Flash Hole Size

[4D5auto]

It appears I have some pistol brass with a slightly larger flash hole. Curiosity has got to me about using standard and magnum primers with this brass, to the point if there may be any ramifications in doing so. I have used magnum primers in other pistol calibers before, but all with standard size FH. So, my main concern now is with 9mm brass using either primers.
