Now that I typed all that out for you I strongly suggest that you purchase a reloading manual this is to much typing and double checking. It is a good idea anyway to have reloading manuals available if your getting into reloading. I have a reloading manual from almost every manufacture.
For the 300 grain Sierra I would suggest starting at 100 grains of H1000 and working up.
