Hey, I´m thinking of changing my barrel to a shilen cause I heard they are one of the best. I am building a rifle with a Long Weatherby Action and I want the rifle to be incredibly precise so as to shoot game at 500yds and paper at 1000. I really want to make it a 300 win mag but I am not sure about the contour, length, weight, etc. Since I live down here in Mexico and don´t know any qualified gunsmiths here so I tought of ordering my Shilen barrel completely finished with chamber and everything. What do you guys think.
