As everyone else has said I've yet to hear of an SPR built rifle not shooting tiny groups. My 6.5 saum they built will shoot pretty much any 6.5 bullet sub 1/2" groups.
Greg has done two rifles for me. He was recommended by Terry Cross when I reached out to him about finding a local smith several years ago. I visited his place twice and knew I could trust him after speaking with him, and I have been extremely happy with his work. He's good people.
Just dropped off my 7mm STW Sendero with Greg. We sat at the bench over the rifle and discussed for 30 minutes what my goals were for the gun. He took notes and answered all my questions and gave suggestions. Super nice guy and I look forward to getting it back when its ready!
