I always hear talk about getting the scope mounted as low and close to the barrel as you can, which I guess makes sense from a physics point of view. But how important is it really? Is the reason for saying that because it makes it easier for the proper cheek-weld? In trying to mount a Nikon Monarch on a Savage rifle using low rings, I'm finding that the ocular bell is too low and hits on the bolt, but the elevation for the objective is fine. I guess this means I'm going to have to go with higher rings. What is the downside of doing this? Thanks for your help.
