Greetings all. Glad to be new to the forum. At the range this morning and ran a few different kinds of ammo. Went to the CCI Stingers (which I've shot many times with no issues), and had a huge explosion in the action. I was rapid firing 3-5 shot strings. I noticed the muffled pop of a squib load but due to the rate of fire was not able to withhold a follow up round. BOOM! Huge blast in my face which was covered in powder residue. Step back and took a look. The extractor and extractor plunger were gone, somewhere in the grass. The bolt had come back and slammed forward about a half inch from being in battery, caught on a shredded case (looked like a peeled banana). Took a cleaning rod and the barrel is clear. Inspected the bore when I got home and I don't see any damage. So it seemed pretty clear what had happened. My question is this. Would a squib load be able to cycle the action? I've shot quiets and it obviously doesn't. I assume the squib load explosion would be much less powerful than the quiets. But it's obvious the bolt ejected the case and chambered the next round. Could it have fired out of battery? Is the 10/22 bolt capable of that? I'm questioning the whole experience, even wondering if I heard that distinct squib sound but I'm certain I did. Here's the kicker. My buddy has a 22LR Pistol . He grabs a new box of my Stingers and goes through a mag. Loads the next mag and there it is. Another squib. This time the bullet was lodged. I was watching and it wasn't that muffled pop. It just sounded like a slightly less powerful round. He would have fired into the squib load but felt a huge powder blast in his face. These boxes of 50 rounds I bought came in a brick of 10 boxes. I have no intention of using any more of the ammo. The fact it happened 2x tells me there was a bad batch of ammo that left the factory. I've talked to people that say that never happens but it's pretty clear it does. E-mailed CCI and the vendor I purchased it from so we'll see what they say. Apologize for this being so long and thanks so much for any input.
