I would NOT use final finsh in a new Service rifle. I would shoot and clean with 5 single rounds followed by a single 3 round group (slow fire) and clean followed by a single 5 round group, (slow fire) clean and call it good.
Your RRA NM has a Wilson match barrel which could take you to Master or beyond. Feed it good ammo and if it's not hitting the ten ring, either your sights are off or it's the nut behind the trigger.
Where I would use Tubbs final finsh is when the throat is rough and the rifle is making tons of copper.
