I would think your talking about Steve Wald of "Wald Precision Rifles" in Mandan. I have had Steve do two rebarrels with two of Nates brakes. I think he does great work as I am very happy with the 7RM & 6BR he did for me this past yr. . I believe he does coordinate brake work with Nate & the two communicate regularly.
Steve work shows the attention to detail I value. I will continue to send work his way. I have seen Nates work & agree that he does top shelf work, but have not had Nate do anywork for me. He is in pretty hi demand.
I found Steve by default of Nate being busy. A shooter from the US Palma Team uses him (Steve) and recommended him. In short I think Steve is a great smith, he also turned me on to Brux Barrels, which I have been very impressed with also.
