This is meant as no offense to anyone, so please don't take it that way....I don't understand why anyone would want to mount a scope on the T-3 using bases of any kind. Why not mount the scope with the supplied rings and be done with it? You have to know that by adding parts you can only complicate the issue. I have 2 T-3's (7-08 and 7mag) and have used the supplied rings on both and both shoot like the pics you posted with factory ammo. Why complicate the issue? Just curious.
