BEFORE fooling with a new scope, take the scope out of the mounts and remount the mount. Bed the thing, weld it to the barrel, loc-tite the screws, torque them down and re-torque them. They (NEF's) are insanely hard to get a good permanent non-moving mount. Then mount the scope. I would give you the URL of a man with a step by step guid to mounting the scope mount and free floating the barrel, but he has switched ISP's and hasn't yet reposted his pages (at last word he was making everything easier to follow).
I hope you the best, my 243 NEF won't shoot better than 0.75" at 100yds with 100gr Winchester factory ammo. Someday I might have time to work up an accurate load.
