You will learn more about your rifle by making workup loads starting at the suggested starting load and working up.
There are just too many variations in firearms and reloading components to answer your question.
Example, the variations in .223/5.56 case capacity can cause 6,000 psi difference in chamber pressure.
And a accurate load I worked up in my .308 Savage Hog Hunter could be far different in your rifle.
