I believe I paid $75 for a re-crowning of one of my rifles at Duffys Gun Room. As Jake said --- Look at a recently fired muzzle of a gun. It should display an even radius of sharp spear looking carbon deposits around the muzzle crown. If the radius is uneven...you need a re-crown.
A hot barrel and receiver generated, from multiple rounds fired...will have a tendency to spread the groups wider.
There is a stock action bolt torque tightening sequence for two action bolts on a rifle.
Tap the buttstock perpendicular on a carpeted floor to probably set the receiver in the stock. For the torque bolt tightening sequence and poundage might be variable, but I'm guessing that it is the bolt closest to the receiver that you tighten first.
Maybe someone else can explain that better....
This might help some:
