375 Cheytac brass question

[marzo2]

Hi

just would like to get your numbers of your bump gauge between your brand new brass and fired ones.

With my Whidden shoulder bump gauge (0.508):

brand new Peterson brass: 2.5345
Once fired: 2.543

basically my question is: Is that amount of strech normal?

thank you for your input

My Peterson brass averages 2.536 new and stretches to 2.546 after firing.

Yep sounds about right, no worries there.
