I had Leupold QR bases and rings on my old 458 Win. Mag., and they always worked perfectly and still do. These are NOT the Warne-built QRWs, which as not as good.

My custom Echols-built 375 H&H carries custom detachable rings from Tom Burgess, and they're not only beautifully-made, but totally repeatable and reliable.

I have fixed, non-detachable custom Echols-built scope base/ring mounts on my 416 Rem. Mag., and I like this system the best of all.............
