I cracked open a case of our newer 62 gr gold dot service ammo - we're swapping from the 55 gr gold dot because where we got it, the heavier round was a little less expensive, and what I've read says it penetrates a little deeper in gel.
So, I fired maybe the first half of the case over the last few weeks with no issues. Somewhere in the middle of a mag, click and no bang, Weird. Tap, rack, back to work. Looked at the round, and the primer got a good, deep smack. Put it back in the mag, and tried again - nothing.
I can't remember the last time I had a round from anything not fire. This is like a Bigfoot sighting or finding a land shark. Doesn't give me a warm fuzzy. This might just be a numbers game - I was due to see one eventually - but if anyone has had similar problems I'd like to know if it's a thing. I can't have our duty ammo not firing when needed. On a scale of one to bad, it would be closer to bad.
Checked firing pin protrusion, and it was fine. No other problems with the rifle, mags or ammo. No pics, but the firing pin was hit well and good.
