Re: Rings & Base which ones?
I have not had anything to do with those Sakos. If they have the Sako dovetail on the receiver I would look at the Warne rings for Sako, I have them on my old magnum length Sako and the 75's and they are very strong and simple. They are simply two pieces of steel, very sturdy and they clamp directly to the dovetails and their bottom is wedge shaped like the Sako dovetail.
Nikon Titanium - have shot them quite a bit, do not own one tho. Not a scope I would feel I had to own, their Tactical is a stronger model and much better for LR. In my opinion the Nikon and the titanium Burris Mr. T are good scopes but I believe the advertising guys got involved with these scopes - not sure they really offer something we need. Have to wonder if the extra $ are really there or worth-it compared to their standard scopes.
