For that kind of money, you can have a much better rifle custom built. I know guys that own and shoot the 500 and its heavy.Don't know anything about this one, but I am a fan of Knight. If you are looking at the Cooper this may be worth looking at. If I were looking for a LR ML I would want to shoot this at least.
I am looking to shorten my barrel for more convenience in the woods. Similar to the Khatadyn.
