If they are the steel rings good luck with that.Unless your gun has perfectly drilled scope base holes there is no way to avoid strain on a rifle scope with Talley steel rings. I don't know why people still buy those rings and bases except for a custom application where the receiver is redrilled to a larger size. I have lapped the aluminum rings and it was not a big deal just avoid using imbedding compound. BTW I had to lap them the scope was not bottoming in the base just a few back and forth strokes and it sat in the base perfectly.
