Are we talking high pressure rounds or moderate pressure rounds?

Tap the base of each cartridge and then feel and see if any primers have protruded. If not, I would go forward with loading and firing the cartridges. In the future I would set aside anyone that feels loose in a separate bin to evaluate later.

Just something to ease your worries. Think about all those who load on a progressive press and miss loose primers (as one cannot feel them like a hand primer), myself included.

2 rounds I’ve never fired .223 and 5.7
 
If you find a batch of brass with blown primer pockets it’s just easier to toss them and avoid the headaches. I had a bunch I threw out, then there were a few I thought might work. A 24 lb recoil spring popped one out when the round chambered and tied up the gun. Never again..
 
My hot 260s start getting loose around the 9th reload, long before the third case trim. When I get to 20% of a case lot with no effort to prime, the lot gets deprimed and scrapped. I've experienced flame cutting on the bolt face of an AR-15 with factory ammo. Fortunately, no gas in my face yet. If you have any doubts, just scrap it.
 
I seat primers indivually , I don't combine it with any other operation . if I feel one that's too easy to seat I put a sharpie mark on it and toss it after its fired. It's all preference but if the primer seats with no effort , it's time to toss the brass . some, like 357 mag pmc cases are very easy to seat on their first reload and stay that way. Others like s&b take some effort and seem to stay that way.

I stopped cleaning primer pockets with the little brush twisty thing, I figure it's better to have a little crud in there to maybe offer a little extra resistance . hasn't been an issue . this is likely a more common issue with rifle cases and I don't do much of that so I don't have superior insight into the really stretched out pockets, for handguns I think the case will split usually before the pocket is too loose.

I was thinking about tapping it on wood and see if it falls out. Didn’t know the physics behind primer pockets

I had some rattle loose in the hard case. I was on a hunting trip with my wife. So I dabbed some nail polish on after reinserting them. The entire lot was rejected after that trip.
Rifle was a bolt gun. So residual pressure wasn't an issue.
 
Are we talking about rifle, pistol or both? I just haven’t experienced anything extreme like some are describing. And, how many times have these cases been reloaded?

I get easier vs. tighter, sure, but it occurs with a brand of primer (CCI always tighter than Winchester) or particular headstamp.

This sounds like my experience and views.

What type of firearm? What do you mean tied up the gun? How does a recoil spring pop out?

it was a RIA 10mm. When the slide chambered the round the energy of the recoil spring was strong enough to pop the primer out. The round didn’t go off and the extractor didn’t catch the round when I cycled the slide. But the next round in the magazine tried to feed. Double jam.

Guess you all know this is one of two threads ongoing for same topic, but several different players. I just realized it—up to late.

Topic has been talked to death, burial, and resurrection. Lots of great info though.

thanks! I didn’t realize there was another thread. I’m not to reloading but new-ish to bottle neck rounds.
