Misfire on Homeloads

I've had 1 or 2 over the last few years and have always left them in the chamber if it goes click. I always leave for a minute or two just incase, after finishing up my stalking or plinking I get it home and into the bullet puller straight away. No point in taking any unnecessary chances.
 
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.

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 ?
 
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.

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

Yes, quite safe.

Removing the unfired round too soon from the chamber is the awkward time, in case there's a 'Hang Fire' lurking waiting to go off.
Following a misfire, you should wait for a few minutes keeping the muzzle in a safe direction before extracting the round & reloading.

If a hang fire has occurred, extracting the defective round too soon, would in the case of a 'Hang Fire' being present I understand, be rather like having a grenade go off.
The misfired round should be left in the chamber to keep everything contained.
That's what I've read & believe anyway.

Personally, In thirty five years of reloading thousands of rounds, I've never experienced a hang fire and only a handful of misfires, all of which were Rem. 9 1/2 primers.
Those misfires occurred a few years ago and I still use Rem. 9 1/2 primers without further issue to date.

I've never at any time had any failures with CCI or Federal primers.
 
Interesting !
So my speed reloading as Buck stood there wasn't good ! Anyway all is well and will be trying cci or a few and if goes well will stick with them. Pity bought a thousand of the remi large primers tho.
 
Thankfully hang fires are extremely rare. Frankly i think you are more likely to come across a trigger or safety failure from someone fettling i.e goes bang on safety release, than a hang fire.
nevertheless the procedure for anything that clicks instead of booms is as finbear sets out. If anyone is with you let them know and maintain control of the rifle.
 
Oh dear !
I ran out of Federal small primers the other day and after a good rummage around managed to find some Remmy small primers so had an afternoon reloading a batch of .222 rounds.
I haven't tried them yet but after reading this and being quite some time since I used Remmy primers, I think the last time I used any was in the pistol days, am wondering whether I can expect an afternoon session of dismantling :-(

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?

they both look about right to my eyes, the unfired looks the same as any other misfired round I've ever seen that was not caused by mechanical failure of the firing pin etc. the fired primer will always have the flattened rather than 'stretched' look of the round that did not go off and did not therefore have the pressure to flatten off the primer.
 
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.

last time I fired a squib, (loaded with no powder by a tired and rushed, me) it went pop not bang and the primer alone was enough to drive the bullet into the rifling and needed the use of a cleaning rod from the muzzle to dislodge it with a few whacks.

and yet I and others have experienced them
 
Not true. You can over seat a primer. Been there, done it, had the ones that didn't go bang.
It doesn't just got the bottom, the edge of the primer rolls over and locks the anvil.

I wish I had photos to show some of the things that I see at the range. One being a box of factory ammo where two rounds dint let loose. After checking the rest it was noticed a couple with primers a little deeper. Put them in and tried firing, they did not fire. Tried and tried again but wouldn't fire. Nothing at all wrong inside the case, there was powder and a primer hole. How ever, the priemers was well dented, just the same as op photo.

I bet you the op loaded the round again and tried to fire it at least one more time.
 
Just because you haven't heard of it, doesn't not mean it doesn't happen. Just means you haven't experienced it.
