I too had some issues with my Omega and accuracy. I also had an issue with zeroing the gun where I could not get the POI high enough. This was using a Talley one piece mount. I had to have the scope adjusted to max verticle and the groups were not really impressive. I bit the bullet and bought a Ken Farrell +20 MOA base and added Warne rings. I also did a proper bedding job (no shims) and floated the barrel in the laminated stock. Now, the gun shoots sub MOA to 200 yards. I will test it further this weekend.
