Has anyone seen this kind of defect on a reloaded .223 before? I can't find any reference to this kind of defect, just wonder what causes it. It showed up on 3 R-P (remmington) and one KFA (?) headstamp. http://home.columbus.rr.com/prijohaman/Circle_Extrusion.jpg I'm pretty sure it is harmless to shoot, just wondering. Since it happened on 2 different head stamps, probably not a manufacturer thing. Thought it would have come out in resizing. The edges are pretty deep, you can easily feel the extrusion with your fingers. Thanks! |

Are these your reloads, or gun show reloads (or another source)? I wouldn't shoot one until I looked it over very carefully to make sure I understand the condition of the case.  Damn, it never occurred to me that anyone with a pressure gun would let the brass get into the used brass market. |
| I'd recommend that you don't shoot them. The deep score in the body weakens it, and could produce a major gas leak if one of them cracks under pressure. A leak could result in gas cutting of the chamber and/or blowing the internal parts of the magazine out. They may be fine, but the risk is rather large compared to the cost of 4 rounds. |
| Those cases are from a factory or ballistics lab and are pressure test cases. The circular mark is from their pressure test machine. I found a couple of these cases when buying once fired brass I don't know about shooting them and maybe the best bet would be to scrap them. |
Yep, it's either the piezo-electric tranducer or the copper crusher, the former being the most recent method for testing pressure. Could be from any of the powder makers, or even bullet makers too, who are putting out reloading guides. There were some Lapua 338LM cases over on Sniper's Hide that came from Australia showing the exact same marks. Chris |

Crop Circles dude, Government/Alien conspiricy.  Were they commercially manuafctuered reloads (ultramax and such?). The hive says presuure testing, I don't know. I have to agree with the scrap them thought, if it is deep enough to potentially comprimise the case then don't bother. Not worth your eyesight or taste buds it it KB.  |

Thanks everyone. I think the pressure test wins. I got them from a reputable reloader, once fired cases. So coming directly from the ammo manufacturer makes sense. What confused me was the 2 headstamps, R-P and KFA. Anyone know who KFA is? something something Arms I suppose :) They said they were safe to shoot, a normal pressure testing method that marks the cases, I would have figured the resize would take it out, maybe it took some of it out and the rest will flow back into shape after firing. I'll just hang on to them, someone above is right, no sense taking a chance on $1.60 worth of rounds :). Anyone shot something like this before? |
Klingon FireArms What I found was kfa Staatliches Arsenal, Sarajevo, Yougoslavia |
Thanks Perimedik, I found that too but didn't believe my eyes . I vote for Klingon FireArms and Crop (i mean Case) Circles, alien invasions and all that :) |
well, if they were fired from a pressure chamber barrel..how much pressure were the cases subjected too? 50, 60, 70k!! yikes!! I would put these in my "display" cabinet and use them for a conversation round!

DO NOT SHOOT THOSE ROUNDS I might be next to you at the range! Mike |
