OK, now let me share my two cents.
It is hard to rate primers finally in their interaction.
Different powders have different burning needs, and some shotshell
primers may have more bursting power (brisance) but less of a swirl in the hot embers emission.
So a primer that is rated hotter with one type of powder may have to be rated colder with another type of powder.
My 2 cents.
Mike

P.S.
Brisance is the shattering capability of a high explosive, determined mainly by its detonation pressure. The term can be traced from the French verb "briser" (to break or shatter) ultimately derived from the Celtic word "brissim" (to break).

Remember, priming compound is an explosive and not a propellant.
