I have the same rifle. It had a VariX3 2.5-8 on it when I bought it that wouldn’t hold zero and had coating rubbed off the lenses. I thought it might have been the bases as one screw hole was stripped. Tapped it out to 8-40. Sent scope back to Leufold and they replaced it with a VX3 2.5-8 which then it killed after about 100+ rounds. Sits scopeless now and I still haven’t figured out what I want to replace it with. Thinking a Trijicon LPVO. Used Talley extended bases and screw lock detachables and probably will again.
I have had a few hard kicking Winchester 70 classics that broke a bunch of scopes...the culprit was a big discrepancy between what the front and rear bridge height actually was and what the base manufacturers thought it should be. No matter what bases I put on those rifles, they broke scopes because the front/rear bases ended up at slightly different heights. I finally bedded the bases to level them...no more broken scopes.
Might not be your problem, just thought I'd mention.
