Highly dependent on alot of factors. Assuming book max is going to be the actual max in any rifle is not a good idea. All it takes is a chamber with tighter tolerances than a sloppy factory and some brass with a couple grains less capacity than the brass used for the book data and all of a sudden your grain over max is more like 5 grains over. Short of having proper pressure testing gear, Velocity is always going to be the best indicator of pressure.
