Does anyone know ballpark about what one cost? Will SSK accept a Kimber 300 WSM as a donor action providing it works properly or Winchester only? I do like short barrel handy rifles and I'm at a crossroads. Put money into a CZ for AHR upgrade (no current issues with this rifle) or buy a B&M made from the action up. I do alot of mountain hunting and maybe this year in grizzly country, so a trim heavy hitter would be nice. Thinking something 416 cal on up. Thanks
