[QUOTE="VinceMule, post: 2723224, member: 122164"] I had a Larry Willis die for years, never used it, even on rem factory chambers. I have had custom chambers were the reamer was ground with only .002 clearance in the web, then the use of a small base die was needed. Measure with a micrometer that measures to the 0.0001 Right in front of the belt New brass, measure 5 pieces, NOT just one piece Fired but does not need full length sizing Fired but increased bolt lift/scuffing on the case head Often, a Full length sizer will not size the brass down far enough in the web. I have a shell holder where I have used a grinder to remove .003 off the top of the shell holder. This usually does the trick with the sized case going from tight to close the bolt to an easy bolt closing. Go to ebay and buy a Shars .0001 micrometer 0-1 inch [URL unfurl="true"]https://www.ebay.com/itm/300514233656[/URL] [/QUOTE]
