You said this is for rifle re-loading, you don't say what you are loading it for.
Are you hunting or long range target shooting. Different bullets so different reasoning.
If you are long range target shooting I would put #4 at #2 of the list.
If you are hunting @ 200yds or less, it can go further down the list.
#1 would be case length and case re-sized to fit my chamber,#2 bullet weight, (their almost lateral), then powder charge consistency, Primer, and then the rest.
Your #3 isn't in my equation. It's already a given to use all the same primers for the same batch no-matter what reason your reloading for.
