I admittedly have not read all of th posts here, but you do realize you can simply acquire a pre-fit replacement barrel for your rifle in Super match grade. It will require a gunsmith to take off the old one but all he has to do is headspace the new one, but it will not be an arm and a leg. We're not talking a full install at all. You will end up with a superb accurate rifle when yo are done. $800 will put you into a rifle with a faster twist, but not neccessarily a more accure rifle. I would MUCH rather have an accurate rifle that shot light bullets than an inaccurate one that shoots heavies. You can always learn to steer an accurate gun. You can never learn to steer an inaccurate gun.
