RE: 300 Win Mag
LBRB, Do you really want to shoot loads put out by someone you've never met and know nothing about? Either buy a loading manual or two or go to some of the websites offered by bullet makers or powder manufacturers and start there. In any event, back off any single load or start with a lesser charge on published loads. Learn to tell if you have pressure problems. You also want to learn what shoots best in your rifle as well as what bullets work best for the shooting you do. A max. load may not be as accurate as a slightly slower load.
