    While out shooting at my other local shooting spot I found about 100 or so .223 sized casings. So I picked them up, but the head stamp is confusing me. I can't take a very clear picture, but I made a sample in paint pretty easy. Any help is much appreciated in identifying this brass.

    Ok so its federal brass, thanks for claring that up. But is it 5.56 since it doesn't say 223 rem on the headstamp?

    Is there a crimp ring around the primer pocket? If so, prolly 5.56.

    Federal Cartridge made in 2012. Highly likely that it was originally a 5.56 case. But who cares? You are going to be running it thru a 223 die. Which in turn will make it a 223 case.

    What makes you think there is such a thing as a "5.56 Case"?

    Incorrect terminology used by my self. What that was implying was, "a 223 case with a military style primer crimp loaded to 5.56 pressure spec." :D

    5.56 is thicker? Correct? So then even loaded to a .223 load still has more case pressure than a .223 case loaded to .223 spec?

    I don't reload but that's what I was under the impression of.

    Yes there appears to be a crimp.
    So if I remove the crimp can I use my cci small rile primers on it and load it as .223? Or do I have to buy military 5.56 primers.

    The only thing military/5.56 primer are for is to protect against slam fires in semi autos such as an AR15. They do that with a thinker than standard cup material. Standard/magnum small rifle primer are just fine, and have been used probably billions of times.

    Can I use small rifle magnum primers? What is the advantage of it?

    Yes, you can. Advantages? Nothing more than they are said to be more consistent than standard small rifle primers. I personally don't have and of my own numbers to back that statement. You'd have to ask a bench rest shooter.

    Not necessarily. The .223/5.56 case relationships are the same, unlike that of the 7.6x51 versus .308 winchester.

    Case weights/thicknesses vary from military case to civilian case no more than from manufacturer to manufacturer in this family of cases.

    Speaking of ultimate accuracy.........well, I've found case "thickness and weight" to be all over the place, mfn to mfn and lot to lot...........I don't assume it'll be "consistent enough" unless all the brass is from one lot#.

    But, for plinking ammo (using range p/u brass) who really cares?

    And, just because a chart says X weight, it doesn't mean that your's will be X weight.
    ___________

    Wolf Primers.

    People have been complaining. Wolf has expanded their line up in an effort to quell the complaints about their SR Magnum primers when used with 5.56/.223 loads.

    Use the correct product.

    _____________

    Using a standard or magnum primer.

    DYK, that some manuals spec a magnum primer with certain powders? Why?
    A: Some powders are said to be harder to ignite.

    That being said.......you're the reloader, it's your bench, your firearm, your life. Experimentation (within reason) is part of the reloading experiance. Proceed at your own risk. The manual writers don't want anyone to get hurt using their data. For LIABILITY sakes.......and being that this is an open forum. I'll just say to follow your manual's recommendations.

    Just choosing a "different brand" can skew your results.......

    And....

    IF you look at the various web sites, not all of them will specifically say that ONLY a thicker cup is used in their magnum (or military primer) vs. their standard primer. It could also be a case where the chemical compound is different (burns "hotter" or has “more brisance").

    In essence..........a magnum (or military) primer is usually said to have "less sensitivity" and "more brisance."

    Then..........

    Conversely, standard (or match) primers are usually said to have "more sensitivity" and "less brisance."

    That sensitivity with lower brisance, equates with accuracy. So, most shooters who are looking for accuracy will choose to use, a standard (or Match) primer over a magnum (or military) primer.

    ______________

    Military Spec primers and slam fires.

    This sort of question(s) about military primers in semi-auto firearms comes up often........

    Did you note the *?
    So, some re-loaders have been convinced that it's a, "must have." As for Me........"Nope."


    Aloha, Mark
