Has anyone done this? I've noticed that the Zeiss Conquest scope on my Talkeetna is sliding forward ever so slightly (after 100+ rounds). I have Talley rings (lapped) and torqued the screws to 18 in-lb but have thought about copying D'Arcy Echols' approach to this issue by cutting a cone in the rear of the rear scope ring to match the cone of the ocular bell housing. Once done, I'll gently slide the scope forward a fraction until the bell housing makes contact with the ring. The flat of the cone won't damage the scope and it'll prevent the scope from creeping forward any further.
