I have a Rem. 700 Sendero SF1, SS fluted barrel. It was orginally a 7mm Rem. Mag and it has been re-chambered to 7 STW and installed a muzzle brake. It has less than a 100 rounds through it. Before I took it off, to build another gun. It would shoot 1 1/2" at 300yds, with no problem. I will take 175.00 shipped.
