Changing primers can change results in different rifles with different chamberings and different loads.
A generalization is inaccurate advise.
Sometimes you see a change and sometimes you don't.
I have a 7x57 that hates CC! 200's and a .30/06 that loves them. You can't guess, you have to try them and see how the results average out.
Both like Federal 210's but I only knew that after checking.
