And I am one of those, though I have worked up loads for both. My older accurate data lists CCI 500 for #2 through #9.Most reloaders don't even use a magnum primer with AA#9.
9.7gr of #7 is light load for this bullet, I'd like see better than 89 fps for the ES. I have 9.2 and 9.5gr with CCI 550 loaded for testing.
As you known mag. primers can be of benefit where standard primers are the norm
