    Cimp?

    Does an 8 star crimp offer any advantages over a 6 star crimp?

    If you're reloading, it has to do with the folds already on the hull.
    Some empties have a 6 point fold/crimp, some are 8.
    If you use the wrong one, sometimes the crimp doesn't 'do' right.

    On new shells, I can't imagine that it would matter.

    OK People. Enough of this idle chit-chat.

    It used to be a paper shell x plastic shell thing... I don’t think there is any advantage in plastic.

    It seems to me that 8 point is usually on target type loads and 6 point is used on field loads. Just what I have noticed.

    There is no problem so great, that it cannot be solved by the proper application of high explosives.

    An 8 point crimp uses just a tiny fraction more of the hull than a 6 point. That is the only difference.
