Working up a load of 45 ACP today and I had several primer failures. CCI 300's in mixed brass, all of them had solid strikes but didn't ignite.
My initial thought was I had moisture in the brass from wet tumbling... the rounds that didn't ignite had no signs of powder clumping when pulled down. The brass I'm using is a mix of Fiocchi USA and Winchester, I guess they could be crimped but the primers seated easy enough with a hand primer. This is my first time using large primers, I've never had a failure with small pistol or rifle. Thoughts? |

Something simple to check- make sure you are using large pistol primers and not large rifle primers. I wish manufacturers would change the color of their packaging between rifle and pistol primers. It really is an easy thing to switch. |

It really is an easy thing to switch. They're large pistol, I don't have any large rifle on hand. I've shot thousands of CCI 500 - small pistol and I've never had a primer failure. Given that track record I went with the CCI 300 for my 45 offering. |

Given that track record I went with the CCI 300 for my 45 offering. So much for an easy answer. I have not had any problems with CCI large pistol primers over the years. The only problem I have had with .45ACP loads was when I reloaded the cases past the point I should have- loose primer pockets. |

Quoted: Ran them through a Sig P220, the trigger was pulled multiple times, they didn't go off. Quoted: Quoted: Did you try shooting them again to see if they lit the second time? That usually means they weren't seated fully. Ran them through a Sig P220, the trigger was pulled multiple times, they didn't go off. I'm thinking bad primers then, if you don't think there was moisture issues. |

Time will tell, I went back and baked all the brass to be sure. I can't tell if the primer pockets on the Fiocchi USA brass are crimped or not. If they were crimped would I be able to seat a primers without crushing / denting them? I know I was able to when I reloaded 223 with WSR primers but they had a relatively small diameter. I did have one primer seated in a Winchester case that made a "POP", I thought it squibbed but it didn't. The bullet didn't appear to move in the case but what little powder ignited blew past the bullet which I can't fathom considering that these have a ton of neck tension. |

Fiocchi brass isn't crimped, but both it and Winchester have tight primer pockets which is why my first guess was primers not seated all the way. |

You can check primer function without a complete load. No powder or projectile Proper firearms safety precautions and safety gear applies. Seat primers into cases. Chamber into firearm Point to a safe direction ( Perform this in a secure environment ) and pull trigger. If primers are good they should go off. And Have you checked for gunk in the firing pin channel? The appearance of the primer hit should indicate if there is an obstruction and shortening the stroke. Not a typical scenario but its possible to get a piece of brass in there and carbon buildup can cause it. It's easy enough to do. |

It looks like the compound is still un-burnt so you definitely had some sort of primer failure. Motor I had Winchester sell me a cup and anvil with no mix in the cup... walked it across street when ATA was Dayton, headed straight to the Winchester building, fella put it in an evidence type envelope, took my info, and took it back to Winchester with him.. got coupon for $25,,, wasn't enough to cover 1000 primer,, couple dollar short... Dead primer in middle of steel run.. I saved cartridge and took it apart when I got home, because I am cheap.... |

OP Assume you are not using any case lube, but carbide sizer dies. There could have been residual water in the primer pocket that might not be inside the case.
I would set up a test run of 10-20 primed cases with no charge or bullet. Just use cases that have not been exposed to water. If you don't get any failures, more than likely it was your process. If you get failures, call the manufacturer. (On any failures, try twice to load and fire.) As stated previously, the noise will be loud and point in a safe direction. |
