I had this built on a Mark V "Ultramark". It has a 270 Wtby 26 inch Shilen Stainless tube on it. The barrel was made to digest 90-100 grain bullets. The most accurate rifle I have ever owned. It has poked 5 shots that could be covered by a quarter. I haven't hunted antelope or yotes in years and need a couple righty rifles for my kids who aren't backwards like Dad. This has one of the nicest pieced of wood out there. Has some dings and scratches because it has been hunted, but nothing into the wood, just marks in the finish.
