Er, RFutch is gonna send the rifle to Hornady? If he removes the case, Hornady will probably not pay him for a new rifle? Why would he take a factory brass case out of a damaged rifle?

I just want my rifle back in the condition it was before the incident. Hopefully, not on my dime. |

Once you remove the bolt/case, Hornady could more easily deny the warranty claim. |

Subscribing to this since I have 5 unopened boxes from the same lot sitting on my shelf.

I would be concerned about the integrity of the front pivot lugs on the lower receiver. These lugs carry a lot of load when the rear pivot pin is pulled (for cleaning, etc).
If they have been stressed, their fatigue life has been reduced they could fail (crack) prematurely. Notice the upper is badly damaged right in their vicinity. If they fail sometime in the future (they may not fail right away), your lower receiver is "toast". If they determine the event was due to faulty ammunition (as opposed to a rifle malfunction), I would want them to replace the entire rifle, including the barrel which you mentioned as being "okay". Your optics and mounts should be unaffected. P.S. - When shooting prone, the only thing between your eyes and the hot gasses is the charging handle. These leak even during normal firing, during a KABOOM!,... I'm glad you ordered some eye protection that you like and will wear. If the temple pieces interfere with your muffs, wear foam plugs inside the muffs. |

Don't proof loads/blue pills usually have a steel case?
I don't think you can double charge a 223 case. The load density is just too high. Glad you are OK, and thanks for the reminder that eye protection is mandatory. I sometimes let my kids get away with not using it, becuase they are always 'borrowing' the shooting glasses in my range bag for airsoft and I don't realize it until we get to the range. |

Probably because he has it set up as a precision rifle and Hornady steel case match ammo, while not top of the line, is not just blasting ammo and more likely to be used by shooters in this community than any other...

I see no references to it being anything other than a run of the mill AR. No optics shown and no barrel length mentioned. Nothing that leads me to think it belongs here. I miss something in the thread? Precision rifle shooting steel case ammo? Okay. It belongs in the ammo section. Additionally, more people will benefit from it there. I come here for bolt gun issues. |

You can replace the parts, not your eyes or life. |

Was that a LaRue Stealth upper or it is just the handguard?

Okay. Not a huge issue and not really an issue about it being here. Just thinking it better in the ammo section. Mods must have been here and if it's fine with them it's fine with me. My point is the issue has ZERO to do with precision shooting, it's about potentially defective ammo. Bye.

Have you cross posted this to the AR ammo section? If not it may be a good idea to let them know of the possible lot problem.

This. And this is really the only sub forum I post in. That and about a week ago I had a thread here recommending this same ammo. |

It's still fine ammo. I have about 3,500 rounds of it that I will keep shooting. Actually shot about 100 rounds this past weekend. Just a problem with the round/lot. If you didn't use any ammo that ever gave anyone a problem then you couldn't shoot any factory ammo and wouldn't even be able to handload

Right now I use quite a bit. I just dont know if I could ever buy this particular load again. Right now something in the back of my head says "don't do it!" |

I imagine it's like getting struck by lightning. Although it's extremely rare to get hit by lightning, I bet people that do are forever afraid of thunderstorms. You probably cashed in on a one in a bajillion chance and won't ever have a similar issue with that ammo, but I can understand your apprehension. |
