I am in process of converting .243 Win brass to 6.5 Creedmoor brass, conversion has gone well except for one brand (PPU) of cases that had too-thick necks. (see http://castboolits.gunloads.com/show...from-243-brass )
The neck tension seems to be very high, what should the neck ID be? I measured the neck ID on the reformed cases to be around .260, is that too tight? I had to pull a bullet (no powder!) and it took 4 hard hits on an anvil to break the bullet out.
Thanks in advance for your help.
