I've got a Savage 111 in 6.5-284 Norma. When I first purchased it I bought a Talley aluminum one piece 20 MOA base for it. I put an unexpensive pair of Blackhawk aluminum rings on it temporarily until I could buy a good set of steel rings. I normally buy Nightforce bases and rings but this rig will have a 1 inch scope and unfortunately Nightforce doesn't make 1 inch rings. So, I bought a set of Mark 4 Leupold rings for it. While looking at the new rings I read the instructions that came with them. It said that they did not advise using steel rings with an aluminum base. Why would they make that recommendation? Do I need to wait and get a steel base for the rifle before mounting the Mark 4 rings? Anyone had a problem with mixing the two metals?
