Case Broke in Half
This case ejected from my Mini-14 in two pieces. The Mini often dents brass in the middle and I wonder if this case was ejecting, then hit something and split? Anyone had this happen to them?

Dude, due to this, and the fact that you have a case completely split in half, I’d have that gun looked at by a gunsmith before shooting it again…

Reload? If so, maybe sized too small/too many times?

Wrong burn rate/pressure curve perhaps. Case is not finished expanding when the bolt trying to extract, and the case is still plastered to the chamber wall.

If this is brass that you loaded, you should look into adjusting your sizing die so you are not over-sizing the cases anymore.

I have never had one split just ahead of the rim in a 223/5.56 but I have had a bunch of them split in the middle just like the OP's did.

It was probably a 6th, 7th or 8th. This is what happens when you pickup unknown cases and use them "just one more time".

That all said, I primarily shoot and reload .308/7.62, so maybe that accounts for the difference I'm seeing.. |

308's don't have as thick of a case forward of the case head as a 223/5.56 so they stretch much closer to the case head than 223/5.56 do.

Before a good case would get ripped in half by a Mini-14 the extractor would likely shear through the case rim. Notice I said good case, not reloaded umpteen times to save some pennies. Even a slam fire is unlikely to rip a case into two pieces, there would be other results. If you're using reloads from an unknown source (both the reloader AND the cases) I'd stop using them as in right now. You could easily measure the case wall thickness and conclude whether or not the case was defective before it was fired. Start with the easy stuff. Range brass pickups are a no-no unless you know for a fact they were factory new (not factory reloaded) and saw them from box to ground. Even then, unless you were shooting them, who know what the shooter had loaded. For all you know they were 1/100th of a grain from a catastrophic failure and you picked it up and reloaded it. At that point it doesn't matter what your load was. This happens often with people who shoot shorter cases in chambers spec'd for longer cases like those who shoot 40S&W out of 10mms. They are relying on the case rim instead of the case mouth and it takes very little for that case to seat just a tiny bit deep. That case is stretching upon firing. Reloader take the case and trims it and reloads it. Not very smart aside from many people saying it's ok. Playing with fire. It's not the years and 1000s of rounds that didn't bite you, it's the ones that does that ruins your day.

Reload maybe once? We need all the details of who made/bought this round. If it was retail reload I think they only load once fired. If this was gun show reloads, who knows. It's why some people only shoot their own ammo. I warn others when I make my own ammo so they know the risk too.
Getting closer, it is for this reason I try to only pick up rifle brass that I know came out of a brand new box at the range or shot from my friends' guns. I also don't clean my brass to near perfection so if left at the range people don't mistake it for new brass. |

I used to have a Swedish Ljungman that did this with new PMC ammo. The cases came flying out in two pieces.

Theres been a few times where my 223 brass has been split. Never noticed when firing. It was noticed when picking up, and again when processing (whats this strange 9mm, short 30 carbine round?...oh yeah, its part of a 223 case). I think the worst 223 failures Ive had were from a suppressed SBR. Blown primer, and cracked rim. The firearm cycled, but case did not extract/eject and tried to feed another one in behind it. So when reloading, if the primer isnt tight, Ill put the case aside for depriming and retirement. I only have real issues with suppressed short gas systems on 223. For all 308, if that primer aint tight, its set aside for depriming and retirement because it seems to cause problems in all semi autos, including roller delayed. |
