    I found this at the range yesterday, was just curious as to what the deal with it is.
    It might be a common thing, but I've never seen it before. All input is appreciated.

    EDIT: Referring to the vertical lines running down it. I doubt it matters, but it's a .308.

    Thats wild. Looks to me like a chambering mishap of some sort. Like the chamber is rifled or something. Interesting indeed. I will be interested in all opinions as well. Hope I never have to see something lik that out of my own rifles. Something went badly wrong. was it only one or were there several like that? I am guessing only one, because the rifle had to have let the shooter know it wasn't right. Don't know.

    More than one! That's the crazy part. I found 3 pieces of 308 brass, and they all had it.

    It is a piece of brass from a Cetme or a HK. The roller block systems use the fluted chamber.

    Definitely from an hk fluted chamber.............. even my mp5 9mm did that........ silly over engineered and over priced weaponry. Not a fan of hk myself, but lots of people love them.

    So what is the supposed advantage they hope to gain from a fluted chamber aside from if there is a burr you are likely to get a stuck case?

    That is their solution for (supposedly) 100% reliable ejection/feeding.
    They are military/battle rifles after all, so they don't care about single use brass.
    Especially when they may be required to use NATO issued ammo built in "gawd only knows" where.
    Lots of sub-standard (by our standards) ammo out there in NATO land.

    I can't help but think that if you fired a substandard load that was over pressure for whatever reason that it would be extremely difficult to remove.
