blown primer and firing pin

[domxyz]

Shooting Norinco out of a weatherby vanguard. After about 5 rounds notice a blown primer on one of the case and gun starts to fail to strike on 80% of the shots. Light strike on 15% not enough to ignite and fire only 5% of the time.
Can a blown primer completely mess up my firing pin. Can it be adjusted simply. Its not broken. Rifle doesn't fire better quality ammo and norinco ammo fires in another rifle 99%

Are you firing milsurp 762 Nato in a 308 win?

Could have gummed up the firing pin and spring with shards of primer.....disassemble bolt, clean , inspect or trip to gunsmith....

I've seen this before. Cleaned the pin channel, pin and spring and I was off to the races again.

That is a bad idea you can shoot .223 in a 5.56 chamber but not the other way around it causes unsafe conditions they are not identical contrary to popular belief the 5.56 has a thicker case and runs at higher pressure if i recall correctly
