Hi. I'm setting up an elk rifle for my wife. It is a Rem. mod 700 in .270 I'm using Leupold QR bases w/ med rings. The scope is Nikon 3.3-10x44. I can't seem to get the scope to move far enough back to get proper eye relief comfortably. I was wondering if anyone had any suggestions. Are there different mounts that would work better? Thanks.
