RE: which bases/rings for sako 75
Ea I gotta RUDE awakening when I returned home from a hunt in WY last month. I have a Sako TRG-S in Lazzeroni Warbird with a Swarovksi 6x24x50 PVS on it. The gun has had a KDF muzzlebrake on it since new (99). The day after I got back from WY I had my gun at work and was cleaning it and just giving it a going over after a flawless weeks work in the semi-desert area I hunted southwest of Buffalo, WY. I had the Leupold 30mm Super High rings atop Leupold bases (dovetail front, twin screw rear).
I was HORRIFIED when I felt the rear screws were both LOOSE! These were installed by the legendary gunsmith in Memphis, TN, Ed Mason (actually one of his sons probably did the work but they were raised beside Ed since they were in diapers.) They drilled and tapped a single screw thru each base and into the top of each dovetail rail on the action. The setup was properly adjusted the week before I left for my trip as well. I snugged everything up before I checked the zero two days before leaving for the hunt. And I likewise rechecked the zero on the first afternoon we got too WY, everything was fine.
Once I felt the loose screws I pulled them out and they were actually chewed up as each sharp edge thats holds onto the ring itself was cut into. Additionally the grooves in the bottom of the rear ring that is held onto by those screws were likewise chewed up and about halfway gone! Obviously this was a problem that has been growing with each pull of the trigger.
I realize this rig puts tremendous stress on scopemounts but I have never liked the antequated dovetail/twinscrew system in the first place. I replaced them immedately with Sako's OptiLok system. They are MUCH stronger and dont rely on what are basically "friction screws" to retain the rear rings. How the system held zero on the hunt is beyond me (and it worked, I took an antelope @ 367yds and a mulie buck @ 125yds). I guess the Lord had pity on me and held it on himself!!!
I am quickly replacing all my other setups on rifles with either dual dovetail setups or just tonight our order FINALLY came in from Talley. They have new CNC machined one piece alloy base/rings that should be practically BOMBPROOF!!! The less screws, joints and parts a setup has the stronger and less problematic it will be.
Spend the extra money on the OptiLoks... TRUST ME,
