Strange misfire
I was RCO for one of my clubs at the weekend. One of the shooters had a round that didn't go off. When he extracted it, the case came out with a fired primer and the bullet was stuck in the lands.
The strange part about it was that the case was still full of powder.
I've never seen this before. Anyone?

Re: Strange misfire
Yes but I could not explain it either.
Suspect powder or contam powder?

blocked flash hole ?
primer cleared it and pressurised case enough to push bullet out, but in clearing didn't have enough left to ignite powder.

Re: Strange misfire
+1.
The primer must have supplied sufficient energy to propel the bullet into the rifling, but the main charge didn't ignite for some reason.
Did anybody try to light a sample of the charge with a match/lighter to see if it burned OK?

Yes, as an RCO I have seen a few of these over the years. Have stopped twice now shooters racking another one in too which would be catastrophic.
Could be contaminated powder. Oil can do this quite effectively.
Re: Strange misfire
Degraded or compromised powder. Used to see this a lot when old fellas were still loading their Enfiekds with rusty tins of ICI propellants that they had kept in the shed for 30 years. Basically a partial ignition.
In 1978 I was told by my grand dad that the secret to rifle accuracy is, a quality bullet, fired down a quality barrel..... How has that changed?

Re: Strange misfire
To be fair that does make sense. Primers are pretty pokey and if they don't get powder to go there is probably something wrong with it. Lionel once kindly gave me a miss fired .50 for my collection. It was that wet internally the powder was all caked.Sim G wrote:Degraded or compromised powder.

Re: Strange misfire
I had this with some 9mm ammo that had been poorly stored. The powder granules had lost their shape when i pulled the bullets and the powder smelled 'foisty'. It still burned when i tried it though. In fact far more efficiently than i expected and i got 3" wide 3' high column of blue/green flame right in the face

Re: Strange misfire
Thanks everyone. I'll pass those thoughts on the the shooter (he was using reloads).
No we didn't think to try lighting the powder.

Did you not do genies when you were a kid (and still do). You weren't a proper kid in Sunderland around november time if you still had your full compliment of eyebrows......Blackstuff wrote:I had this with some 9mm ammo that had been poorly stored.
