Extreme Spread?

What can be done to lower Extreme spread when reloading bullets? I took out my 300 win Mag and found that it had an ES of almost 100 FPS. I understand that this may be a very open question, but it is the only way that I know how to ask it. Thanks

    I am at work and not able to get to my notes for the COAL. I did work with it and found that the length that sierra suggested yielded the best groups though. So I loaded them at that length.
