Please don't take this the wrong way, but.
You could save yourself some aggravation and frustration if you would follow the advice given above and understand one important thing about handloading.
Load data is Not a recipe and should not be treated as such. It is merely a guideline as there are to many variables to be considered a recipe.
That said, it is perfectly safe and acceptable to use tested data of same weight bullets of similar construction by different manufacturers. If you are loading a Hornady 50gr V-Max bullet and Hodgdon lists a 50gr Speer SP, go ahead and use that data it will be fine as long as you, Start low and work up. Even if Hodgdon data used the V-Max you should still, Start low and work up.
Same goes for different brass and primers.
