jlamb, you brought up this old thread, and I feel obligated to tell what I did since the original posting time. I did buy Bellm's headspace measuring setup, and discovered that my 'garage' measuring technique on the Encore wasn't accurate. What I had perceived as .001" was more like .003" - still within standards, but I was over-resizing by .002" or so. I also bought an RCBS X-sizer and followed the directions, setting it up so that the cases were sized just enough. My case life jumped dramatically. I have shot new cases prepped this way a max of 5 times so far, with no signs of separation, and overall case stretch stopped after the first couple loadings. A couple more things - my first brass was purchased once-fired, and it was good, but I do believe some of it had been fired in chambers larger than mine. That means there was more initial stretch that got squashed back the very first time I resized. My real worry was case separation, although I emphasized stretching in the post, I was seeing the the hints of case separation after only 3 or 4 loadings and became skilled at shining a little LED light down there looking for the circle shadows that show before a crack even starts. Starting with new brass fired only in my Encore, and following the techniques listed above, I'm not seeing those shadows either! Wallypedal [/QUOTE]
