Bipod group does look a little "ugly". I have a Duramax stock on my 12FV in .22-250. It groups better than that but typically I don't get as good of groups with a bipod as I do with a rest. Bipod doesn't allow the rifle to recoil normally by sliding in the pads. It hops causing what you see. Just my 2 pennies worth. Were it me I would do a little investigation. Something is slightly amiss.
