I have the same gun in .300 Win Mag, and it is one of the most accurate factory rifles I have ever owned. I too have the BOSS, but it shoots <1 MOA with factory Remington ammo, so I have never seen a need to mess with the BOSS. I am going to be trying handloading this year, so I may play with it some, but it is really not "necessary". Awesome gun and I would not hesitate to buy another one from that era. I cannot speak to the new ones being put out by FN. DanWell I have one in .30-06. It is a very consistent 3/4" to 1 1/2" shooter, depending on the load. It is a BOSS model, but I have never fiddled with the BOSS much. I assume I could get it dialed in more accurately with certain loads if I did. With standard cheap Federal 165s, it shoots 1" consistently. I can get it under 1" with handloaded Nosler 165 BTs. The fit, finish, and quality of this gun is top shelf.
