John, I have used them in the past on some of my highly polished rifles but these days, I'm more into Form Follows Function!
Because of this, the only Conetrol rings and mounts that I possess are on my HB Tikka .222 or have been transferred from another, now sold Tikka M55, on to my Brno Model 1.
They are a great looking set-up and I have had absolutley No Problems with them allowing any scope to slip but these days, I don't want to find a scope mount/ring problem, out in the boonies! Sorry John but I can't remember what hard recoiling rifles, I've had the Conetrol's on in the past?
