Can a 9.3x64 case be formed down to the 7x57 case size sucessfully. Will the standard bolt head except the bigger case head with out it being turned down. I do have genuine reason for asking this as I want to create a thick neck case to look at a few accuracy issues. I have been handloading for 35+ years so understand the safety side of load developement, release clearance, tapered neck idiosyncrasies, etc etc etc. I would like to know if the case head will re-form and the rim issue before I buy the expensive brass.
