Yes, IIRC., that just happened not too long ago. A few die makers will do it in special order; you must call them. On my last custom build, I had a sizing reamer made, and my GS custom-made all my dies, including a hydraulic-forming die, using a Newlon blank die and a Whidden plunger kit.According to Whidden, they are not accepting orders for die sets including the hydraulic forming dies.
