Re: A-4 McMillian stocks
While I agree that bedding is the way to go, before you do so, check a few things first.
Are the barrels touching the channel (free floated), does there appear to be any obvious play or binding between the barreled action and stock. When you installed the action screws did they screw in smooth or did you have to finesse them.
Of course bedding is better, and I have had all of my rifles bedded, but might as well try the easy fixes first.
