Mine (280AI Professional) has been back to the factory twice now. This last trip they said they did a bedding job. Just got it back yesterday and thing still sucks. No consistency whatsoever. Best I could do was just under 2" groups at 100... some groups were 6"+. Very disappointed in the performance of this rifle. Looks and handles great, but it looks like I'm going to have to stick more money into this damn thing before it is of any use to us.
