    Happy new year! Hope it's a good one for all. :)

    I reload .223 for ARs and use quite a bit of range brass. I have a fair amount of brass that has a head stamp of 'G' at the top with '5.56' in the lower left and a two digit year in the lower right. I full length size all of the brass and check it with a L.E. Wilson case gage. Well, the 'G' brass does not want to cooperate, and will be just a few thousandths too long, even after a second resizing operation.

    In the past, I have loaded some of these and shot them without incident (in 5.56 chamber), but lately have not had a real comfortable feeling about it. I don't want to try turning down my die because it sizes everything else just right.

    Any thoughts of advice??? Thanks in advance.

    Rumor has it, it was made by Federal for a Guatemala government contract.

    If it won't FL size the same as your other brass?
    It is too hard.

    Neck and shoulder annealing will fix it.

    Rumor also has it, the primer flash holes are smaller then standard and stuck depriming pins are fairly common.
    Any trouble with that??

    Lots of rumors floatin' around!

    As for the primers, I use the Lee Decapping Die for depriming. I do not use sizing dies at all for that purpose. I can usually tell when I am depriming one of the 'G' cases because the decapping pin will make a squealing sound as it passes through the flash hole! It's kind of weird, and only the 'G' cases do that. You can feel that it is a tight fit, but I've never had one that I could not punch out the primer.

    Thanks for your reply, RC. I will probably set these aside for annealing sometime. They seem like good brass.
