I just picked up a Remmington 700 in 7mm STW. I have a Leupold VX-2 4-12 I want to mount on it. The problem I am having is it won't fit on STD Leupold rings and bases. The scope fits so tight in between the front bell and magnification ring that the ring won't turn. So, my question is what next best option? Should I go with extension rings or completely move away from the Leupold STD bases?
