Hang fires

Can people with far far more knowledge me tell me what causes a hang fire.
My mate has just come back from his roar trip and he missed his trophy of a life time.
He was using remington corelock .308 and aimed on the stag at 10m and click nothing lowered the rifle and bang it went off when the butt hit his hip.
So the stag ran off and he managed to roar it back only to have the same thing happen again this te he pulled the trigger again and again them lowered the rifle only to have it go off again.

If factory ammo, old and wet or been wet at some point. If home loads, primer and powder incompatibility, or damp/contaminated. Bolt internals and or action dirty or faulty.

Ammo-related hang-fires are rare occurrences but do happen even with quality brands. It sounds as if the rifle needs to thoroughly checked by a gunsmith.

Yes^^^^
If you have hearded the fireing pin strick the primier and then there is a delay in the firing this is mostly down to the above.
If it dose not fire then it can be down to the rifle. (Which is not a hangfire)
When it happens it is hair raising:O_O:

Bought a MK 1 303 in 1981 and was given a heap of green coloured ex Boer war ammo, so it was already 80+ years old. It was click bang for most of it then. Velocity was way down and probably 4 seconds before ignition.

Had a few over the years but all with the 303 and old ammo, shot one deer once and that was a click bang but it did the job. Haven't had any with modern ammo or reloads and only a few misfires which didn't go at all.

Yes factory ammo and had been raining for 2 days.
I've had reloads go through the washing machine and no worries.
But my bet was moisture related

That could even be conditions for the firing pin to hydraulic.

I would try fresh factory ammo once rifle has been thoroughly cleaned.
If problem persists then its a fault with the rifle, and I would get it checked by a gunsmith.

Remington primers are known to be harder and less sensitive. Combine with a weak mainspring or corroded/gummed firing pin assembly maybe. There are a lot of things that can cause it.

when was bolt last stripped down n cleaned...assume its a bolt action????
bit of oil gets wet,turns to gunk..slows down firing pin....
had plenty of light strikes over the years with old tired hammer guns...cant recall it with bolt other than 303 brit.and new 22lr before bolt had been degreased.

He is a pig hunter so anything is possible.
I would have thought if it was water related causing a light primer strike that it wouldn't have fired at all.
His son ended up shooting his first sika stag the next day and had no problems.
So I'm thinking an ammo issue.

aaahh a "pig hunter" so rifle has probably been dragged through mud,blood and scrub for years....the internals might even look like photo Pengy put up a week ago....
I hunted with a chap down here...saw state of his rifle and came prepared next outing...grabbed his rifle off him,took ammo out and proceeded to clean it inside n out...then oiled the stock before handing it back...I HOPE he is suitably embarrassed enough to look after it in future,if he using a 30/30 MAYBE he didnt have lever up hard enough...or bolt not hard in...the BLR was a pig if rounds werent sized right down.... but 50 quid to knob of goat shit it will be dirty action at fault.

His rifle is not too bad it a winchester feather weight but even if the bolt is really full of shit how does it explain a delayed fireing.

buggered if I know...but cleaning bolt would be first point of order...close bolt,while still cocked set safety catch to middle position..remove from rifle ,now depress the wee lever/catchy thing on side and rotate bolt rear it will unscrew leaving spring under tension....to reassemble screw back in until catch thingy clicks back into place,put back in rifle and take safety off....

I had this issue with my model 70 when I tried to lighten the factory trigger, it would "hang fire" unpredictably some times 2 seconds sometimes 10 seconds.
I replaced the trigger with a timmney and the problem ceased....may help may not ?

I'm yet to look at the rifle but will be interesting to see what it is.

I take it you mean, lots of water in firing pin/spring compartment, causing rear of pin to stick like a suction cup and suddenly let go and fly forwards? Or just go forwards too slow.

Would be interesting to soak / assemble any bolt under water and see just how it works when totally water logged.

Strip and clean the bolt, how old is the ammo?

I'm going with crud in the bolt as well. My U/O was starting to do light strikes the other night with one barrel. Put the same round in next go and it would fire. Squirted a heap of brake kleen into the action if that doesn't work it will off to a smith.

No one has pointed out the danger of lowering your rifle if experiencing a misfire/hang fire. This could have easily ended up with a hole in the boot.
Important to maintain aim in a safe direction for a good period of time if a misfire or hang fire occurs even if the ultimate cause was as simple as failing to chamber a cartridge.

Yeah, I know it's hard in the heat of the moment and must admit I would probably would have quickly ejected the round and chambered another even though the deer had pissed off.......

Great point @zimmer safe direction for at least 10sec before unloading

Greetings Dannyb,
This is an often overlooked problem with a delayed fire. If someone has fiddled with the trigger and has not left enough overtravel so the sear can release cleanly the striker can hang up for a moment thus delaying the firing pin fall. The problem can vary with conditions. My bet would be this or a bolt full of crud. Modern ammunition will seldom give problems with hang fires if everything else is in order.
Regards Grandpamac.

a friend did that to his late 80's M70 243. Not hangfire, but the safety wouldnt engage. trigger was as light as. Cant remember if it passed my bump test i do after adjusting triggers but suspect it didnt

Never heard of a light pin strike cause hang fires, they usually go or don't in my experience but sounds like this has happened to others. Simply checking the cases will tell you. Damp powder would be my guess as it takes a while to get going.

That's what I was thinking he said the primers were hit well and I've also never seen a hang fire from a light primer strike.
