SKS fail to fire
« on: January 22, 2022, 05:06:35 PM »
Hello everyone, I need help with a SKS that will not fire.
The rifle is a Norinco SKS standard. After it failed to fire two years ago I disassembled it, cleaned it, cleaned the bolt.
The firing pin does the rattle some people say we like to hear.
I put no oil in bolt. Firing pin looks good. It still will not fire Hornady brass case ammo.
Years ago it used to shoot steel case ammo very well with no fail to fire.
I broke it down again recently. Still a fail to fire.
I received a new hammer spring today. Could this be the problem?
It is a surplus never issued spring off ebay.
I'm attaching two photos because not having fired the gun lately, I cannot remember if the cartridges goes all the way in the bore, it leaves about two to three eights out of the bore. Is this as far as the cartridge is supposed to go into the bore?
Thank you. -Stang94

Dented primer on the ones that did not fire?
Is that sand?
and a strange looking primer?

Here's one of mine.
Once fired case, not resized.

Thanks Rocket, it looks like from your photo that my cartridge is seated correctly in the bore.
The round I have in the photo is a Snap Cap round.
Here is a photo of the fail to fire round.
I would not even call this a light strike.
What are your thoughts on the hammer spring replacement?
Thanks. -Stang94

Light makes it look light to me.
How about an angled/shadow pic of the primer hit?

Brass should be easier to fire.
You have the hammer spring, why not try it.
I hesitate to suggest this, but a primed EMPTY case might show something. 
Point in a safe direction. 
Head space check (in the back of the bolt where it drops down) and measure firing pin protrusion (with a picture of the pin protruding).
A few different ways to remove the hammer.  Here's how I do it.

Could the firing pin have broke a piece off?

I installed the new hammer spring back into the rifle.
I loaded it with a dead round with a rubber snap cap that sits where the primer does.
It does now leave a small ring on the rubber from the firing pin.
I guess I'll just have to test it one day when the neighborhood is less occupied.
Does a ring on the rubber fake primer indicate a fire? Thanks - Stang94

I glued some aluminum pie tin to where the primer goes in a spent shell.
I dry fired it and here is what it did to the pie tin.
