I'm shooting a 300 RUM with a Schmit & Ben 3x12 scope. My current ring and base set up includes Burris rings with the plastic inserts and Leupold bases. After my groups disengrated, I noticed some play in the front ring and base. I assume the recoil and heavy scope have something to do with it. Wondering if anyone has any suggestions? A friend recommended a double dove tail set up and stated it should handle the recoil better.
