The amount of powder to use in a reload is almost always related directly
to the WEIGHT of the bullet. BUT, different powders with the same weight
bullet will require different powder charges.
If you don't have one, get a good, RECENT reloading manual. Speer, Hornady,
Sierra, Hodgson, they all give good loading data. Study the data, decide
what powder and bullet you want to use, and start from there, using the
load charts in the book.
Reloading is really not that hard, if you follow the rules.
