Rob Ski, I have a Wasr-10 after about the first 100 rounds each time I take it out to the property it begins to have soft primer strikes. I use mainly Tula but tried Winchester white box to see if it was the ammo I was using but still light primer strikes after 3 or 4 rounds. I then brushed and soaked my bolt in solvents for several minutes, took it out put 100 rounds through it, again started having light primer strikes. I figured it may be the firing pin but after examining the pin the flat back didn’t seem to mushroom or be warped in any way. I have only put about 3-4 thousand rounds through it and the gun was purchased new with matching # parts. Your feedback would be greatly appreciated. Love the YouTube channel too.
I just checked the head space borrowed some gauges from my buddy, and its all good. After looking at that I went back to the firing pin and it seems its a little deformed but nothing too major, so I went ahead and ordered a new FP.
