No. You will go broke. take a bullet and load it with whatever appropriate powder you have chosen. work the load, from bottom to the top in 1gr increments.
There is a little bit of fudging that can be done. sometimes its the length of the bullet, sometimes its the powder charge, sometimes its a powder primer combination that will make the difference.
Powder isn't cheap. buy a pound, see what comes of it. if you get good results, tweak your loads to get better results. If everything about it was terrible, then switch powder.
Get a notebook. record everything you do. If you are new to reloading, there may be something you discover in the next few months you will want to look back on in a few years. There are many other valid and worthy reasons to have a log book.
welcome to reloading!
