A little lube will come in handy along with a little tack when pushing the shoulder back. All lubes are not the same. IMHO Imperial sizing wax or Unique case lube are perhaps more favored for there lubricating quality. You will need some means to measure head space to insure you are pushing the shoulder back enough without going to far.
Then of corse The OAL will need to be trimmed to length. Your choice to weather the trim op is accomplished before or after necking down & pushing the shoulder back.
