Rey, I use one too. Just passing along what the CS guy at Warne told me when I had a screw breakage problem. I have Warne permanent mount rings on all my Encores. Mount em and leave em alone. Unfazed by recoil, air travel, road trips. Kept same zero from year. FYI, I use four rings and 6 screw bases on my guns. I knew you would like that!
