I've always felt Nosler velocities ran a little high for the amount of powder called for in their loads.I trust my chronograph and don't worry too much what the book says.It's only a guide,every rifle is different and powders can vary from lot to lot too.

As Bob Hagel would say"You should not use a rifle that will kill an animal when everything goes right; you should use one that will do the job when everything goes wrong."Good words of wisdom...............
