[QUOTE="MagnumManiac, post: 1433751, member: 10755"] If shoulders are being pulled forward by an expander ball, the simplest method to fix this is to dry lube the ID of the necks with powdered graphite. I run a proper sized nylon brush into the necks a few times prior to sizing with expanders. Only a light dusting on the brush is required. I run many belted mags, including 3 Weatherby cases. Weatherby case design appears to repel sizing forces and springs more than normal shoulders. I have this same issue with 270 Weatherby, 300 Weatherby & 375 Weatherby. The 375 was the worst culprit due to having an absolute minimum chamber, just .002” above minimum spec in head to shoulder. My die would NOT size the case to absolute minimum, only .004”, so after trying several methods I bought another shell holder and turned .010” off the TOP of it and using feeler gauges was able to get to minimum spec where the cases would chamber. I also do not think you annealed your cases correctly, it takes heat AND time to do this correctly. I use 600*F for 6 seconds to anneal my brass, and get that perfect deep gold on the necks and partway into the shoulder and the rainbow about 1/4” below the shoulder/body juncture. Hope this helps and gives you some insight into what MAY be the issue. Cheers. :) [/QUOTE]
