You only have two main ways to do this.
1. Like Boss Hoss said, you must have the matching resize reamer to your exact chamber reamer. Then most smiths can make you a FL size die matched to your chamber, heat treat it and good to go. Cost will be about $175 up and your cost for the reamer unless the smith just happens to have your exact chamber reamer. Do not let anyone feed you that crap about using your chamber reamer to make a FL size die. Totally bogus and abosolutely zero resizing.
2. Dies from fired cases. Neil Jones and Jim Carstenson (JLC Precison on www.6mmbr.com
under "Tools", also does some I believe.) Neil needs 5 cases fired 3 times or a copy of your chamber reamer print. He will make either an inline or 7/8x14 or 1 inch press die that is NS only initially if all you have is the chamber reamer print. You fire the cases 3 times, send the NS die back along with the cases and he makes an insert to make the NS dies into a FL size die with neck/shoulder bump bushings (only one that does this) custom honed to your chamber. Cost is about $175 to $200 depending on which die body. My 338 Lapua Ack Imp dies were on the 1" die body and 3 shoulder neck bushings. Figure anywhere from 45 days to 3 months.
3. Heard the Jim Carstenson does it similar. I know he can take a redding body die, convert it to FL size with bushings custom honed for $80 if your wildcat is off standard Redding body die.
4. The Harrell brothes in VA (go to BR central and look under dies and muzzlebrakes) have a CAD process to do certain dies.
5. Die mftrs will normally need cases or reamer print and if using reamer print it will be "close" but not exact fit to chamber. Cost is $150-300 and 10 weeks to 10 months depending on time of year, mftr and backlog.
