I think you would be happy with the 7mm Mag. It should fill in well for your old standby. To me the 100.00 difference would not be worth it. However thats because I don't have many 100.00 bills to spare. Both scopes will do very well at the range you are speaking of. A salesman at a gun store the other day told me that Leupold is going to discontinue all of the VX scopes. He did not know yet what they were replacing them with. I don't know if thats true or not but that was the second time I have heard that. Good hunting!
