Just got my new dies from Neil last week, so he is still alive. Try email email@example.com
or contact from his web at www.neiljones.com.
fax is (814) 763-4228
Other guy might be Jim Carstenson (JLC Precison ad in Precision shooting). he can make FL size die off your fired brass or from your chamber reamer. Uses a body insert squeezed down in the die. He also converts any factory die to bushings for $35. His dies are not micrometer adjustable I do not think. Never had him make one, just convert to bushing for me.
Keep after Neil Jones for best dies in my opinion.
