I think you can predict they'll shoot to point of aim when clean if you get one of the top quality aftermarket barrels. I predicted my 30 caliber Hart, Obermeyer and Kreiger barrels to do that; they all did. But with standard production factory barrels, I think most of them need a few shots to settle down.
My Anschutz .22 rimfire match barrels were predicted to shoot a few MOA high with a clean barrel; they did. Same with others using Hart, Lilja and Walther rimfire match barrels; they all shot high from a clean barrel. Takes 3 or 4 shots to get them fouled enough to slow the bullets down so they shot to point of aim.
