good to hear you sorted it out mate, I had the same problem after fitting a v mach kit in my hw77 it did nearly 14 ftlb (no washers) I must say though transformed an already good rifle to a great one, phoned Steve pope at v mack he requested I sent the spring back for a coil or two removed all sorted in two weeks and shooting a constant 11.4 ftlb with rws superdomes now, great kit and a great service would recommend to anyone.
