Does anyone have any experience with the barrels and workmanship at THE MONTANA RIFLEMAN in Kalispell, MT? I am thinking about using one of their barrels and having a .35 Whelen built on a stainless steel classic Model 70 action. Do I really need a 24" barrel or can I get all I need from factory loads with a 22" barrel in the Whelen?. What barrel contour specifications would you recommend? I want her built light. CP.
