Depending on the primer, you can start seeing cratering at 50,000psi with the softer, thinner cups, whereas the thicker, stronger cups might not show any signs until they hit 70,000psi, and they might be ever so subtle.
What did your chronograph give you for ES and SD? How many shots?
I ran six shots thru the Chrony at 2922, 2888, 2889, 2909 ,2930, 2921.
