I am mounting a Leupold IER "scout" scope on a 45-70. I'm thinking of using the Leupold quick-release rings. The question is: medium or low mounts? I'm thinking low is probably best to maintain a good cheek weld and stay low and close to the barrel. I know there's more than a few of these setups out there so I figured I'd ask and see what other's experiences have been!
