Thanks,Fellows,for taking time to reply.
I can't understand why they would intentionally put that cut in there.
What does "shaving some of the primer flow" mean.
With a high-intensity round like the .40,I would be concerned about primer perforations,especially with soft primers like Federals.
I have over 4000 rounds of once-fired .40 S&W empty brass,that were fired in many handguns,and none show a primer defect even 25% of the size of these.
