Checking Firing pins

[Calum]

A simple test of ones SKS firing pins.

With Safety on and muzzle in a safe direction.
Stripper clip loaded with 2 cartridges.

Load both cartridges.
Fire one.
Eject unfired Cartridge.
Prove Rifle Safe, and set in a secure place.

Compare the Primer on spent cartridge to the Live Cartridge.
Careful as things are prob' going to be rather hot.

One on the left was fired, and the one on the right was unfired.
As you can see the primers take quite a beating...something to consider if you reload this ammo someday, I'd suggest the CCI "Arsenal" primers as they are as tough as the originals.

Also if your Firing pin is put in Wrong (upside down in some Chinese versions), or is gummed up/doesn't rattle back and forth easily then the dent will be more pronounced in the unfired Cartridge. And sooner or later you are going to get a slam fire.

Edited to add...geepers I just realized I was 3 years old when this ammo was made.

Awesome I've gotta do this test with mine!! Y'know what else would be cool is if somone who's got on of those Murray's/Wolff firing pin return spring kits did this test, to show the difference between the OEM unsprung firing pin and the modded spring one. I'd pay to see that! Well, no I wouldn't, but it would be cool

As a sidenote, I just picked up 2 boxes of Federal 123gr SP hunting ammo, and I'm assuming they've got typical "soft" primers. Would a firing pin bounce like the one in Calum's pics be enough to set them off? I've used them before and never had a slamfire, but the odds are against me, so to speak And to think, I used to carry the damn thing around in the bush with just the safety on, a full mag and one up the pipe!!!

Hmmm where does one get one of these 'Murray's/Wolff firing pin return spring kits' in Canada?

And how much are they?

Your prob' still safe, as the firing pin has already done it's worst after it "love taps" the next round, and if you haven't pulled the trigger yet then the first round will have not been hit yet.
Mind you a long delayed "click bang" after the first shot would suck.

I wouldn't want to drop ones SKS with one ready to go in the chamber.
