I prefer M70's over Rugers also. The only thing I would change is the Talley LW's and go with detachable mounts since you are putting iron sights on it.

I like Weaver style steel bases and Warne rings with QD screws and not levers. I just carry a wrench in my hunting pack. Talley's QD's work fantastic, but are too high for my liking. I do not like levers as they seem to catch stuff while out hunting.

My system is not a foolproof return to zero, but then I have never needed to remove a scope to use open sights in an actual hunting situation. The zero is never far off when I have tested it at the range.
