I usually load 38 Special +P but since accumulating a bunch of 357 cases, I thought I'd try my hand at those. However, most of the rounds have flattened primers which I think may be a sign of high pressure. In the attached pic, the left case is a factory round and the two right ones are my reloads. I did not use a particularly hot load (6.3 grains of Bullseye under a 158 grain JSP or 7.7 grains of Bullseye under 125 grain JSP) Both loads are at or under the starting points listed in the Lee Second edition manual. Case lengths between the fired factory round and my reloads are withing .001". Any ideas what's going on?
I'm using Winchester small pistol primers, BTW.
