Misfire?

[djmike]

Still being a new to reloading for less than year I have a question about a possible misfire. I loaded 9mm 124gr with Titegroup and cci 500 primers. The brass is once fired federal brass. Once fired by me. Out of the last batch of 300 I had 2 that the firing pin hit but never discharged. I can see the dimple but no bang! The primers were seated flush and looked like all the others, I have loaded over 2000 the same way and never had a fail. I had one in a Glock 17 and 1 in a Sig p226 so I cant say its the gun. Is this normal or maybe just a bad batch of primers if possible?
Just trying to figure out what happened for my own knowledge..

in 30-ish years of reloading and using CCI and Win primers, I have yet to have one not go bang. So my guess is you need to seat those primers deeper, until you feel them bottoming out completely. Flush is not the correct standard, I seat at least .004" below the case head or until I feel them positively bottoming out. I've had some pockets that required me to go as deep as .008" below the case head. In fact, you can't really use a visual standard as your guide, you need to feel it seating to full contact with the bottom of the pocket.

When this happens to me I will make one or two more attempts to fire the round. If you primer was just a bit high the first strike just finished seating the primer in the pocket. Sometimes the second strike will compress the compound between the cup and the anvil and the round fires.

If after the second or third strike the primer still does not go bang you most probably have a bad primer. Sometimes a striker fired weapon produces a "light strike", that is lighter than a hammer struck firing pin and may magnify ignition issues.

I hav'nt been loading quite that long I've yet to have one not go bang also

If a primmers bad. You will have more than one "Not go bang" IMO, It would be a bad batch of primmers.. But there is always a first time for everything ; )

Most likely the two primers were not fully seated. Did you try shooting them a second time?

Only ones I've had not go off have been Tula primers but that only 2-4 out of a thousand. Most of the time they go bang on second attempt

The primer cup has to be seated below flush so it is in contact with the bottom of the primer posket.

That pre-loads the primer anvil into the primer compound so they will go bang every time.

If you are priming to seat flush?

You are very likely not fully seating the primers.

The only other possibility is contamination and I rather doubt it. I have primers roll around on the floor, gather lint, and even get slimy and they still go bang. Seat them solidly.

I am going to try and fire them again tomorrow and see what happens. Hopefully the go bang and its just a seating issue.
