First for me. Primer came out after firing and got jammed in the internals so the safety selector wouldn't work. That gun was done for the day till I got home and ripped it apart to find out the issue.

might Want to drop your charge a couple grains

Factory ammo

Take a photo, contact the manufacturer and give them the serial number on the box. What brand of ammo?

Pretty sure it was Frontier

I would definitely be on the phone with the manufacturer.

Remanufactured ammo or new brass?

I once got a box of 410 that first round out stuck in the chamber of an NEF break open. It was definitely a stouter than normal pop and wouldn't extract. Had to drive it out with a cleaning rod. That box went back.

Contact them with an email do not mail any live ammo through the mail they don’t like that. The company will give you instructions.

Is it even worth my time? What would come out of emailing them?

May not be much for you but if a lot was produced wrong it may save someone else’s life.

I am having terrible luck with a batch of ammo from Freedom Munitions. It's 223 55gr FMJ reman.

Shooting last weekend a friend brought out two AR's with brand new Otter Creek suppressors. The jackets were coming off the bullets and hit damaged the end caps of his suppressors, as well as even damaging the flash hider as shown in the pictures above. Otter Creek has a lifetime warranty on their suppressors and they are repairing my friend's suppressors free of charge. They recommended to stay away from Freedom Munitions and AAC ammo.

Both suppressors were checked with a Geissele alignment rod before firing and were properly aligned.

Before this incident, I had been having many of these rounds blowing the primers out. You couldn't shoot 10 rounds without having a malfunction of the BCG getting jammed by a primer.

The picture of the cases with the primers starting to swell looking like a nipple was interesting. Usually the primer was just completely blown out. Necks of the cases are swelled much larger than the diameter of the bullets after firing as well.

In the pictures above you can see one instance where the primer actually stuck on the firing pin and stayed on the BCG.

Now the picture with the shavings on the table. I was shooting that day and started out with a clean gun and maybe 75 rounds in the gun started to occasionally not fire on the trigger pull. Then after maybe 20 more rounds the gun wouldn't fire at all. When I got home I pulled the BCG and when I removed the firing pin all of those metal shavings fell out from around the firing pin. There was more shavings than pictured that fell on the ground. What was happening was a piece of the primer was being sheared the size of the firing pin hole and falling inside the BCG around the firing pin. After enough primer pieces fell in there, the firing pin was lodged solid and couldn't move which is why the gun was no longer firing.

I'm in the email process now of relaying this information to Freedom, will see how they handle it.

Don't be cheap and try to save a few cents on ammo.

Bingo

Sound advice. Lots of customer complaints over the years for all sorts of ammo failures and lousy customer service.

Frontier by Hornady?

I think it is...... I never had the issue before. Might be one bad bullet. We'll see. I'm gonna try and shoot again next weekend before I make any decision.

Wear good shooting glasses!

Bad news for sure Bought some Winchester ammo back in the previous Trump administration I dont shoot my 6 mm much but had no problems for years One day using yhe same box as the previous year stuck bolt on my 788 cratered primer gave it a good scrubbing with jb bore cleaner it helped but still high pressure signs Emailed Winchester a couple times No response
Also bought a carton of 16 gauge dove and quail several years ago No issues with most of the carton tried to shoot off the last box and a half this summer one punctured primer one dented primer no ignition one stuck gun 3 for 3
I wonder if this comes from poor powder/primer storage during the dark years or new powders that change chemically over time

X2 on the Freedom ammo. A couple years ago I bought 500 rounds of 38 special from them for target shooting out of my 357's.
Had 3 squib loads out of the first 25 rounds that resulted in bullets stuck in the barrel and unburned powder in my face. I e-mailed them about it and they had me fill out a form
and questioned whether it was a faulty, substandard gun. It happened in both my Ruger GP100 and Colt Python. They ended up sending me a shipping label
to send the ammo back and reimbursed me for the unfired rounds. My local gunsmith told me he had seen a number of problems with Freedom ammo.

I bought a bulk bag of Winchester 300WSM brass when it first came out. There was a bad case in my bag. The headstamp was for a much smaller WSM cartridge. It had been sized to 300WSM. The smaller case was stretched to the point that there was no brass left for a case neck.

I sent it back to Winchester. Never got a thank you or any acknowledgement at all.
