Barrel is free floating.
Are you saying that the the first shot is always 1.75 left and the 5th shot is always 1.75 right with the 3rd shot being spot on?
If so, you have evidence that barrel temperature is a strong component. The results of barrel heating is shifting bullet impact. The cause of this is usually a bedding problem.
To ensure the barrel is truly free floating is take a business card or 5 one dollar bills together and slide 'em from the front all the way to the action. It/they should flow easily, all the way.
After that, I'd check the mounting screws for proper torque.
If the above doesn't work out let us know there are a couple of other things to do.
