mart,
There is NO "advantage" of a Blued/Walnut Seven,over a Montana. That in balance/handling,weight,twist rate,ergo's,throating,scope mounting or durability. Read that again.
Now to cripple those inherent heavy concessions even further,you've added schit mounts and schit glass...which is THE Dirtiest Of Tricks. Only move left in order to connect all of the Hilarity Dots,is to feed it some schit brass,schit powder and schit bullets,which also seem to be of keen interest to you.
Punt while you can and thank me later.
Hint...............
