Many component manufactures build there own "Recipe" book for their bullets, like Hornady, Speer, Nozler etc.
These manuals list their test equipment like Bart point's out.
Your equipment may not be just like theirs and that is why we all start a load that is at a low end of the recipe and test fire watching for signs of High Pressure, and of course how well they group.
If we try out a new fangled bullet that is of a different weight and shape and it's not in our manual we may look in another and find one very close. Then starting at a low end and work up.
There are also resources here on the web and that is good but your good manual's are just so important for reference. So is this Forum!
