Glad Wes got you set up. What I’ve found with the mil surp brass is the machine gun headspace is quite a bit longer. I have gauged brass at .010-.012 over SAAMI headspace before sizing. Therefore you can’t setup your dies as you typically would with “usual” brass. This is where a micrometer case gauge setup is invaluable - you can measure the datum and keep adjusting until to SAAMI spec.
