I have Federal and CCI mainly but have been using my few Remington primers up. And lots of people were saying during the shortage to substitute magnum for regular with no issues which i DID NOT. Or am i just ignorant? (Yes I know how the other parts of the cartridge can.)
Thanks & much appreciation for the answers.

I keep a part of a page from a reloading magazine where they posted pressure measured from different primers. I have it taped to the inside of my self built primer magazine box. I tried to post the picture but this website needs the picture to be exceptionally small so I'll just give the fun parts here. 45 colt +P 310gr Keith cast Enforcer 21.0gr WLP 22,490 psi, and CCI#350 35,950 psi. Wow, that is a delta of 13,460 psi right there!
