Me and my buddy went and shot his .300 blackout (suppressed) today and had 1 in 10 failure to feeds, because of primers blowing out of the casing back into and jamming the rifle. The last one causing the rifle to be jammed to where you couldn’t cycle the bolt (even while mortaring it) or remove the lower because the bolt was locked and partially extending into the buffer tube.

I’m guessing you can’t send the ammo back since it’s reman?

Anyone else experienced primers just shooting back into the rifle?

Purchased from 2A warehouse.

how many times had that brass been fired and what were the prior loads.
 
Yes. That happens to me sometimes with my handloads because I run the brass to failure (whenever that might be). That is either worn out primer pockets from being fired too many times, significant overpressure from the loads being way too hot, or too much primer pocket reaming when removing the primer pocket crimp resulting in not enough material holding the primer in place. Either way that's no good, and obviously makes the ammo unreliable, if not dangerous if overpressure is the reason.

That’s exactly my point with reman, you don’t know what that brass went through.

Exactly. 2A Warehouse probably just sourced their brass from "wherever," and thus they have no way to vet the brass. They probably just took the brass, processed it and hoped for the best. I would do tests to make sure the ammo isn't overpressure, and as long as it wasn't unsafe, I would relegate it to just range/practice ammo, with the understanding that that's a bad batch of brass. I definitely wouldn't use it for self-defense or competition ammo. Reman's one of those things where "ya rollz yer dice 'n ya takez yer chances." That's why it's cheaper.

No clue how many times it was used. I’ve only bought reman 9mm that claimed it was only once fired.

Multiple head stamps.

Did you by chance take a look at the head stamps on the brass with the blown primers?

I would bet the primers that fell out were because the primer pockets were over swaged/reamed converted 556/223 brass

Bingo! That’s what I was thinking too.
 
It’s easy to ruin a primer pocket with a swaging tool or reamer. I destroyed 100 good federal .223 brass once like that. No go gauge wouldn’t go but the go gauge was loose as could be. I set up the first one and went to town.
 
I know someone that had factory 300 BO ammo that the primers would do that in his rifle, and not someone else's rifle. We never figured out exactly why. The only thing we could figure was that his gun may have been over-gassed.
 
Just like new production, reman will vary in quality between manufacturers. I've been shooting Freedom Munitions reman in 223 and 9mm for years with no issue. Haven't tried their 300BLK because I reload that myself.

Up until Dec 28, 2023, all their reviews were 4 or 5 stars, and even then there are only 3 "bad" reviews. I did notice that a lot of the reviews said they looked good but had not fired any.

Thanks for the input. Reman = trash.

Not all remanufactured ammo is created the same and definitely not all trash.
 
Years ago (10+) and before I got into reloading, I bought some NEW (not reman) 9mm from Freedom Munitions. XTP bullets. I had multiple rounds that the primers fell out of, one of them during cycling BEFORE it was fired. I forget the headstamp of the brass, but they were those stupid internally-stepped cases. I only shot a few boxes of them, still have the rest somewhere. One day I will pull all the bullets from them and trash the brass.

ON EDIT:
Before that purchase, I shot a LOT of the FM reman ammo and had no problems whatsoever. I did not contact them regarding this batch - they probably would have replaced it, I just didn't want to go to the trouble at the time.

There was some 556 going around a few years ago that was doing this. Primers in triggers.

I think it was Independence. @Climberman didn't this happen to you once?
 
Think of the tolerances that are involved. Friction fit, from tight to falling out is very, very small. It's amazing to me, that it works at all in the kind of mass production we're talking about.
 
Did You find any unfired cartridges with loose primers? I've had them fall out in the ammo box when I botched swaging brass.

I just don't see a primer falling out into the works just because of how the bolt is designed. The case is still in the barrel and the shell base is still in the bolt (extractor holding it in).
Maybe a previously popped primer?

I've only had one jam from debris. A chunk or rim broke off and wedged under the trigger. Could not fire until the piece was removed to let the trigger thingy toggle and release the sear.

Only other jams I've actually seen involved complete cases going where they shouldn't.

It was definitely from a previously shot round, I’m guessing popping out upon ejection of the spent casing. The eventually extracted brass still had the primer.

The other “jams” were really just failure to feeds, because the primer worked its way into the barrel extension, preventing the bolt from seating completely.

It was IMI ammo and it was new factory ammo. I contacted them and they replaced it with new ammo.

I think the IMI either had loose pockets or was too hot but I had primers everywhere in my rifle after a class I took. Lots of jams.

If I were you @barf , I would contact the company and complain. Give them an opportunity to make it right. Reman or not, it should not be blowing primers like that.

It was @Mike86 ammo. He said he got it like a year ago but is still gonna reach out and see what they say.

Thanks everyone!
 
I had some IMI 5.56 once that would blow primers in a .223 Wylde chamber consistently and sometimes in a 5.56 chamber. If I recall it was loaded real hot. I reloaded the brass and when decapping didn’t notice any primers being loose. It was just too hot.
