If the throats in your Ruger have been opened to .452 and the bullets are .452, .453, or .454, the results will all be good and basically the same. I run bullets .002 over throat size all the time.
Only issue I can imagine encountering is maybe if the driving band was really far forward and it hung up in the throat when you loaded the gun.
