[QUOTE="J E Custom, post: 1768044, member: 2736"] The 7 WSM chamber body is longer than the 300 WSM at the shoulder to neck dimension by .056 thousandths so when sizing the 7mm neck, you "MUST" stop sizing the neck @ 1.856 instead of 1.802 (Like the 300 WSM) When you do this there will be a portion of the neck that is still 30 caliber (A false shoulder)to head space on for fire forming.
