Delayed fire 20-30 seconds

If I have a misfire, I wait a full minute, and even that's not long enough if you believe the gunwriters. I have had hangfires before, but never a full minute later.
 
Hang fire is scary as hell. I'm glad I've never had one.
They can be a big problem.

That is why after a FTF, it is recommended to wait up to two minutes with the firearm pointing downrange, but most people go with about 30 seconds and call it a day.

They have taken longer before though.

God forbid that thing went off when you had just started to pull the slide or worse yet gone off when the muzzle was in an unsafe direction.

Your dad taught you well.
 
Like I said earlier, thank you all for posting. I have had several misfires over the years, some of which went off with a second strike, but thankfully none after clearing. There's always the first time, though...:eek:
 
About 1985 I was shooting my Walther PP. The Norma ammo I was using was only a couple of years old. I had a hangfire of 2 or 3 seconds. The next round never even made it out of the tube. The bullet was sticking half way out of the muzzle. I haven't used Norma since...
 
Can anyone explain exactly how it occurs?

I, too, am interested in just what happens to incur a hangfire (with metallic cartridges as opposed to black powder front-loaders). Anybody know?
 
In the military I was taught to wait a full minute if a cartridge would not go off. That was under range conditionss, of course.

I always heeded that with a rifle and had several slight hang fires with 8x57 IS surplus, just a one, or two seconds delay. That was at the most flinch control.

With a .303 I had one cartridge go off after at least 45 seconds, right after I had unlocked the action by turning the bolt, but not pulling it back.

I caught the recoil with my hand and it wasn't a hard push.
 
Hang fire should be a valid alibi. If it's not a valid alibi in your competion league, you should not be in that league.

In a self defense event, clear and fire. But not in a game! That's just dumb.
 
A hang fire can be caused by several things...

In military ammunition improper storage , heat humidity handling can cause the priming compound and the powder to deteriorate over time, leading to inconsistent ignition.

Wartime ammunition produced under pressure to get it into the hands of the troops, can lead to reduced quality control in the name of productivity. Smaller quantities of primer compound in the primer cup, excessive force when seating primers can lead to the shattering of the compound and causing it to gather at the lowest point when the rifle is shouldered. Thicker primer cups, light strikes from the firing pin.

Excessive vibration is not good for ammunition as it can cause the powder to change form, by rubbing against each individual grain with in the case or having the fine residue gather in the base of the case. this too can cause inconsistent performance.

Sometimes the priming compound itself is unstable and begins to chemically degrade and do so in a relatively short time, the chemicals used in powder production can if they begin to break down attack the priming compound, you also have outside contamination by moisture or oils during manufacture.

Then there is the case itself, deep primer pockets, smaller or deeper anvil in Berdan cases, off set flash holes.

Then you have the chance that it was an outright bad lot of ammunition that made it out into the market, due to the test lots drawn from within this particular batch being of sufficient quality to meet the minimum requirements.
 
A much appreciated and excellent list of causes for a hang-fire, Mueller, but I'm still curious as to what actually happens (or doesn't happen) in the "combustion" chamber at the time of retarded "ignition".
 
the simplest way to explain it from everyone i have asked is:

Range owner at my local range:

"its like a bad firecracker, it sits and smolders till it gets sufficient power to ignite the powder"

don't exactly know if that is true but makes sense to me.
