underloaded
You are from 5 to 9 grains under max,(depending on which manual you look at). Given that fact, your powder position is one reason for higher SD #'s and larger group size. Most rifles like a higher percentage of capacity powder charge,(above 95%). It can't be out of position in relation to the primer flame. At 60.0 grains, you are close to 10% under max. You should NOT go UNDER that!
You should be able to get to, or real close to, 3000 fps with the 300 WSM. I can easily get there with numerous loads in my 23 inch Browning a-bolt.
