Remember that you are going to need two reamers

Finish reamer for the rifle chamber

Die reamer for a full length sizer that will have to be made, which HAS to be smaller than the finish reamer

JGS and Manson will do a great job for your, with a couple of month leade time. Hendrickson will take a year.

PTG went through a rough time a while back when Dave had back surgery. I think that things are much better there now.
