You will have to order a reamer from PTG, and send a copy of the reamer print to Whidden Gun Works, and they can make you a set of dies.I just read a post where you built one. Where did you end up getting dies and how did it perform? Any thoughts on a 30 nosler?
I have no pressure signs and like I said a 26" Brux barrel. Read some of Broz's threads. He was around 3050 fps I believe with his 300 WM. From my experience 2900 fps out of a 26" barrel is very achievable.A 300 rum would get you there in a 26" tube; the win may require more pipe length than that or higher than normal pressures.... I believe most of the guys quoting 2900+ fps from 215's in the 300win likely are doing both.
