I just bought a new Burris fullfield II 3X9 - 40 to replace the old 4X Redfield on my Husqvarna .270. I'm using the original weaver detatchable base. The problem is that the eye bell has a greater diameter than the old scope and I need to get another 1/32 - 1/16 of an inch clearance to bring the bolt back with out scraping the bell. I'd like to do this with out changing out the mounts/bases. Is there any type of shim out there that can be used? Any suggestions?
