Redding doesn't offer it and I really doubt Forster will do another manufacturer. Hornady also does it. However, you have to order it so that they can do it before they heat treat it. At least that was the explanation I received from them when I asked if I could send my 6.5 die in to be done.
It is a great option though. I have a Forster .308 die that they honed for me. Results in really straight ammo.
