The Omega is a sabot/bullet gun. It will sometimes shoot conicals but that is not what it was designed for. The guys that are having all the trouble are trying to shoot mostly conicals. I don't think you will find many sabot/bullet shooters that have much trouble getting decent groups. I have shot three 300gr. bullets in Harvester sabots with my five power scopeinto 7/8inch at 100 yards. Not all the time but when everything clicks it is possible. The barrel is tight and finding bullet/sabot combinations that work is the biggest problem not accuracy.
