I have a 30mm viper on a Winchester Mogel 70 300 wm and my ruger steel mounts just failed. Vortex doesn't show a Winchester long action mount. I am looking for suggestions on replacements. I do not want more dovetails that turn in. I have used the ruger steels for 20 years with no issues but the new set of rings doesn't seem to be as tough. came loose at the back and the dovetail in the front now has play. Didn't when mounted??
