Face full of powder from my Mosin

I was shooting some Hungarian light ball and Bulgarian heavy ball out of my well used Mosin Nagant this weekend, and on the last planned shot of the day with Hungarian ammo I got a face full of powder. Luckily I had shooting glasses on, so no eyeball damage. This is the first time this has ever happened to me. I have about 200 rounds through this gun total. The Hungarian ammo is steel cased. The Bulgarian is brass. After that happened, I picked up some shells from the ground and the Hungarian had more burnt powder on them than the Hungarian, but the Hungarain still had some. Is the gun worn out and a danger to shoot, or is the steel cased ammo possibly the culprit, not expanding and sealing as good or something like that? The case that caused the blowback was not ruptured or strange looking.

Thanks

You pierced a primer. The gun functioned in a way to protect you from further damage. The gun should be just fine, those things happen from time to time.

You might want to (because its easy to do) check your firing pin protrusion.

^+1. You definately should not have any problems with the steal cased ammo.

Good thing you had glasses on!!:D

Thanks, that is the best thing I could have heard. I didnt want to turn that into a parts gun. I was wondering how that much powder could come out of the front of the case, make a uturn, then still make it to my face! Pierced primer makes total sense. I wish I would have looked at the case closer.

Our local modern and vintage military matches make
safety glasses mandatory. Thanks for the reminder.
I will never complain again about having to carry and
use safety glasses.

Thats a good rule. I started always wearing safetly glasses a few years ago after a 22 bullet bounced off a steel plate from about 15 yards away and cut my forehead open. That would have hurt hitting my eye.

glad to hear your not hurt.

id check your pin protrusion. as suggested.

you can do this using the little metal tool that comes with most Mosins.

Screw the firing pin into the cocking knob until the back end is flush with the rear of the cocking knob and the slot lines up with the index mark. After fully assembling the bolt, decock it, make sure the bolt head is tight against the connector bar and check the firing pin protrusion with a gauge. The firing pin should touch the shallower (75) of the two center notches in the gauge and not touch the deeper (95) of the two center notches. If necessary, adjust by screwing the firing pin in or out of the cocking knob, always stopping with the index mark aligned.

If it happens again your firing pin may need adjustment. It is adjusted with the screw slot in middle of your cocking knob - look and see if witness marks are still lined up.

Attention: clean your bolt, inside and out. I have had 1 Hungarian round's primer pucture, and I also got a facefull. However, I forgot to clean the inside of the bolt and wound up with a very crunchy bolt-throw. Yes, the entire innards were rusted thick. Clean that bolt!!!

Pin length, headspace, or CRAP AMMO THAT IS ????? OLD is most
common spit in your face. Check in that order before using again!!!!!!!
