    .223 Brass Question

    So I just bought a new ar 15... It's a palmetto built upper on a mag tactical lower... Anyway, I shot it 10 times today and noticed after picking up the brass that there is an nick/scratch (deep) in each and every case!!!:( exact same spot!!! Is this caused by a burr in the chamber? Something else?
    Thanks

    Your barrel chamber is just fine & there is nothing wrong w/ your rifle.
    Congrats and happy shooting!

    But I reload... And I think these deep scratches are enough to toss them and not use them...

    Depends on what type of ammo you're using. I noticed with my very hot loads the brass would actually imprint the chamber grooves.

    If you can post a picture of what you mean we can try to see the problem

    Not caused by the chamber but by striking some part of the rifle during ejection. Look around the ejection port and deflector for a small brass colored shiny spot, that will be where the brass is impacting and getting dented. I reload also and have not had any problems caused by small dents.

    Yeah thats not normal looks like there may be something in the chamber. I rarely come across brass like that.

    I would recommend removing the upper and the barrel, and physically checking for any burs or defect.

    Might be the brass is impacting the rear or front portion of the chamber port. Try changing buffer weights or shooting a different load.

    What brand upper are you shooting? (does it have a brass deflector?)
    Barrel length?
    Gas system length?
    What buffer are you running?
    Are the ejected cases landing consistently in the same area?
    Where are the ejected cases landing?

    It's common with ARs/M-16s. Don't worry about it. It will go away on the next firing. I've been reloading them for years and it's never been an issue. Most every 5.56 case I collected in my service days has that identical smilie.

    As the case is ejected it tumbles out hitting the brass deflector causing this. It is normal, I reload those cases all the time.
    My rifle and pistol are tools, I am the weapon.
