In a lightweight rifle like the kimber montana the 325 WSM is an excellent all around big game rifle. With 220gr bullets it is every bit the equal of the 338 win mag and with 200 gr bullets it will outstep a 300 win mag. Basicly it sits right down the middle between the 300 win mag and the 338 win mag and that is a very good neighborhood to live in when it comes to big game hunting. I had a kimber montana and really like it. It was pretty much everything you would want in a big game rifle, lightweight, accurate, handy, and fairly weather proof. The barnes 200gr TSX is a real winner out of it for all around use. A budy of mine guided a hunter this year who took his brown bear at about 20 yards with the 220gr powerpoint load, was pretty much a bang flop with no follow up shots needed.
