"...so I really cranked them down."
Don't do THAT any more.
If scopes were slipping in the SS rings one thing to try would be scuffing the inside of the rings with some coarse abrasive paper.
I did scuff them and they are lapped first and then cleaned off good with rubbing alcohol. After the lapping and cleaning I scratched them a bit with a hex key after they slipped the first time. I'd set them somewhat light around 20 pounds initially. Obviously it wasn't enough so I tightened them up. I didn't go full gorilla on them but those scopes have a fairly heavy tube. I know a lot of manufacturers recommend like 18 pounds but I usually go tighter than that.
This last one shot great for a while being fairly tight and then went to crap. I've had some scopes that acted weird when too tight but I notice it right away. I don't think that's the issue here. The same inertia that makes them really want to slip forward I'm guessing is unseating a lense or something. I usually only go as tight as I can cranking on the short end of a hex key for leverage.
