FC 07 headstamp torture test (Page 1 of 2)

Everyone bitches about Federal "FC" headstamp brass so I did my own testing.
Conditions: 70 degrees partly cloudy Rifle:16" CAR15, chrome lined 1-9 twist, Stag lower, nothing special. Case used: Federal, FC over 07 headstamp. Once fired starting length 1.743" after sizing ran through a dillion super swage 600. Web thickness:.178" Load: 24.5 grains of AA 2330 with 55 grain bullet, Winchester small rifle primer, 2.250 OAL. Average speed through a Chrony 1: 3016 F.P.S. Shot # starting length: 1)1.743" 2)1.744" 3)1.748" 4)1.749" 5)1.754" 6)1.758" 7)1.762" 8)1.763" trimmed to 1.752" 9)1.757" 10)1.759" 11)1.160" 12)1.758" This was all shot with the same case within 30-40 minutes. Case never split, ass end didn't fall off and I think the sun will still rise in the morning. The primer pocket did loosen up but the primers never backed out or showed any pressure signs. My dog did wonder why I kept walking outside and shooting the woodpile from 15'. My conclusion is it works for me. The primer pocket was a little loose to begin and about done when I stopped but I know from loadind these that they vary and this was one of the sloppy ones when I began. |

I did a similar test but with FC 223 brass from Federal Value Packs from WW.
All held up for 6 firings. Primer pockets were fine. The only problem that I see with this brass is that some of it is VERY short. Like under 1.740" short. The picture below is from a case that was around 1.738". The tip of the bullet caught on the feed ramp and the shoulder got all bent up. Had to hold the charging handle and butt stroke my rifle to get it out.

| Lao Zieh use "FC" long time from porice range. Arways road to velocity specs, whatever burret, or powder. Use first crass techniques, not ham-handed, un-observant, or sroppy. Have good tooring and measuring device too. Ammo arways first class, hot, and accurate in brack rifre. Discard after 5 reroads regardress. No worries, comrades. Lao Zieh |

Y'all reveling in New Found Enlightenment had best pay attention to exactly which variation of FC cases you're loading.
And for the bazillionth time, the thin web problem has never extended to other calibers of FC brass, or at least no where the severity found in the .223 Rem brass. For this test, we'll note the primer pockets started out loose and got looser as the shots progressed. |

| I believe FC 07 is military contract brass, is it not? Commercial brass does not have the year date. Military brass usually is built to a thicker standard because the contract requires it. Did the brass seem soft like Federal's commercial line or was it tough like other military brass? Did it originally have a crimped in primer? Swaging a crimped primer work hardens the case head and actually will allow the brass to achieve more firings at modest loads before the pocket expands. I avoid Federal commercial brass. One reload is the rule, then I scrap them. Mil spec is a different animal and I'll keep my mind and eyes open to the possibility that some of it is useable. |

If you look at the case mouth, where it is crimped, is it crimped a lot? It looks like it may be but its hard to tell from the photo. This normally happens when the crimp die gets screwed down too far. This case may have just been really long, engaging the crimp too much, crushing the shoulder. |

I disagree the thin web was notorious in 95-96 for .40S&W i actually had a NIB 180gr fed HS kaboom in my g23 now it could have been the glock or the ammo ...but Federal actually changed its .40 desgin in 96 to compensate for Glocks ..... BUT as for .233/5.56 I bought 1k of 06/07 brass its very nice ...on third loading on that ....no problems yet |

The facts are clear that there are some vintages of .223 Rem FC brass from their American Eagle ammunition that are good for one reload at best. The LC headstamp has been showing up in AE brass for about 3 years now, and recent runs of brass with FC headstamps have heads with web thicknesses comparable to other makes of brass. There is no clear break point that can be identified. Whether Federal would tell us, I don't know, and it's worth asking. It's also a fact that some FC brass has webs in the 0.145 inch thick range, and that this brass is substandard for reloading, at least at normal pressures. Even while this brass was the only common type, several people reported using it for several reloads with mild charges. That is a fact. Here's another fact: there are plenty of the thin web cases still in circulation or in storage. I have a few hundred set back for emergency use. This means that anyone that is prudent is checking the cases they have so they know the web dimensions in their cases. Knowing is everything. Guessing, assuming, or hoping it all works out is nothing. That is also a fact. |

The apes, or at least the ones that traipse through here, need to read the fucking manual so they understand the complete story. The information is not hard to find here, there are at least three ways, but all three require reading, and then comprehending what is read. I'm not 100% convinced that there isn't still some new loaded ammunition in stock out there with the old cases. But even if Federal has made a shift away from the old brass style, there's still lots of it in circulation, so reloaders shouldn't discount the possibility of getting it if they buy once fired cases. My point is that everyone should sure about what they're buying and loading. I've set the archive status and linked this thread under my post in the Gateway thread. |

Back in 2005-06 I had a batch that the primer pockets were so loose that the primer rattled upon the very first reload. By the second reload was attempted, the primer wouldn't stay in the case at all. This was FC .223 REM, not "FC 0X" brass which many have stated it a completely different critter. |

Unrelated to the case head thickness issue, I have a small lot (300+/- cases) of "FC 07" headstamped brass, and I measured the weight of 25 cases, And they were very consistent. All within three tenths of a grain, IIRC. I have found the the FC 07 brass is very short, in the 1.740" area. This was also the case for the "FC .223" cases, which were not as consistent in weight. I don't have my notes in front of me, but my suspicion at the was the FC 07 was from a government contract run. All the cases, 07 and .223, came from a police range. I personally don't trust FC .223 brass much beyond a couple loadings. YMMV. |
<Scythe> I find it hard to insert the AFG into my rectum and pretend that it's Costa
<Scythe> that's why I want Magpul to make a standard, rectum friendlier, vertical grip
<Scythe> then I can have a little Costa in me too
