1hole,The reason that they put that warning in the instructions is because the Federal primers have a problem going off while you are pressing them into the primer pockets.
I have had this happen before,and will not use Federal primers for any of my reloading.
It happened many years ago when I was in my twenty's,and I thought I knew everything.It scared the crap out of me,and also taught me a valuable lesson.
Read the damn instructions,and I don't know everything!
