Based on the fine recommendations of the 'Fire I did a little research and found what I may be looking for.
Weatherby Vanguard H-Bar
20" #3 contour barrel threaded for a suppressor(if I ever get one...).
Hinged floorplate, only 40" OAL for the rifle which is an inch shorter than the Montana. Sounds about perfect and I see they go for under $600 on-line.
