[QUOTE="Edd, post: 973083, member: 30592"] There is a base to shoulder datum spec for 7mm STW cartridge and other belted cases. For the STW the minimum is 2.4538" and the maximum is 2.4608". That is measured at a shoulder diameter of .420". So based on the SAAMI specs, the acceptable growth from unfired new cases would be between maximum of .0259" and a minimum of .0089". The .020" the OP had is within that range. [/QUOTE]
