Thanks, I hadn't thought of the 7X65R. I compared the 9.3X74R and thought that it was case I was looking for but the rim is smaller than the 30/40 and I'm not sure about extraction. As to loads (if I get that far) it will be mild cast bullet loads for an '06. The Krag action is a nice one but not one that I'm going to try max loads with. I would like to get it shooting even if it is a target/plinking load.
