FWIW, I have the 300 Win Mag 110 BA
I used Devcon as a "Gap Filler" between the scope mount and actions. I put release on the action, Devcon on the bottom of the mount and tightened the screws to 10 lb's. This makes for a very solid mount.
I prefer to lap all scope rings to ensure maximum metal to metal contact that is parallel with the tube.
The Pelican/Harddig cases are great for keeping the rifles well protected. I wonder if Savage took the case size into account when laying out the 110 BA? They barely fit into them.
