I have a Black Diamond XR that as you know is a free floated barrel. The dollar bill test is easy with that rifle and without a doubt it is a great shooter. Whether you would gain a lot of accuracy by floating the barrel is unknown. The design of the Omega is not mean to be a floater. Now bedding the rifle could not hurt it, and should actually make the rifle even more stable. If you have a friend that is skilled in bedding a rifle, I would probably go that route since you seem unhappy with a 2" group at 100 yards (that some people only dream of).
