I'm by no means a smith or expert, but my optimistic opinion is that if you can get the coat completely out of the rings you may be able to get enough grip to stop the sliding depending on how thick the coating on the scope is. I have no idea how thick Duracoat is or how soft so my opinion may be worthless. My real world logical opinion is no. Following recommended torque settings on rings has never worked for me. It's always taken a bit more to hold them there rock solid. Like I said I'm no expert, just my thoughts. Maybe someone with more knowledge and expertise can lend a hand. Try it
maybe it will work
Edit: Not sure what bullet/powder combo you're using, but my 7mm RUM with 84.5grs of RL-22 pushing a 154gr SST provides a heavy, but slow and smooth amount of recoil. It would probably work if your gun shoots like that. If it hit's like Thor's hammer I'd be more inclined to think it won't work. Don't worry my opinions will probably have plenty laughing as well...I don't care as long as I can learn something from it lol.
