Re: 300 RUM scope mounting??
I use the Badger and Leupold Mk 4's. It's nice to be able to take the scope off and re-mount it and not lose zero and it's a lot easier to carry a spare scope on a hunt. Just grab any scope off another rifle and pack it along, set it up if the need arises and if not just plunk it back onto the "donor" rifle upon return if it wasn't needed.
I skip, flop, roll, slide, drop and drag my rifles and have not lost a zero due to a ring or base coming loose. Some of my scopes have some pretty deep "character" marks from encounters with rocks, trees and 4 wheeler parts but these little bangs and scrapes are simply no worry with the tactical style mounting systems, zero remains at zero.
There is no way I'd ever go back to the less durable mounting systems.
