Is there a procedure that reforms 7.62x51 and/or 308 Winchester brass to 358 Winchester that does not require fire forming or otherwise using consumables during the procedure? What I seek is a method where brass is sufficiently reshaped to allow 358 handloading to occur as though the case were originally 358.
I'm not concerned that the reformed brass might not "look" SAAMI. First firing accomplishes that. I'm trying to determine whether brass can be rendered "close enough" to be loaded as would actual 358 brass.
