Can Someone Tell Me About This Brass, Please!

FC 75.jpg

i presume that this is Federal Cartridge Company brass of 1975. I am curious, how does this brass compare to LC brass? It has been annealed and it is all once fired.
 
doc,
is there a chance that stuff it federal 2015? and not 75? how is the rim...it looks like its got and ejector mark at about the 9 o'clock position. some federal brass can be "soft" depending on its origin and service life. just means it will wear out faster that's all. hope this helps, I am sure others will join in.
cheers,
Doc

Doc,
i went back and felt a few more of the brass, there is a ever so slight nick, nothing really bad there, deff nothing like what i have seen on Rem UMC .223 brass that has come out of a dirty Mini 14! I have seen a lot of that stuff.. it would take a file to fix it! But it still shot great in a bolt gun.. this is what i will be using it in.. Took a few and completely prepped the bass,

And the nice thing is that they come in the same weight range as the LC i have left.. Which is about 20..

Federal brass.Looks like 2015 production. Other than the crimped primers it is nice stuff. My best ar loads are with fc 07 brass. My rifles liked it more than lapua brass. I know it sounds weird but could never get it to shoot as well as the fc brass.
 
I think you found your rifle some food...and running that stuff through a bolt gun should give you good service life. IMHO as long as you can keep your brass the "same" you will enjoy consistent performance. Not all brass has to be Lapua....but some brass takes more love to be the "same". FWIW I shoot a lot of LC, But I also use ww and hornady. I also have lapua set aside for the Palma gun too. I think you FC 15 is GTG!

I looked at a few of them with the micro magnification lens.. yeah.. it so appears to be in fact 15, but i swear, some of the strikes do look an awful lot like a 7 instead of a 1.
I hope that your right on this one.. when done, it will be weight sorted and shot in groups of the same weight, all the other things that i will be doing.. like resizing the body till is .001 less than the fired LC brass i have, turn the necks so that i will have .001 tension. Uniform the primer pockets, i have both the long and the short primer pocket cutter from Sinclair. Uniform the flash holes and deburr the inside of the flash holes, trim to 1.750.

Yes!!! Semper Fi
 
Ive been running FC brass for a long time (as well as every other brand) in my ar15s & bolt rigs, no issues with it to date. Most of it has over 25 loadings. I don't anneal.

What load were you or are you using with the brass, if i may ask you sir?

I know what you mean, I couldn't get Lapua 243w brass to shoot as well as Winchester brass.
 
That is good brass. Remove the crimp. None of mine were near the 1.750 trim length. For my match cases I did trim to same length. For the AR, I just load and shoot...
 
I had good results with Fc09, and have FC 15 by the 1000s. Looks the same as pictured. Decent brass; works well. I did anneal to reduce SD for my 600y loads and split necks after 15 reloads due to feed ramp scrapes.

Good brass.
 
Check the water capacity. LC brass is about 54.8 gr of water (weigh with a spent primer in place). I heard that Federal is now making NATO spec brass, basically identical to LC in water capacity. I don't know, but if it's about the same water capacity, it should shoot the same loads. The older Fed GMM brass has a capacity of about 57.2 gr of water, and will obviously get to higher velocities.

That seems like a lot of capacity for 223/5.56...

Well when i get some more of the brass prepped and have a case that is in the same weight as one of my older prepped LC cases, then i will try that. Thanks for the tip!
 
There was a period of time I want to say 10 years or so ago some very bad soft nasty FC 223 was out there. Primers falling out on one moderate book load, factory rounds same issue etc.

Yes, i remember that, but this being a "2015" run of civilian contract mil spec brass, i would have to presume that those issues of said 10 or so years ago would not be an issue with this brass..
