Mine has barrel band and is not free floated...and either of those factors could change POI’s as the barrel heats. And of course there is always the possibility that the barrel was not properly stress relieved. Nothing you can do about those things.
Best bet is the bore cleaning. I would also wash out the bolt and raceways with WD-40 to make sure there is no crud. The bolt rotates to lock which is not nearly as tight as bolt action so keep it clean.
