Time will tell - Weaver Grand Slam Steel Scope Base

I am very impressed with the material quality and workmanship on theWeaver Grand Slam Steel Dovetail base made specifically for the Winchester 94 (A/E models). I am not wild about a key design feature howeverI. I have a serious question about the method utilized to mount the rear ring to the base. It is held in place by the 2 windage adjustment screws. Although the ring seems to be secure now, only time will tell how it holds up. I put 75 rounds through the 94 at the range last week and it was still tight afterward, however this is not much of a test.
