Here is what my primers from my reloads looked like from my trip to the range today:
Is this a sign of high pressure, or is it ok? I am using the starting load, so I wouldn't think it would be too high of pressure. |
| Primers indicating high pressure often have their edges flattened; this looks more like the pistol you fired them out of has an oversized firing pin hole in the breech, and some primer material is flowing into the gap... a little bit of this is normal, but that looks to be a bit more than I'm used to seeing. What is this starting load you are using? What kind of gun? |

Let me guess, Federal #100 primers? I would also guess that your CZ's firing pin hole is a bit on the large side. Your picture is exactly what Federal small pistol primers look like when shot out of my Ruger P95, regardless of how light the load was. My P95 has a large firing pin hole. The same primers in 3 of my other guns leave no such crater.
I now use CCI 500 for all of my 9mm loads. They don't crater, even in my Ruger. I'm guessing it has something to do w/ Federal primers being softer. |

What is this starting load you are using? What kind of gun? I'm kind of in agreement with the above. It doesn't look like any more cratering or primer flow than one would see with a striker fired gun like a Glock. Since the primer itself isn't flattened, I would say it looks okay. Have you tried any factory loads in your gun? If so, what do the primers look like on those? That's the comparison I would make first. |

Seems like an obvious comparison now. Thanks for the suggestion. |
