I have a BBR in .30-06 (not the varmint barrel) and I've been extremely happy with it. For all intents and purposes, its a Weatherby Mark V action. Its a heavy gun but shoots great. Never tried to adjust the trigger because I've never found a need.
Not the exact info you're looking for, but I've been happy with it. The one thing I have heard is that magazine's can be very difficult to find, so don' t lose it!
