yesQuick question is a misfired round safe to handle also is it safe to put in a bullet puller hammer ?? Always wondered ?

funnily enough I had a dud CCI primer last month! I agree with the other statements as far as the indents are deep enough, and the primers are not seated too deeply, I still wonder if the primeers weren't seated deep enough, or if the round wasn't fully seated in the chamber ?Look at the picture of the indents in the primers. They are adequate to set a good primer off. No question of incorrect seating at all. I suspect faulty or damp primers due to poor storage either prior to seating or as loaded rounds.
Get some CCI primers, I have never had a dud yet.
nice to see correct use of the term head in relation to ammunition. CORRECT TERMINOLOGY MATTERS!![]()
Primers being seated to deep. If I remember rightly the rem primer cup it the shallowest of the large rifle primers. I have had the same problem a while back. It was the Lee auto primer and I can't remember the primer off hand.
When you seat to deep you roll the top of the primer cup over and into the anvil. Can't remember where I was reading it but never had the problem since.
£4 test. Either murom or CCI . Load 20 but don't seat the primers to deep. As long as they sit just below the head then you'll be good to go.

I find it hard to tell from the pic just how deep the dents are, but they look about the same.
Is it right to think that the dent in a fired primer might be shallower after firing than it was at the moment when the striker set it off, because of the pressure of discharge? In which case, if they both look the same, then the one that failed to go off might indeed be a light strike?
How can you seat a primer "too deep"? Are your primer pockets deeper than standard? If not, they will stop when they hit the bottom of the primer pocket and hence be correctly seated.

I suppose the idea is that the primers could be "too shallow". If, for some reason, some of the primers are too shallow (e.g. manufacturing defect), then when they hit the bottom of the primer pocket they could be too deep?
Well, I for one never heard of such a thing. Federal used to say that their failure rate (failure to go bang rate) was less than one in a million.
FWIW, the OP's misfire looked to me like a squib, i.e. no powder in the cartridge. The primer fires but it's insifficient to move the bullet out of the case. It can happen. I did it once. Primer defect? Very much less likely: so unlikely to the point that I would dismiss it as a possible cause.
