This is my first 7 stw build. Mark Phar of Tumbleweed rifles in Round Rock, TX put it together for me and I am very pleased with the fit and finish. Going to break the barrel in today after work. Hopefully it shoots as well as I am hoping it will. The specs: - Winchester 70 action w/ claw extractor made in U.S. blue printed, trued, and bedded, Squared bolt face - Kreiger 5.5 barrel, 9" twist, at 28" long, fluted, threaded for suppressor that's on order - Boyd's laminate stock Any thoughts on loads? I'm planning on trying out some 140's and some 162's? Planning on sticking with retumbo or other hodgdon extreme powders bc of the temperature variability in TX, I have read that RL 25 works well.
